• Wireless connection disconnects and reconnects with a Netgear WNA1000

  - by William Berkenkamp

  Ever since I made the permanent switch from Vista to Ubuntu i've had wireless connectivity problems. From watching the network manager when it disconnects it seems like it turns off the receiver for some reason. Could it be bad drivers? I used their install software and the site doesn't really offer driver downloads. The adapter is a Netgear WNA1000 if memory serves, and I don't know much about the router except that it's a Motorola Surfboard. And I figure this might help a bit *-network description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:01:00.0 logical name: eth0 version: 01 serial: 00:1b:b9:a7:39:a4 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half firmware=N/A latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:40 ioport:d800(size=256) memory:feaff000-feafffff memory:feac0000-feadffff *-network description: Wireless interface physical id: 1 bus info: usb@2:1.1 logical name: wlan0 serial: 00:26:f2:8b:fb:38 capabilities: ethernet physical wireless configuration: broadcast=yes driver=carl9170 driverversion=3.2.0-24-generic-pae firmware=1.9.4 ip=10.0.0.36 link=yes multicast=yes wireless=IEEE 802.11bgn I have tried installing WICD and it didn't fix the problem.

• How to Install Broadcom Wireless Drivers (BCM43xx)

  - by Fer1805

  I'm having serious problems installing the Broadcom drivers for Ubuntu. It worked perfectly on my previous version, but now, it is impossible. I'm a user with no advance knowledge in Linux, so I would need clear explanations on make, compile, etc. Edit: For the command: "lspci | grep Network", I get the following message: 06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01) For the command: iwconfig, i get the following: lo no wireless extensions. eth0 no wireless extensions. When i follow the following steps (from the above link), there are a NO error message at all: open the 'Synaptic Package Manager' and search for bcm uninstall the bcm-kernel-source package make sure that the firmware-b43-installer and the b43-fwcutter packages are installed type into terminal: cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl' (you may want to copy this) and see if the term blacklist bcm43xx is there if it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf put a # in front of the line: blacklist bcm43xx then save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly). reboot 'End of procedure' Before (not ubuntu 11.04), if i wanted to connect wireles, i just went to the icon at the upper side of the screen, click, showed ALL the wireless network available, and done. Now, the only options i see are: Wired Network Auto Eth0 Disconnect VPN Enable networking Connection information Edit connection. lspci -vnn | grep Network showed: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] hope above info is enough for your help.

• Wireless internet connection connects but internet does not work (no packets received). Wired does.

  - by Rodney

  When I connect my PC via ethernet cable to my ADSL router it works fine. When I connect via Wireless it connects and the internet will work for a random amount of time and then stop working. It stays connected with a strong signal but no packets are received. My laptop/iphone are right next to it and wireless works fine. If I open the Wireless USB status, it says it is connected to my SSID with full strength (54 mps - I am 3 meteres away from my router) and the activty shows as Packets 594 SENT and 105 RECEIVED (this goes up VERY slowly) I have tried the following: Turned off anitvirus and firewall completely. Tested the wifi signal- I am writing this on my laptop which is next to my PC and also has full wifi strength. Tried a different wireless adapter - I dug out an old PCI wireless card - it does the exact same thing. Compared all wireless settings to my laptop. I can ping google.com and it replies (sometimes with packet loss) When I reboot the PC it will connect for a minute or two (random time) and then just stops again. I tried Firefox, IE etc. no joy I have updated all latest versions (Netgear WG111v2) and drivers Checked Event Log - nothing unusual Ping the router (and even connect as admin for the few minutes when the internet does work) Changed the MTU down to 1200 using DrTCP Checked Device Manager for conflicts - none. I ping the router from the PC (192.168.0.10 - 192.168.0.1) and it replies with 4 packets. BUT, on my router admin page (which I access via http on my laptop wirelessly) - if I ping 192.168.0.10 all packets timeout (pinging my laptop 192.168.0.12 works fine) My router admin page shows the leased IP address for 192.168.0.10 (ie it is definitely talking to the router initially) Now I am out of ideas - please help. I think it is an OS/Software issue as I have tried 2 different wireless adapaters (PCI and USB) with the same result but all other wireless devices work fine around mine). It's not the firewall. It is getting assigned an IP address correctly (my PC gets 192.168.0.10, my laptop is .12) It is assigned by DHCP. As soon as I plug in the ethernet cable it all works fine. Repairing the adapter sometimes helps but it will always stop working after a random time. The wireless adapter always shows as connected with Excellent signal but the internet does not work. I am running Windows XP SP3 and have tried a Netgear WG111v2 USB adapter. Thanks in advance! UPDATE: The internet seems to be working, it is just either sending packets too small or slow to work (some small pages load bits of them very slowly but then hang). XP seems to have a networking diagnostic app - here is the output: Last diagnostic run time: 08/30/10 08:16:38 IP Configuration Diagnostic Invalid IP address info Valid IP address detected: 192.168.0.10 IP Layer Diagnostic Corrupted IP routing table info The default route is valid info The loopback route is valid info The local host route is valid info The local subnet route is valid Invalid ARP cache entries action The ARP cache has been flushed Gateway Diagnostic Gateway info The following proxy configuration is being used by IE: Automatically Detect Settings:Disabled Automatic Configuration Script: Proxy Server: Proxy Bypass list: info This computer has the following default gateway entry(ies): 192.168.0.1 info This computer has the following IP address(es): 192.168.0.10 info The default gateway is in the same subnet as this computer info The default gateway entry is a valid unicast address info The default gateway address was resolved via ARP in 1 try(ies) info The default gateway was reached via ICMP Ping in 1 try(ies) info TCP port 80 on host 65.55.12.249 was successfully reached info The Internet host www.microsoft.com was successfully reached info The default gateway is OK DNS Client Diagnostic DNS - Not a home user scenario info Using Web Proxy: no info Resolving name ok for (www.microsoft.com): yes No DNS servers DNS failure HTTP, HTTPS, FTP Diagnostic HTTP, HTTPS, FTP connectivity info FTP (Passive): Successfully connected to ftp.microsoft.com. info HTTP: Successfully connected to www.microsoft.com. warn HTTPS: Error 12002 connecting to www.microsoft.com: The operation timed out warn HTTPS: Error 12002 connecting to www.passport.net: The operation timed out error Could not make an HTTPS connection. info Redirecting user to support call WinSock Diagnostic WinSock status info All base service provider entries are present in the Winsock catalog. info The Winsock Service provider chains are valid. info Provider entry MSAFD Tcpip [TCP/IP] passed the loopback communication test. info Provider entry MSAFD Tcpip [UDP/IP] passed the loopback communication test. info Provider entry RSVP UDP Service Provider passed the loopback communication test. info Provider entry RSVP TCP Service Provider passed the loopback communication test. info Connectivity is valid for all Winsock service providers.

• Computer Networks UNISA - Chap 8 &ndash; Wireless Networking

  - by MarkPearl

  After reading this section you should be able to Explain how nodes exchange wireless signals Identify potential obstacles to successful transmission and their repercussions, such as interference and reflection Understand WLAN architecture Specify the characteristics of popular WLAN transmission methods including 802.11 a/b/g/n Install and configure wireless access points and their clients Describe wireless MAN and WAN technologies, including 802.16 and satellite communications The Wireless Spectrum All wireless signals are carried through the air by electromagnetic waves. The wireless spectrum is a continuum of the electromagnetic waves used for data and voice communication. The wireless spectrum falls between 9KHZ and 300 GHZ. Characteristics of Wireless Transmission Antennas Each type of wireless service requires an antenna specifically designed for that service. The service’s specification determine the antenna’s power output, frequency, and radiation pattern. A directional antenna issues wireless signals along a single direction. An omnidirectional antenna issues and receives wireless signals with equal strength and clarity in all directions The geographical area that an antenna or wireless system can reach is known as its range Signal Propagation LOS (line of sight) uses the least amount of energy and results in the reception of the clearest possible signal. When there is an obstacle in the way, the signal may… pass through the object or be obsrobed by the object or may be subject to reflection, diffraction or scattering. Reflection – waves encounter an object and bounces off it. Diffraction – signal splits into secondary waves when it encounters an obstruction Scattering – is the diffusion or the reflection in multiple different directions of a signal Signal Degradation Fading occurs as a signal hits various objects. Because of fading, the strength of the signal that reaches the receiver is lower than the transmitted signal strength. The further a signal moves from its source, the weaker it gets (this is called attenuation) Signals are also affected by noise – the electromagnetic interference) Interference can distort and weaken a wireless signal in the same way that noise distorts and weakens a wired signal. Frequency Ranges Older wireless devices used the 2.4 GHZ band to send and receive signals. This had 11 communication channels that are unlicensed. Newer wireless devices can also use the 5 GHZ band which has 24 unlicensed bands Narrowband, Broadband, and Spread Spectrum Signals Narrowband – a transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies Broadband – uses a relatively wide band of the wireless spectrum and offers higher throughputs than narrowband technologies The use of multiple frequencies to transmit a signal is known as spread-spectrum technology. In other words a signal never stays continuously within one frequency range during its transmission. One specific implementation of spread spectrum is FHSS (frequency hoping spread spectrum). Another type is known as DSS (direct sequence spread spectrum) Fixed vs. Mobile Each type of wireless communication falls into one of two categories Fixed – the location of the transmitted and receiver do not move (results in energy saved because weaker signal strength is possible with directional antennas) Mobile – the location can change WLAN (Wireless LAN) Architecture There are two main types of arrangements Adhoc – data is sent directly between devices – good for small local devices Infrastructure mode – a wireless access point is placed centrally, that all devices connect with 802.11 WLANs The most popular wireless standards used on contemporary LANs are those developed by IEEE’s 802.11 committee. Over the years several distinct standards related to wireless networking have been released. Four of the best known standards are also referred to as Wi-Fi. They are…. 802.11b 802.11a 802.11g 802.11n These four standards share many characteristics. i.e. All 4 use half duplex signalling Follow the same access method Access Method 802.11 standards specify the use of CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) to access a shared medium. Using CSMA/CA before a station begins to send data on an 802.11 network, it checks for existing wireless transmissions. If the source node detects no transmission activity on the network, it waits a brief period of time and then sends its transmission. If the source does detect activity, it waits a brief period of time before checking again. The destination node receives the transmission and, after verifying its accuracy, issues an acknowledgement (ACT) packet to the source. If the source receives the ACK it assumes the transmission was successful, – if it does not receive an ACK it assumes the transmission failed and sends it again. Association Two types of scanning… Active – station transmits a special frame, known as a prove, on all available channels within its frequency range. When an access point finds the probe frame, it issues a probe response. Passive – wireless station listens on all channels within its frequency range for a special signal, known as a beacon frame, issued from an access point – the beacon frame contains information necessary to connect to the point. Re-association occurs when a mobile user moves out of one access point’s range and into the range of another. Frames Read page 378 – 381 about frames and specific 802.11 protocols Bluetooth Networks Sony Ericson originally invented the Bluetooth technology in the early 1990s. In 1998 other manufacturers joined Ericsson in the Special Interest Group (SIG) whose aim was to refine and standardize the technology. Bluetooth was designed to be used on small networks composed of personal communications devices. It has become popular wireless technology for communicating among cellular telephones, phone headsets, etc. Wireless WANs and Internet Access Refer to pages 396 – 402 of the textbook for details.

• Connect to new wireless network

  - by Shawn de Wet

  Wireless networking was working perfectly on my old adsl router. Then I moved to a new home that does not have adsl, and the router has been replaced with a new 3G one. I have worked through the following links: Connecting to a wireless network and http://ubuntuforums.org/showthread.php?t=571188 I have set the router from it's default WPA-PSK encryption to WEP encryption and also to No Encryption. But when I get to dhclient -wlan0, I keep getting No DHCPOFFERS received. Yet the 2 windows machines in my home connect fine to this wirelesss network (in all encryption settings). If I try iwlist scan I can see that the wireless network is indeed visible. Where do I start scratching to see where the problem may lie.

• Help making TP-Link Wireless USB Adapter TL-WN723N work consistently

  - by Savvas Katseas

  I've only recently made the jump to Ubuntu, using 11.10/64 as my only desktop OS. Everything seems to be working fine, except my USB Wireless adapter, TP-Link's TL-WN723N which is randomly connecting and disconnecting. The connection time appears to be random, too: I've experienced hours of connectivity and lots of connections/disconnections. I've tried searching for a solution, but what I find doesn't concern this specific USB adapter. I'd like some help identifying the problem... I've also recently switched to using a D-Link router as a wireless hub, which creates its own wireless/n network. Unfortunately this didn't solve my problems, as the new n network can be joined, but there's no connectivity to the internet. I know that's not much info to help others solve my problem, so please let me know of what else I can provide to make this a better question -- and possibly help others facing similar trouble. lsusb reports that I'm using Realtek Semiconductor Corp. RTL8188SU 802.11n WLAN Adapter

• Wireless network unstable and often WPA2 protected networks just don't work

  - by Pedro

  I have an issue with my wireless network,so that the connection is working for only a few minutes, after which my browser no longer is able to load pages, even if the wireless is still active/connected. Furthermore, most of the time WPA2-personal protected networks don't work, (yesterday was the first time it worked - for a few minutes). By "don't work" I mean that it seems to successfully connect, but the browser can't load pages. I am running Ubuntu 10.10 32bit, and my wireless card is a RaLink rt3090. No changes have been done to any settings since Ubuntu was installed - networking began working on its own after the installation - but as described in first paragraph not very well.

• Kubuntu 12.04 Won't let me search for wireless network

  - by Bora George

  Hello I'm running a brand new Kubuntu 12.04 single boot on my laptop, this is the first time I tried connecting to a wireless network. I tried using the network manager app allready on the task bar, but it doesn't let me tick the column to search for wireless networks, i.e. it will untick it automaticaly, it's dissabled by the software or the hardware, but I doubt it. I've tried searching the other questions on this site, and I can't see anything which helps with my problem. I know my wireless card is a Atheros AR9285, I don't think I installed any firmware for it, I'm sorry I can't offer more info but I'm completely new to networking and all that I have for the network to connect to are it's name and password of course.

• atheros wireless ar9285 driver

  - by nikola

  I have been having problems with wireless on Ubuntu 10 and above, Mint 11 and above. The problem is in the driver for the wireless... I can see that there is no driver installed and yet it works but reduced a lot, for example: on windows 7 ultimate 100% on distance of 1 meter (currently running) Mint Cinnamon 15 on same distance 70% when it goes under the 40 % it simply disconnects and than takes a lot of time to connect again I am new to Linux and I don't know anything about programming, yet I love the interface and look of the OS but don't want to reject it for couple of problems. There is, however, a problem with brightness control on laptop, it shows the notification and slider but with no effect The question is: Can somebody explain to me where to download and how to install the ar9285 driver for atheros wireless card laptop acer emachines eme529? or can someone explain this to me only for the LINUX MINT 15 http://www.jrhenkelmann.net/index.php?option=com_content&task=view&id=34 because the synaptic's interface is different than of mint 15 I KNOW this is Ubuntu community but the problems persist in all Linux versions

• Need a few reboots to connect to wireless

  - by Debajyoti Nandi

  I am running xubuntu 12.10 on my msi wind U100 netbook. I have a problem with the wireless connection. Whether the wireless connects automatically to a known wifi hotspot (both at home and starbucks) is temperamental. Sometimes I need to reboot one or more times to get it connected. Otherwise, it tries and keep asking me to enter the password (which is saved and when it works it does, so the problem is not with the password). Every time my computer awakes up from sleep the same problem. I have to do a reboot to connect to wireless. I searched everywhere but found no solution. I would greatly appreciate if someone has any solution. I will gladly share the hardware/software or config info, if asked, but I don't know exactly what to share and where to find them. Thanks you for any help.

• Wireless not functional

  - by Michael Berkenblit

  I am a complete newcomer to Ubuntu. Today I installed Ubuntu 12.04 onto an 3 or 4 year old laptop - an HP DV2221. Install went fine, except that I can't get the wireless card to operate. I see that there are drivers installed (Broadcom STA wireless) and it says they are activated, but the wireless light on the body of the computer is lit as orange, when it should be blue, and if I disconnect the Ethernet wire, there is no ability to get onto Firefox. I've looked at some of the similar questions on this site, as well as Googling the issue - mostly, I guess I don't understand how to navigate or do some of the fixes recommended - I'm fairly adept technologically around Windows, but know zilch about Linux and how to perform some of the fixes - so, if possible, please tell me how I get to the menus needed to rectify the situation.

• If I enable/disable my wireless device, my computer will panic

  - by Yinyanghu

  Now, I use Debian 6.0.6 instead of Fedora 16/17. But I still sustain the problem of my wireless problem. If I enable/disable my laptop wireless device or my usb wifi adaptor, my laptop will panic. It seems like all the processes stop at that time and I have to restart my laptop directly. P.S. I think I installed the drivers correctly and the linux kernel may have some bugs. For example, when I unplug my usb wifi adaptor or I use this command, ifdown wlan0 I encounter this problem. Wireless Device: PCI: 03:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01) USB: Bus 002 Device 005: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN

• Wireless/Bluetooth problems on t43p

  - by user75965

  I have been struggling to get my wireless mini pcmcia card recognised by 12.04. It suddenly stopped, mid session. I have taken it out and replaced with a couple of spares with slightly different serial numbers. One had no joy - 'unauathorised'. The other worked briefly for thunderbird but not firefox, it seemed. The network controller reads like this: 0b:02.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05) I have ordered a replacement from ebay, and hope I got the right one - used the the FRU number from the one that stopped working. But I have ALWAYS had no joy with my Thinkpad t43p Bluetooth and Ubuntu ( 12.04, and even 11.04 and 11.10, if I remember rightly). Do you think the Bluetooth problem will solve with a new mini pcmcia? Surely not, as it has never worked, whereas Wireless worked until a couple of weeks ago...

• Wireless doesn't connect in Ubuntu 10.04 Lxde

  - by David

  Problem I have a Dell mini 9, and the wireless has worked without trouble in Ubuntu and Xubuntu versions 8.04 and 10.04. However, after installing lxde, the wireless doesnt connect. Network manager recognizes the local networks, and will say that it is connected, but ifconfig does not confirm the connection or the existance of a wlan0. I have another Ubuntu 10.04 notebook that works fine. My wireless device is Broadcom BCM4312 802.11b/g What I have tried I have tried to remove and install network-mananager and inxi but neither work, and sudo modprobe wl returns WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.

• Can't connect to wireless without typing sudo modprobe b43 in terminal

  - by user90889

  I just upgraded to 12.04 on an old ACER Travelmate 5320 using Broadcom 4311. I wasn't able to connect to the internet through the wireless for a few days. It didn't even display wireless networks. I was finally able to make it work by following the instructions found here: http://linuxwireless.org/en/users/Drivers/b43#supported However, each time I log on to the computer I have to go to the terminal and type sudo modprobe b43 to make the wireless work. Is there somehow I can avoid this? I have used Ubuntu for many years but always relied on other people to help me with the technical stuff. The terminal is alien to me so I literally follow online forum instructions without knowing what I'm doing. Also, I tried many many things before I managed to make it work. So I'm worried I may have installed something that now conflicts with whatever the sudo modprobe b43 does. Thank you
