• Firmware/driver for Broadcom wifi card, PowerBook G4 running Ubuntu 12.04 [duplicate]

  - by user107831

  This question already has an answer here: How to Install Broadcom Wireless Drivers 40 answers This is my first time working with Ubuntu (or Linux), so please be patient. I am running Ubuntu 12.04-powerpc "Precise Pangolin" on a Mac PowerBook G4 with 1.67GHz processor. The firmware/driver for the wifi card is missing. For reasons not worth explaining, I cannot physically plug the computer into the network. I have another computer, a MacBook Pro running OSX, from which I can download files and port them by USB thumb drive. The wifi card in the PowerBook G4 is by Broadcom. The chip is BCM4306, rev. 3. The PCI number is 14e4:4302. I have downloaded b43-fwcutter_015-14_powerpc.deb and dropped it into the Home folder on the Ubuntu machine. However, it will not install. When I double-click, it opens with Ubuntu SoftwareCenter, but the "Install" button is inactive: I can't click it. There's a message beside the inactive button saying, "An older version of 'b43-fwcutter' is available in your normal software channels. Only install this file if you trust the origin." If I "right-click" the .deb file and open with Archive Manager, it shows me the "DEBIAN" and "usr" folders, but I'm unsure what to do from there...and fairly certain this is not the right way to do things. Maybe I have the wrong version of b43-fwcutter for my machine/version of Ubuntu? The documentation for this problem is a mess. It refers to all sorts of out-of-date Ubuntu versions and to an array of different "cutter" and firmware files. Maybe I'd be able to figure this out if I were a more seasoned Ubuntu user, but I have no idea why Sofware Center won't let me do the install. I would be VERY grateful for an explanation of how to get the wifi card working on this machine again. Thank you!

• Attempting to install netgear N300 Wireless USB Adapter on Ubuntu without a present internet connection

  - by Liz

  Hello Linux/Ubuntu world out there. I don't have internet presently on the desktop I am trying to install the USB wireless adapter on. This seems to be the problem, which if the hardware would work would theoretically fix the problem. I can NOT access the internet via anything but wireless. I am presently on my laptop searching for answers while trying to install this little device. So any advice will have to take that into account. Now I have tried so far, using WINE which does not want to work, I have tried Windows Wireless Drivers which doesn't want to work, I have tried Software Sources, Other Software and it will not acknowledge the cdrom as a repository stating errors like E:Unable to stat the mount point /cdrom/ -stat (2: No such file or directory) However I can open the CD icon on my computer and access and browse the files. The computer can read the CD. I can read the CD. I've tried just plugging it in and seeing if the computer will automatically recognize the hardware, and go from there. That does not work either. I have tested USB port to just verify that the USB port works. It does. My laptop recognizes the hardware, and would easily install the software if I prompted it to. The difference is that my laptop is Vista, and I HATE Vista. Any tips, tricks?

• Help with the RT3290 Wireless adapter

  - by Potek

  I know there is a lot of questions about RT3290 wireless adapter, but I read many many of them and noone helped me with my problem. So, I have the HP Pavilion dm1 laptop and I installed Xubuntu 13.10 on it. During the instalation it poped up that I'm able to connect to the internet via network adapter. I did it obviously, but it worked for like 5 seconds, then it said that network connection is down and I couldn't connect to my router, even if i could actually see network connections avaible. Then (when installation ended) I rebooted my computer. My network was avaible! I could connect and browse the internet smoothly. Next day I turned on my laptop and I saw my wireless connection is no longer avaible, so I plugged laptop to the internet via Ethernet cable and started to explore internet searching solution for my problem. I did this: How do I get a Ralink RT3290 wireless card working? And I was able to connect BUT my kernel started to panic every time I started Mozilla or any program that is connecting to the internet. Every tip i searched was almost the same as the link above. I tried to do this many ways. I even Reinstalled Xubuntu to do everything with clear system but the same thing happened. THEN I installed Linux Mint to check whether it is a major or just Xubuntu problem. Linux Mint responded even worse, because I wasn't even able to use terminal (I clearly messed something up). I would really, really appreciate every help, because I do want to solve this problem and finally be able to use Xubuntu/Ubuntu. I'm waiting for advice from anyone patiently. If anyone wants some details, just tell me which ones.

• SD Card only mounted after a reboot

  - by hattenn

  I have a Kingston 2GB MicroSD and I plug it in via an inconix MicroSD Adapter to the internal card reader of my Samsung N210 Netbook with Ubuntu 10.10, but it doesn't show up. Only if I reboot the system when the card's plugged in it shows up. Why does it need a reboot for mounting? sudo fdisk -l gives the output below. But I can only see the drive when I reboot the computer while the card's plugged.

• Can't connect to Wireless Network - Ubuntu 12.04 LTS & Sabrent A111N USB Dongle

  - by Ohgodwhy

  I've been trying to connect to this network for quite some time. I can't directly connect to the router with a Wire, but can access the Router with other wireless devices without any issues. I had previously tried several other Wifi nic's but none of them would load properly. Today, i went and bought a new (supported) Sabrent A111N USB Dongle, which said explicitly that it works with Linux 2.4 +. I popped the Dongle in, and low-and-behold it immediately said that there were Available Wireless Connections. I selected my connection and tried to connect, but it just loops constantly while saying Wireless Disconnected then attempts to connect again over and over. ifconfig and iwconfig both show my device in a ready and working state. However, iwlist wlan0 scan says that there are no results found. I don't get it... At one point, I could see the CPU in the DHCP client list under the router, but it doesn't fully make the connection (something about a timeout?). Any help would be appreciated.

• Can't install Linux drivers for ASUS N-13 wireless adapter

  - by jcc

  I have a USB N13 wireless Adapter with install CD-- For Windows. I downloaded drivers from ASUS FOR N13 for Linux. Disregard install CD that came with adapter; it's for Windows. I then downloaded Windows Wireless driver install program app from Software Center in Ubuntu 12.10. The problem is me. I am newbie with all things linux; software sources, G Debi, default archive manager, synaptic package manager and the Terminal. The downloaded driver file is a .zip file. I managed to extract it to a tar.gz file and then to open it to the contained files. When I use the Windows Wireless driver program it ends up telling me there is no .inf file and goes no further. It wants to install .inf file but I don't even see one in all the files. Can someone please help me . I think you can tell by my wording I don't have a clue. I hope this is'nt too chatty. I've tried to be explicit and to the point. Thank you. Oh, this is on an ASUS LAPTOP K53E. I've looked all over Ask Ubuntu and finally found some questions even on the N13 but they didn't help; still some differences in the exact problem.

• Is the BCM4306 wireless card ipv6 capable?

  - by horroricane

  I've been trying to connect with ipv6 enabled networks with my Broadcom Wireless card under Ubuntu 12.04. The wireless card model is BCM4306. $lspci $Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03) $Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10) I have been unsuccesful to connect through an ipv6 address, but I can still connect to a network when assigned an ipv4 address. While searching for an answer or a solution, I know the kernel can handle dealing with ipv6. So, what's left to question should be the hardware handling the connection. Unfortunately nothing comes up when I specifically try to search for information on BCM4306 ipv6 capabilities. I just tried using a wired connection to establish an ipv6 only connection to the network I'm on right now, but I got the same behavior of constant disconnections. Maybe it's not the hardware? I don't know.. I don't want to disable ipv6 on my machine as relevant networks I'll be connecting to will be using it exclusively, but I'm not sure what is wrong and which parts should I replace/fix to get this working.. Could someone please point me in a fruitful direction to get ipv6 working under Ubuntu 12.04?

• Wireless switch on Dell XT2 - strange behaviour of rfkill

  - by DyP

  I have an Dell Latitude XT2 using an Intel WLAN card (lspci lists it as "Intel Corporation Ultimate N WiFi Link 5300") running Lubuntu 12.04 with recent updates. The laptop has a hardware WLAN switch. I have problems activating the WLAN when booting with the hardware switch set to "off". The situation is a bit confusing, unfortunately. rfkill lists two WLAN devices (though lspci only shows the Intel one). This is the situation when booting with the hardware switch set to "Off": 0: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: yes 1: dell-bluetooth: Bluetooth Soft blocked: yes Hard blocked: yes 2: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes From some tests, I conclude WLAN is only activated when both, the dell-wifi and phy0, are unblocked by soft- and hardware. But I can only unblock dell-wifi after the hardware switch is set to "on". Procedure right from boot with hardware switch set to "Off": Soft-unblocking phy0 works as expected. Could be done by start-up script. sudo rfkill unblock 0: nothing happens. Soft block of dell-wifi not removed. Set the hardware switch to "on": phy0 gets its hard block removed. Still no WLAN. sudo rfkill unblock 0: both the soft and hard lock of dell-wifi are removed. WLAN is now active and works. sudo rfkill block 0: only adds the soft block as expected. WLAN goes off again. So, in order to activate WLAN, I have to use the hardware switch and afterwards (manually) run a script - that's a bit inconvenient. Does someone know a better solution? Maybe a daemon could help that listens to rfkill events to unblock dell-wifi after I have set the hardware switch to "on"? (sounds like another workaround) When booting with the hardware switch set to "On", nothing is blocked neither hard nor soft.

• AR9485 wireless card loses ability to connect after hibernation

  - by DrewDiezel

  This has happened twice now, the first time it happened I just reinstalled Ubuntu. The only things that I've been messing with in terms of networking, have been restarting the network-manager service after I resume from hibernate (because it never works right after resume, but restarting the service fixes that), and changing my mac address with ifconfig wlan0 down && ifconfig wlan0 hw ether 11:22:33:44:55 && ifconfig wlan0 up. using tail | dmesg returns a bunch of attempts to connect, saying something like authenticating ... okay you're connected! now I'm going to just disconnect because I feel like it. (reason=3). Any ideas? If it helps maybe I'll add a picture of the tail|dmesg output later. My wireless drivers are as follows: Atheros AR9485 Wireless Network Adapter Hamachi Network Interface Microsoft Virtual Wifi Miniport Adapter Realtek PCIe GBE Family Controller VirtualBox Host-Only Ethernet Adapter Here is a pastebin of some terminal outputs that could help. Also, the reddit thread has a few answers, for anyone curious. It's located here. It is entirely possible that it's just my school wifi blocking out my laptop, and my home wifi sucks. Wifi does work at places other than my home and school, however my phone can connect to both places. Here is a pastebin of the results of the wireless-info script.

• Very slow wireless connection (unrelated to power management) using Netgear N150 WNA1100 in 12.04

  - by vgaldikas

  I am using a Netgear N150 WNA1100 USB Adapter. The network driver is: ath9k_htc. When I use Ubuntu 12.04 my wireless connection is much slower than when I use the WNA1100 with my Windows 7 installation on the same machine. I have been researching this and the most common reason for this seems to be related to power management. However for me this is off by default. I had entered a bunch of different commands and, at one stage, I got it to work at full power. But then I rebooted the machine and it went back to slow again. After entering the different commands I was afraid that I may have messed something up, so I performed a fresh install of Ubuntu. I still have the same problem. My wireless connection is still much slower when using Ubuntu than when using Windows 7. I am not sure what other info could help... EDIT: Ok, I have made live usb from the iso file I used to install Ubuntu on this pc, and ran it on my laptop. Still the same problem. However la[top works grand on cable. I suppose this means that my wireless adapter or network driver can be eliminated as root of the problem.. So maybe to do with router itself? I use ZyXEL P-660HW-D1

• How do I turn on wireless adapter on HP Envy dv6 7200 under Ubuntu (any version)?

  - by Dave B.

  I have a new HP Envy dv6 7200 with dual boot Windows 8 / Ubuntu 12.04. In windows, the F12 key in Windows activates the "airplane mode" switch which enables/disables both on-board (mini PCIe) and USB wireless adapters. In Ubuntu, however, the wireless adapter is turned off by default and cannot be turned back on via the F12 key (or any other combination of F12 and Ctrl, Fn, Shift, etc.). Let me explain the "fixes" I've seen in various forums and explain what did or did not happen. These are listed in no particular order. (Spoiler alert: wireless is still broke). Solution 1? Use HP's "Wireless Assistant" utility to permanently activate the wireless card in Windows, then boot into Ubuntu to happily find it working. Unfortunately, this utility works in Windows 7 but not Windows 8. On the other hand, hardware drivers from HP are only available for Windows 8 for this model. Catch 22 (I could not find a comparable utility for Windows 8). Solution 2? Use a USB wireless adapter to sidestep the on-board device. I purchased such a device from thinkpenguin.com to be sure that it would be Linux-friendly. However, the wireless switch enables / disables all wireless devices including USB. So, there's my $50 donation to the nice folks at thinkpenguin.com, but still no solution. Solution 3? Following the Think Penguin folk's suggestion, modify the mini PCI express adapter following instructions here: http://www.notebookforums.com/t/225429/broken-wireless-hardware-switch-fix Tempting, but I then violate the terms of my warranty mere days after opening the box. This might be a good solution for an older machine that you want to get your geek on with, but not for a new box. Solution 4? rfkill unblock all No effect whatsoever. ubuntu@ubuntu-hp-evny:~$ rfkill unblock all ubuntu@ubuntu-hp-evny:~$ rfkill list all 0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Solution 5? Re-install drivers. Done and done. Ubuntu recognizes the device - perhaps even without re-installing the drivers? - but cannot turn it on. How do I know this? In the Network Manager drop-down menu, the wireless option is blacked out and a message reads something like: "wireless network is disabled by a hardware switch". Solution 6? Identify a physical switch on the laptop and flip it. There is no such switch on this machine. In fact, walking through Best Buy yesterday, I checked and not a single new laptop PC had a physical switch on it. All of the wireless switches are either the F2 or F12 key ... I wonder if askubuntu will not be plagued by this exact issue in the near future?

• Wifi problems with Ubuntu 13.10

  - by Sparrowhawk4

  I should probably say straight off that I am brand new to Ubuntu. I installed 13.10 alongside Windows 7 a couple of days ago and I've managed to clear up all the little problems, apart from with the wifi. My internet is fine using an ethernet cable. I can connect to the wifi, and it tells me that the signal is good, but for the vast majority of the time I can't load anything, and system monitor tells me that I am sending and receiving nothing. The problem is somewhere in Ubuntu. It works fine on Windows 7, my Android phone and all of my flatmates laptops. I know I'm not the only one with this problem, but the fixes I've seen either don't work or I don't understand them enough to carry them out. Help?

• Intel Dual Band Wireless-AC 7260 keeps dropping wifi

  - by Rick T

  My wifi Intel Dual Band Wireless-AC 7260 keeps dropping wificonnection drops and the network to which I was connected disappears from the list of available networks in network manager. The only way to fix it is to disable wifi and re-enable it How can I fix this. I'm using ubuntu 14.04 64bit. It mostly drops connections on the 5ghz network.

• Downloads killing internet on my home network

  - by Travis

  I am currently having a problem with my wireless. Whenever I try to download anything it kills the internet for every other application(tabs within the same browser, browsers on other computers on the same network) except the process doing the download. This occurs with everything from downloading updates to iso's. I am not using a torrent. It happens when downloading upgrades, browser downloads, or anything else. This problem does not occur when I use Windows 7 on the same computer and it stops killing the internet for other computers if I turn the download/Ubuntu off. I am using an ASUS G74SX laptop running Ubuntu 12.10 with Gnome 3.6. My wireless card is an Intel Corporation Centrino Wireless-N + WiMAX 6150 (rev 67) Thanks!

• Apport-gpu-error-intel.py crash

  - by artfulrobot

  Feeling disempowered by Ubuntu's new bug reporting policy/system. My Intel i5 machines have all experienced daily (if not more frequent) freezes, but it's very difficult to report bugs now and policy instead is just for ubuntu to collect counts; no way for me to see that anything is (or is not) being worked on. I've just experienced a freeze and now on reboot I'm stuck in a cycle of "Ubuntu has an internal error" (presumably Ubuntu never experiences an external error...) do you want to report it? Yes. Oh another internal error... It looks like this report could contain useful information. Is there anyway to make sure it gets provided to the people who can fix it?

• Minecraft flickers sometimes and colors get buggy on an Intel HD Graphics 3000

  - by Oskar

  I really like Ubuntu, but I always had to switch back to Windows just because I couldn't get my Intel HD Graphics 3000 to work. So, 11.10 came out and I'm trying to get things work in this update, so I can finally stay with Ubuntu and use it. Anyways, things seem to be more stable here, but they're still a bit fishy. I'm doing tests with Minecraft. Currently, there's only 1 minor bug. The game flickers from time to time and the colors get buggy or something I read that maybe I should update to kernel 3.1? Maybe 32-bit Ubuntu is better? It was impossible to play Minecraft in 11.04, but 11.10 is so much more stable.

• Frequent GUI pauses in Ubuntu 13.04 / Unity / Intel HD4000

  - by Simon

  I'm experiencing very frequent (and regular) GUI pauses on my system. Every 30 seconds (pretty much exactly) the GUI will freeze for maybe .25 to .5 seconds. The mouse stops moving, keys stop echoing and a stopwatch timer briefly pauses. I'm using the Intel Graphics driver available from: https://download.01.org/gfx/ubuntu/13.04/main I've looked in a few places and tried a few things for a solution: I've checked cron and anacron for scheduled processes. I've disabled background processes (eg mysql, postgres, apache) not that these were doing anything anyway I've checked the following posts and tried the suggestions there: Unity GUI pauses/freezes for less than a few seconds How to go about troubleshooting frequent system pauses I've watched the system using top and System Monitor and there are no spikes (or even blips) of cpu usage when the pauses occur. There are no obvious error messages in dmesg or syslog There is loads of free RAM (8GB+) and no swap usage If it helps it's a ZooStorm i5 laptop with a HD4000 GPU, 16GB Ram and an SSD. Any help / suggestions would be very gratefully received.

• Color distortion with Intel HD4000 over HDMI output - VGA is fine

  - by Simon Möller

  I set up a new system with i5 3570k gigabyte z77 d3h using integrated graphics (HD4000) and I've installed the 64bit Desktop version of 12.04. Connected to my Acer Screen via HDMI, the colors are horribly distorted. I think the biggest issue is that black appears as greenish. Over VGA everything is fine. Interestingly, I once observed that connecting both, the VGA and the HDMI cable at the same time, solved the issue. Ubuntu thought 2 screens were connected, I mirrored the image, and over HDMI the colors looked fine. However, after a reboot I am now unable to reproduce this behavior. I read frequently, that Intel hardware should be supported out of the box by Ubuntu but it doesn't seem to be the case here. Should I upgrade my Kernel? If so, which version would you recommend? Thank you for your answers!
