• Broadband wireless drivers don't work

  - by user88235

  I have a Dell Latitude E6520 which is a Ubuntu 12.04 certified hardware. However the driver assigned to the Dell Wireless 5630 (EVDO-HSPA) Mobile Broadband Mini-Card doesn't seem to work. When I boot in Windows 7 I connect to Verizon dialing *99# with no username or password but it won't connect using Ubuntu. The windows drivers are from Novatel Wireless Inc 1.0.0.6 if that helps. This is also an internal card not USB and the hardware Id is USB\VID_413C&PID_8194&REV_0002&MI_00 If anyone can help me with obtaining the correct driver or maybe some other way of getting it to work I would be very grateful. My job requires traveling and I need internet access but hate using Win7.

• Proper Drivers for 10.10 Realtek RTL8176 Wireless and Synaptic V7.2 Touchpad Devices

  - by av7000

  I have a new Toshiba Satellite L645-S4059. This is an Intel i3 64 bit machine. Two problems have occurred that I would like to fix before transferring my work from my old compaq laptop. First I can't get the wireless driver to work properly. I went to the realtek driver site and couldn't find the 8176. Instead I was shuttled to the 8188 which uses a 8192 software release. I am not sure if the kernel is just missing the name. Second I have a synaptics V7.2 touchpad which is just flaky. It eventually freezes up so I am just using a USB mouse. Appreciate anybody's experience on this.

• Wireless driver - how to load manufacturer's STA file (Ralink 3290)

  - by Matt

  Caution: I'm a newb. Hardware: Giada i35G, cedar trail atom with nvidia gf119, railtek ethernet and Ralink 3290 for wireless. Already accomplished: Installed Ubuntu 12.10, loaded GPU drivers and redirected sound out through GPU card to HDMI. Ethernet works like a charm. Issue: Can't get my wireless up and running. There seems to be no package to which I can simply run a sudo get-aspt install ... I found the corresponding Linux driver from the manufacturer's site, but I have not managed to find out what to with the file. Here's the manufacturers site: http://www.ralinktech.com/en/04_support/support.php?sn=501 I get a file with the following name: \2012_0508_RT3290_Linux_STA_v2.6.0.0.bz2 I hope somebody might be able to tell me what to do next. Thanks for reading and apologies for potentially asking a trivial question. Best regards, Matt

  - by Anwar Shah

  I have Intel Graphics Card, which have model number GM965. It is on a Notebook, (Lenovo 3000 Y410). My Ubuntu Installation worked good until I upgraded to 12.04. It was a fresh install. The Graphics performance is poor compared to Natty, Oneiric. In the details tab of System Settings, Graphics driver is shown as "Unknown". I have upgraded the xserver-xorg-video-intel package to version 2.19.. from 2.17. But still same. So, My question is How can I install latest Intel graphics driver for my Chipset? or Is there any other method to fix the problem with graphics.

• Wireless iwconfig rate auto too low

  - by Jamie Kitson

  Hi, left to its own devices my wireless connects at too low a speed. I have a 20meg internet connection and my wireless is slowing it down to like 3meg. When I reboot into windows it's fine. When I run iwconfig eth1 rate 24M or even 48M the connection is much faster and runs fine, why won't it automatically go higher? Is this the fault of the driver? I am running Broadcom's driver compiled from source. Would adding iwconfig eth1 rate 24M to rc.local be the right way to force it at boot? Output from iwconfig when rate=auto: eth1 IEEE 802.11 ESSID:"honeypot" Mode:Managed Frequency:2.417 GHz Access Point: xxx Bit Rate=1 Mb/s Tx-Power:24 dBm Retry min limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=5/5 Signal level=-47 dBm Noise level=-91 dBm Rx invalid nwid:0 Rx invalid crypt:2 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Thanks, Jamie

  I know this is common question but i found no suitable answer, so i am asking this again. I installed ubuntu 11.10. I found the bug for ath9k, so set first network boot from BIOS menu.

• Wireless icon shows grey box

  - by donald

  Hello I am running kubuntu 13.10. I had to install using the server disk and did a upgrade to the desktop version to enable full disk encryption using multiple drives. For some weird reason when I move my mouse over to the wireless icon which has an red circle and a line through it, up pops a grey box with nothing in it. This stops me from chosing which ssid's I can connect to. Ubuntu has the drive for my wirless card and it is working verified using #lspci | grep Network Centrino Wireless-N 2230 I am connected to my network from the install wizard but I need to be able to choose which networks. Please help.

• No signal to monitor after driver install

  - by Hossam Riyad

  After installing 10.10 I used Hardware Drivers (Jockey) to install the graphics driver v11.2 for my ATI HD 5770. After restarting to activate the driver all went well and the boot screen showed up but not like the normal one the text was rough on the edges and after the boot finished the screen turned black and no signal. I have found some forum discussions about that issue but no fix worked for me. I use a DVI to VGA adapter and I have a View Sonic E70F CRT monitor.

• Can't connect to Wireless Access Point after installing proprietary drivers

  - by user6554

  I had Windows Vista Basic installed on my computer and I replaced it with Ubuntu 10.10. I then preceded to do the following: I downloaded the wireless driver from 'additional drivers' I enabled my wireless card And now it won't connect to my router but my game systems will. Then I downloaded WiFi-Radar  which did not seem to fix the problem. I still cannot connect to the Internet. I have done an exhaustive search of the Internet and turned up nothing.

• Wireless not working, no driver showing in the Additional Drivers window

  - by edit lopez

  I am a new user of Ubuntu. I have a Asus Q501L laptop that came preinstalled with Windows 8, but I wanted to move from Windows and try something new, so I just decided to install Ubuntu without thinking to much about it. The problem I have is that I can't install the additional drivers. When I go to to Additional Drivers nothing appears, it just says: no proprietary drivers are in use and in small letters continues: a proprietary driver has private code that Ubuntu developers can't review and improve. security and others updates are dependent on drivers vendor.. I can't even use the wireless connection. I really don't know what to do. I tried to download the drivers from Asus, but when I tried to install them it said: an error occurred while loading the archive. Also I don't know the model of the PC wireless card. If there is something I can do to find out that please tell me. Thanks!

• Aser Aspire 3690 WIreless Not working, new Ubuntu user

  - by drew

  I don't know that much about Ubuntu, but I put it on an Acer Aspire 3690 Laptop (replaced Win Vista). Everything seems to work fine, but the wireless connection. It says "FIRMWARE MISSING". It detects that I have a wireless card, so I don't know what to do. I've already used the "ADDITIONAL DRIVERS" thing, and that didn't work. I've googled and have not found anything helpful. I don't really know what I'm doing, so can your directions please be kindergarden level? Thank you very much for any help you can provide. I really appreciate it.

• Can't find ALL wireless networks, just my neighbours

  - by motoringeek

  Been playing with live discs since 10.10 but now have gone ahead and dual booted. I have a Acer 5742z with a Nplify 802.11b/g/n wireless connection. The install went well and drivers seem to be working. BUT, although wireless detects some local networks it doesn't find mine. I have WPA-PSK security on my modem, could this be the problem?? I don't want to change my modem settings as all my other WIFI devices are contected to it. So I need help in finding my home network. A step by step guide would be useful. I am using Windows 7 now to write this but would love it if I could use Ubuntu online. I only can when I connect an Ethernet cable. Thanks in advance.

• How to prevent wireless network asking password when briefly out of range

  - by Ian Mackinnon

  When I'm connected to a wireless network from quite far away I sometimes briefly lose the connection. Then Network Manager prompts me to re-confirm the password as if it suspected that was the problem that caused the loss of connection (the password is already filled in in the dialog box). Is this normal behaviour? Can I prevent it from happening and have Network Manager automatically reconnect without the password dialog box when the wireless network comes back into range? I'm using 10.04 (32bit, Gnome) on an Acer Aspire one.

• Unable to keep the connecting using a wireless bridge

  - by dan

  I am running Ubuntu 12.04 on a dell inspiron desktop (core 2 duo) and am using wicd to manage my network/wifi. I've found that the WiFi card in the machine has trouble staying connected to my router (I believe this is a function of distance between the two), so I've taken an old Belkin F5d7231 wireless router and installed dd-wrt on it to use as a wireless bridge hoping that it will have better reception. I think everything up through the wireless bridge is working OK since I have no problems accessing the internet through it with my MacBook. The problem arises when I try to hook the ubuntu machine up to the wireless bridge. It will connect for a few minutes, but it will quickly disconnect without clear triggering event; it may be more likely to disconnect if there is a heavy traffic load going over it (could be something as simple as "cat big_text_file" in an ssh session). I've tried switching from dhclient to dhcpcd without much improvement. Here is the output from the syslog when it connects: Jun 30 17:10:08 Chicabuntu dhcpcd[28278]: wlan1: dhcpcd not running Jun 30 17:10:08 Chicabuntu dhcpcd[28278]: wlan1: exiting Jun 30 17:10:08 Chicabuntu dhcpcd[28312]: eth0: dhcpcd not running Jun 30 17:10:08 Chicabuntu dhcpcd[28312]: eth0: exiting Jun 30 17:10:08 Chicabuntu avahi-daemon[1041]: Interface eth0.IPv6 no longer relevant for mDNS.

• Broadcom BCM4313 wireless slow and high-latency

  - by Florin Andrei

  Ubuntu 12.10 64 bit on a Dell Latitude E6330 laptop. Wireless is pretty slow. It gets connected quick enough, but then it acts like a dialup connection. My ssh sessions over WiFi are slow and laggy. Even browsing is slow, the pages are loading like it's 1998. This does not depend on the access point, it's the same both at home and at work. Other systems work fine on these access points. I had an older Dell laptop before, different WiFi hardware, and it was much faster over the same wireless access points. Is this a known issue with this hardware? If so, any solutions?

• Choose at GRUB menu whether NVidia driver should be used

  - by RobinJ

  For some games, I need the nvidia-current driver, but when it's enabled, I can't get my work done as it messes up everything. So is there a way I can get two options in my GRUB menu? One wich will load my operating system with the nvidia-current drivers, and one which will use the default non-proprietary one? It seems a bit stupid to me to have 2 Ubuntu installations (one for games, one for the rest). But I can't get my daily work done with the Nvidia drivers enabled as it messes up some applications, randomly freezes the system, etc. But I still want to be able to play some games. If there's a way to just load and unload the nvidia-current driver with a script or something, that would also be welcome.

• Can't connect to wireless on Lubuntu

  - by migwke

  I have a CISCO 802.11b WIFI Mini PCI LAN card in my IBM ThinkPad T30 laptop. Is this wireless card compatible with Lubuntu? I have Lubuntu installed and it just won't connect. It keeps saying that it is trying to configure then it says that it is connected but it does not work. I know that the wireless network is working correctly because I can connect to it with all my other devices and it works on this very same laptop when I am running Windows. I added the following commands to blacklist.conf, but still no luck blacklist padlock_aes blacklist geode_aes

• Installer says I'd need a wireless firmware, but WLAN works without it out of the box

  - by unor

  While installing 12.04.01 (Alternate) on a netbook (Samsung N150Plus), Ubuntu informed me that I'd need the firmware brcm/bcm43xx-0.fw. I skipped this step. If I understand this page correctly, the mentioned firmware is a WLAN driver. However, after the Ubuntu installation was completed, the WLAN worked out of the box. After a few minutes, Ubuntu informed me that there is a firmware update available, which would be the mentioned firmware. Do I need to install this? Is Ubuntu using some kind of "lite" WLAN driver and I might run into problems with certain networks in the future, if I don't use the firmware? Would there be benefits in using the firmware? (maybe longer runtime because of lower consumption?)

• Broadcom 4365 wireless driver with 3.4 / 3.5 kernel

  - by zaid

  I used this package to install the driver on 3.2 Kernel and it was working perfectly. Unfortunately the system used to freeze randomly with 3.2 kernel so I installed 3.4 kernel, now there is no freezing, the only problem is that my wifi card is not working, I tried to re-install the package, but didn't work. I can see the driver in the "additional drivers" and it say that it is active, but when I execute iwconfig it doesn't show up. I've even tried ndiswraper and that didn't work either. my lspci: 01:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01)

• After upgrading to Ubuntu 12.04, my broadcom wireless sta driver is not working

  - by Nuwan Aluwihare

  I upgraded my HP DV5-1000US Laptop to Ubuntu 12.04. But I cannot get it connected to the Wireless. I went through the settings, Hardware, Additional Drivers and it says that "No proprietary drivers are in use on this system". Also it says "Broadcom STA Wireless Driver" is not activated. I tried to activate it after got my laptop connected to the net through a wired connection, but it says "Sorry, installation of this driver failed. Please have a look at the log file for details: /var/log/jockey.log"

• Ubuntu 14.04LTS - runtime video card configuration through Radeon driver

  - by RJVB

  How does one configure Radeon video cards when using the open source Radeon driver - power profile, vsync, etc? Why I try the widely documented solution (against overheating) that worked for me under LMDE (confirmed with kernels up to 3.12.6), I get the following error: $ sudo cat /sys/class/drm/card0/device/power_profile default $ sudo sh -c "echo mid > /sys/class/drm/card0/device/power_profile" sh: echo: I/O error Exit 1 And when I try suggestions from Arch's ATI wiki my modifications are simply ignored: $ sudo cat /sys/class/drm/card0/device/power_dpm_force_performance_level auto $ sudo sh -c "echo high> /sys/class/drm/card0/device/power_dpm_force_performance_level" $ sudo cat /sys/class/drm/card0/device/power_dpm_force_performance_level auto Is this something Ubuntu specific, or something introduced with the 3.13 version of the Radeon driver? I'm encountering this on 2 laptops, one with a Radeon HD6290 (integrated GPU), the other with a discrete RV710 card. The RV710 needs a specific power setting to prevent overheating under LMDE, fortunately it doesn't seem to overheat with the Ubuntu default setting.

• Internet Timeouts with TP-Link TL-WN821N wireless usb stick - existing solutions dont work

  - by Sheena

  I'm running Ubuntu12.04 and I'm trying to get a TP-Link TL-WN821N to work. The solution from Internet Timeouts with TP-Link TL-WN821N v2 wireless usb stick didn't work for me. Neither has anything else... I've installed rtl8192cu as per instructions I found elsewhere to no avail. The symptoms I am experiencing are: When I plug in the device the PC can see and connect to wireless networks fine. The network I'm using has internet access and the signal strength is pretty strong. I can't ping and I can't browse the internet (timeout). Any ideas? I'm not sure what the next step would be or what information would be useful at this point.
