Debian Configuration :: Wireless Stops Working After Kernel Upgrade?
Aug 17, 2011
Testing distribution. Installed Linux 3.0 but left 2.6.32 on as backup. When I boot into the old kernel, wireless mostly works OK, but never when I boot with the new kernel.
Results of dmesg|grep wlan0 on 2.6:
[ 22.005102] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.196774] ADDRCONF(NETDEV_UP): wlan0: link is not ready

[ 30.694053] wlan0: direct probe responded
[Code]...
Noticing the Access Point looked like it needed the MAC address, I ran iwconfig wlan0 ap <MACADDRESS> and sometimes it will work, and wicd can connect to the access point. But sometimes the command fails to run.
This should be easy for the Ubuntu Gods to sort out:
I have a Sabrent USB 802.11N adapter. (I am using 64-bit Ubuntu in all below)
I plug it into a 9.04 box and it works fine. Plug it into a 9.10 box. Network manager sees it and can attach to the network, but has 0% signal strength, no internet.
Rebuild the 9.04 box with a fresh install to 9.10. 0% signal, no internet. Try 10.04 Alpha 2, 0% signal strength, no internet.
Rebuild same box down to 9.04. Works perfectly. 100% signal strength. I do all updates and then the upgrade to 9.10 using the USB. Everything works fine until the reboot. Then, USB connects, but 0% signal strength, no internet. Oh! ifconfig says the wlan0 interface is up, but it has a random ip address.
I don't mind using 9.04 because for the forseeable future, the box is just going to count aliens for Seti, but my wife wants it off the counter and I would like to upgrade someday.
In a hp pavilion 15 Notebook PC with Debian 8.1.After two hours or so wifi stops working. Network-manager does not give any indication of failure but some times a yellow question mark.

I'm running Debian server 5.0.6 and the latest stable version of Apache. I am hosting a website and it will stop responding after an unknown amount of time. In order to make the website work again I have to run /etc/init.d/networking restart. The server is running a static IP address and is not resetting when the website goes down. I don't know where to start looking.
I am currently using Debian Testing, managing my wireless connection with NetworkManager and the Gnome nm-applet. Both have just been updated: network-manager from 0.8.1-6+squeeze1 to 0.8.2-6 and network-manager-gnome from 0.8.1-2 to 0.8.2-4.On installation of the new packages, I have no problems. However, on a reboot, I can no-longer connect to any wireless connection. I am not prompted on start-up for the password to unlock the Gnome keyring and when I left-click on the nm-applet icon and then click on a network to connect to it, nothing happens.I do not think this is a driver or NetworkManager daemon problem. If I run "nmcli dev wifi" or left-click on the applet icon, NetworkManager seems to scan for wireless networks properly and returns a list including the one I wish to connect to.
I have a MyBookLive where i installed a Debian 2.6 kernel. The system is running fine so far. Because of an error message when apt-get upgrade (udev) i tried to upgrade to 3.16. Here's what i did:
- apt-get install linux-image-xx - apt-get install linux-source-xx - extract the source - copied the old .config from running 2.6 kernel over to the 3.16 directory - make oldconfig - make uImage - make modules - make modules_install - copied uImage to /boot
No error messages because its a headless device - its just not booting up.
I have a system that was upgraded from Debian 7 to 8. Unfortunately it is not able to boot from the new kernel 3.16. Only the old 3.2 kernel is able to boot. I could transfer a backup, install it in Virtualbox, redo the upgrade and I can reproduce the error..The last error before "panic" is this line

Intel Core i7-5500U with Intel HD Graphics.So I updated to the backports kernel and backports intel xorg drivers and I have the weirdest thing.Everything is stuttery even cinnamon desktop effects are no longer smooth. If I boot back to 3.16, everything is butter (except the screen corruption). Even my favorite wine game dropped 25% in fps.
I remember that on windows, if the cpu is too slow (pstate_min_speed), graphics is also stuttery. However, increasing /sys/devices/system/cpu /intel_ pstate/min_perf_pct even to 100% didn't do the trick. I suspect, that this measure is causing it: URL....
how to increase the performance again? I just found out, after running glxgears (with about 40 fps), that xrandr shows an available framerate of 40fps
xrandr Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 293mm x 165mm 1920x1080 60.00*+ 59.93 40.00
I guess that's what makes it feel slow. Do you know how to get that back up to 60 (fixed)? It seems like the screen refresh rate set in xrandr has no effect on the problem. When I boot, glxgears runs with 60 fps and everything is fine. After a while, it drops to 40 and the whole desktop keeps stuttering. if I change the resolution with xrandr and then change it back, it goes to 60 again for a while

I have a problem. I'm using the latest Debian stable, Lenny. I am trying to get my usb wifi card working. The Debian wiki advised me to upgrade my kernel to 2.6.30 using backports, because the drivers for my wifi chip are supposedly in the newer kernel.
So thats what I did. The install went fine. However, after rebooting the computer hangs when it is starting gdm. Only the desktop background appears with some fuzzy stripe over it, the mouse doesn't respond. Pressing ctrl+alt+f1 does nothing. I can only restart with ctrl+alt+del.
I can still use the computer with the old kernel. No problems there. I tryed disabling GDM and rebooting again with the new kernel. It boots up and works fine on command line. However when I type startx it hangs, just like before.
I'm not an expert, but I'm suspecting there might be problems with the graphic drivers in the new kernel. When I installed lenny at first, X started fine. However 3d acceleration was not functioning. I got help from IRC, I had to install some package to enable direct rendering. Don't remember which one anymore.

I am running Debian squeeze. A while ago I upgraded my kernel to 2.6.38 from backports. Just now I thought it would be good to upgrade to 2.6.39 from backports. Upgrade went fine, but after rebooting I get a kernel panics rightaway.
"No filesystem could mount root, tried:" "Kernel panics = not syncing: VFA: Unable to mount root fs on unkown-block(0,0)."
This is the first time one of Linux installations halts/panics on booting, so I don't know what to do now. I tried booting the recovery entry from the grub boot menu, but same result.
I'm running Debian wheezy on a Toshiba NB505 and I've noticed that the wireless connectivity can be painfully slow at times. I know it's not our home network because my desktop flies (running Windows).Currently, I have the driver from this guide installed. I went to Realtek's site to download the latest driver for this wireless card (RTL8188CE, the Linux/UNIX version) thinking maybe this more up-to-date driver would operate better than the one used in the guide above.Is there a possible way to install this driver, or should I just stick with the current driver I'm using from the guide above?
I have a Dell Mini 9 with a Broadcom wireless adapter. I've had it working for months on Debian Sid, but recently I updated the entire OS to get KDE 4.4 (I also went from a 2.6.30 to a 2.6.32 kernel). Something in that upgrade caused wireless to cease to work properly. The problem is similar to the one described in this thread, but no resolution is mentioned there: viewtopic.php?f=5&t=50892 I've gone through all the steps to install the STA drivers/wl module for it, and it basically appears to be working. Using wicd, I can see all the wireless networks in the area.
The problem occurs when trying to connect. When I try to connect to my WPA wireless network, it eventually fails claiming a bad password. When I turned the wireless network into an unsecured network, it eventually fails claiming it's unable to get an IP. I've also tried at the command line with wpa_supplicant and it initially appears to work but in fact it hasn't. I've also got Kubuntu 10.04 installed on this machine, and it can connect without issue (using the proprietary driver that Ubuntu's hardware driver manager allows one to use).Does anyone know what has caused this? I even tried the earlier kernel, so that's not it.
For quite a long time now, I haven't even needed to re-install video drivers most of the time. However, ever since version 2.6.36-0.dmz.4, they haven't been. I booted my system after installing that kernel, re-installed the video drivers, and when that didn't work, completely removed them and re-installed them, and it still didn't work. Well, I was told that the installation was successful but even after restarting it appeared that they weren't working. I installed 2.6.36-0.dmz.5 today and the same problem persists. I tried an older kernel version (2.6.36-4 something) and they worked fine.
updated my jessie by apt-get dist-upgrade and there was an error said there was something wrong with some database, and I needed to run some command, but after the upgrade I forgot to run the command. After I rebooted my system I found there was not any password needed for a normal user or the root. But if I change to the emergency mode, a root password is needed.
on my netbook I have a Debian unstable/sid system. A few days ago I did an apt-get (dist-)upgrade which I think also updated the X-Server. Since then my netbooks keyboard and touchpad are not working as soon as the desktop is started (I think gdm). The Keyboard works during the Grub selection and also in recovery mode (Root Terminal), so I'm sure its not a hardware problem. Could it be that the X-Server unloads the kernel modules for those two devices?Also if I plug in a USB keyboard or mouce they are working.
The computer networking works fine with a normal static setup, but adding a USB wireless device is not successful. It is my own network so the wpa-ssid and wpa-psk are known to work with Lenny and a previous wireless device.The device is recognized (lsusb) and the driver is confirmed to be in the kernel (lsmod). Here is the iwconfig output:
wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off
After typing: ifconfig wlan0 192.168.1.144 up I can ping that address, but it is not working. I have just done a fresh install of Sid so that I could get the 2.6.35 kernel which contains the ath9k_htc driver for the USB wireless device that I am using. The firmware is ar9271.fw but my source of that is questionable because it does not seem readily available. I am temporarily using a PCMCIA wired connection which is what I am using to connect to the computer via telnet. (This is just for convenience so as to avoid getting up all the time.) Here is the ifconfig output:
I am moving over to debian from ubuntu, and the latest install is to an acer aspire one netbook, the wireless card seems to be working and I can see available networks and even connect to mine (with WPA encryption) via the gnome network manager, however opening a browser or pinging both local and external machines all fail. its as if the OS does not not know to use the card. The wired works fine.
If memory serves the card is identified by lspci as Atheros AR5007.
There is no reference to wlan0 in etc/network/interfaces.
I do not have that system on now and have to leave for work, but I can post any further info from conf files etc as required when i get home tonight... Just thought I'd post a quick description in case I'm missing something obvious...
I upgraded from lenny to squeeze on a notebook and I can no longer connect to the wireless network. The computer is an LG notebook and the network card is ralink rt2860. I am using Gnome and NetworkManager. The wireless key is WEP hex. It was working fine with lenny till before the upgrade. After the upgrade, the network card stopped working. So, I checked
Then I reinstalled the driver with apt-get install firmware-ralink wireless-tools Then the network manager tray started working again and saw the network, but cannot connect. It was trying to connect but timed out and kept asking for the password. It is the correct password. I tried deleting the old connection and recreated a new one in the nm. But still does not work.
When I tried to configure the screen resolution using NVIDIA X server settings, I was told to run 'nvidia-xconfig'. I ran it, restarted X but my resolution is still stuck at the maximum of 1024x768. I've tried running the above many times with the same results. I even tried aptitude reinstalling but still the same.
atheros-firmware and firmware-realtek are installed from repo.
ifconfig does not show the network devices:
ifconfig -a does show them, i ran the commands ifconfig eth1 up and ifconfig wlan1 up, which resulted in them showing when typing ifconfig, however both still are not working.
(ifconfig)Also eth1 is only showing an inet6 address not an inet/ipv4 address and wlan1 doesn't show any.
Checked the bios and noticed that network devices were enabled so i don't think its my bios.
Also ran a SystemRescueCd which i got from here: [URL] .... With this live cd, the networking was working.
I still consider myself a linux newbie so if there is anything that seems misleading or incorrect please let me know.
Some history: Normally my wireless worked out of the box with ubuntu (2.6.35) with minor hiccups and few disconnect issues. In debian testing (2.6.32) all i needed to do was install the firmware-ralink_0.27_all.deb package and it would work properly.Today I noticed that there was a kernel upgrade from 2.6.32-5 to 2.6.37-1 available in Sid. I upgraded the kernel everything works properly but my wireless would not connect. I use gnome with network manager. Network manager would list all available wireless networks but not be able to connect with wpa/wpa2 security. I noticed that network manager was using the rt2800 driver which does not work properly with my wireless card. It also seems that kernel 2.6.37 removed the rt2860sta driver reference from its "source".
When i was using Ubuntu Maverick with kernel 2.6.35 i noticed that network manager would use the rt2800 driver. Normally I would be able to connect but every so often or after the computer would "sleep" I would not be able to reconnect to a wireless network without rebooting. I found this post on the Ubuntu forums that describes how to compile the driver from source and problem solved: http://ubuntuforums.org/showthread.php?t=1476007 I will for the most part, copy the steps that Sven6210 describes and modify for the debian kernel 2.6.37-1
Things needed before proceeding :
1.Gedit text editor program or alternative
2.Have gcc (The GNU C compiler) installed
3.These steps assume the system is configured with sudo, please make appropriate modifications tailored to your system.
I've been enjoying wireless for a long time on Squeeze (iwl3945) with KDE, but the recent network manager update stopped that. I've tried a few things, like going back to /etc/network/interfaces and ifup wlan0 that I use with Lenny, but still not working.
I have a problem with my laptop Dell Inspiron 1525 wireless on Jessie Cinnamon.
I have installed the b43 firmware and after that everything seemed working but just for a few seconds.
I have tried to reboot and after that I can't browse the internet just for a few seconds and after that Iceweasel loading and loading and nothing's happening.
I can't surf on the net just with cable but the wifi setup shows everything is okay 95% signal strength and connected. Also tried reinstall the firmware and reboot and it's all the same after.
Before I upgraded, I used Ubuntu 9.04 on my Playstation 3. It worked absolutely fine. A couple of days back, I decided to upgrade to ubuntu 9.10 using the update manager. The installation process seemed to go fine, until I booted up the new version. When I booted up, my mouse cursor wouldn't move, whilst my keyboard worked fine, I unplugged and plugged it back in and swapped USB ports, but it came to no use. I reinstalled Jaunty and tried the entire installation process again. After installing the new version again, the same problem occured, my mouse just wouldn't work.
When I type in the command 'uname -a' it comes up with something (I apologize, I am a Linux noob) to do with the 2.6.24 Linux kernel, Ubuntu 9.10 is on the 2.6.31 kernel. Is this the problem? I don't understand what is going on or what the solution is. My mouse is a HP optical mouse if that helps. I can't bring up the terminal window because my mouse just doesn't work, which is really annoying me.
I have used a quite obscure device called Cideko AK0b [URL] .... for quite some time now and it has worked perfectly for almost 2 years now, both in Wheezy and in Jessie. However since I made an dist-upgrade a while back the mouse has totally stopped working. The system works through wifi - strangely enough - but everything else works. Keyboard and gamepad buttons. The manufacture says the things doesn't work on linux and so far I have proved them wrong.
But now the mouse is just out right dead no matter what I do. Have looked into mouse autosuspend but no avail so far. My suspicion is systemd but that is as good as any guess.
