Ubuntu Networking :: USB Wireless Stops Working After Upgrade?
Feb 10, 2010
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.
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 [ 28.644779] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 30.688053] wlan0: direct probe to AP 00:19:5b:06:9f:ba (try 1) [ 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.
I'm having some problems with wireless, it works fine on boot but after a while pretty much randomly, it can be a few days or it can be a few hours, it stops working. I'm not sure which command would tell you what and it would take a little while to debug it because like I said it's random, but if anyone knows what to do please tell me! I'm on Lucid Lynx 10.04.Another something that's really bothering me (But not related to wireless) is that for some reason when I restart my computer, the top panel keeps changing the applets locations.
On a fully updated Ubuntu 9.04 system, I had successfully configured wvdial to connect using a USB modem ("Update" brand) with an ID of 067b:0611 (uses the pl2303 driver module). In considering an upgrade to Ubuntu 9.10, I tried a LiveCD and was unable to connect using wvdial. However, because I had made the CD a couple months before, I went ahead with the upgrade (via the internet; not a fresh install) in the hopes that it would end up working or I would be able to find a solution for it.
The Problem: The upgrade was a success as far as I could tell, but when I tried to connect to the internet with wvdial, I was not able to. I checked the wvdial.conf settings to make sure they were the same as before, added some new ones I thought it might need, unplugged the modem and replugged it, restarted my system, etc., but all to no avail. Whenever I would try to run wvdial to connect, I would get the following output:
Code:
--> WvDial: Internet dialer version 1.60 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ
[code]....
This was different than the output I used to get with wvdial, but when I went over to my browser (Firefox) the internet worked fine. I'm assuming my email client and other things will work okay as well, but have not tested them as of yet.
A final touch I did to make connecting a bit less 'painful' was to right-click on the panel (at the top of the default Ubuntu screen), and click on 'Add to Panel'. Then I selected 'Custom Application Launcher', chose 'Application in Terminal' for 'Type', gave the launcher a name, pasted in that 'horrifically' long command line above, gave a brief description in the 'comment' box, then pressed 'OK'. Voila! I now have a launcher on my panel that with a single-click will bring up a terminal screen where I enter my sudo password and it connects. Then when I want to disconnect I just go back to that terminal, press Ctrl+C, which promptly disconnects me and causes the terminal to vanish into thin air.
Now, I don't know enough about this stuff to know why this command worked and wvdial didn't, but if you know, feel free to post a reply. Or if you'd like to see what settings I had for wvdial that worked in 9.04 but not in 9.10, let me know. Or if you think it's worth checking to see if this should be posted as a bug in either wvdial or Ubuntu, you can mention that as well.
My Ubuntu when i start it up, go to the wireless networks , try to connect to my network it trys to connect stops than says disconnected. My internet card is a Cisco Aironet wireless (idk the model number)
Bus 001 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.
I have a problem with my wireless connection in ubuntu (natty with amd64bit) There seems to be intermittent disruption in my connection. Havent seen a pattern as yet, though it happens once a day. After that I cant get it to work at all and only restarting + reconnecting the USB device helps. Dont know what is going on.I have already read these pages : Commands and Wireless Troubleshooting.Here is my line of though1) Given that I am able to connect other devices to it while I am not able to connect through this desktop, I think the router is OK.2) I am able to work with it after restart + re-connection . And so the driver is OK and is loaded. The driver seems to be oK and loaded even while I am not able to connect.So why is this happening and how can I get this under control without having to reboot and re-connect the device everytime.Here are the output for the commands which will give you a more detailed idea of the process. Before reboot while I was not able to connect:

My Acer's Wireless randomly stops working until you fully shut down and start the computer.(Not Restart but Shutdown->Powebutton) I am using Ubuntu 10.04 Lucid.
I am wondering if anyone knows why it would stop working properly, and/or how to fix it?
And since this is a off and on problem I might not be able to provide details immediately from time of crash, since I need my computer on the wireless.
One symptom that really stands out is that the cooling fan is spinning as fast as it possibly can and processor usage is spiking around 80/200 on a process called phy0.(relevancy unknown)
As I was typing this post on my other computer, my laptop crashed and I lost the lshw -C Network output I had. If asked to, I will post the one from when it is working. Also I will post any other info you need from when I can.
I'm running a Source Dedicated Server on my Ubuntu laptop, and to connect to it via external IP from other computers in the network I need to enable loopback in my router.This was working fine, but then I disconnected my laptop for a few days, and when I came back the wireless stopped working on my Xbox. I reset the router to factory defaults, and then setup everything again. It was all working fine until I enabled loopback again and power cycled my router. Now every time I do that, the internet on Ubuntu stops working and the wireless on the Xbox stops working.
Edit: You can ignore this I guess. It seems I was actually DISABLING loopback by enabling that router option, which I guess caused this. Strange, because the first time enabling this option was the only way to get my external ip to work. Oh well, everything is fine now.
I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?
I have a Dell E6500 with and Intel 5300 wireless agn card running Lucid x64. Wireless works fine and speeds are great except when I download with either the browser or thru a torrent or even updates. Once I get to around 100 megs in to the file wireless stops working and the only way to get it working again is to disconnect and reconnect to the AP. I have installed the back ports and tried several other fixed to get this to work but nothing has helped. One more note this happens on 2 other wireless routers that I have tried so I know that it's not limited to my Linksys.
I have one major problem that is going to cause me to switch back to windows. My wireless network shows connected and works fine for a while but periodically stops working. It always says it is connected but sometimes stops working to where I have to disconnect and reconnect for it to start back up again.
My wireless LAN connection on this machine occasionally stops working. The network traffic bar shows periodic very small transmissions but the failure of all network dependent applications (Firefox, package manager, etc.) indicates to me that the machine is no longer talking to the net. I can fix it by reselecting my home network in nm-applet from the drop-down list. This causes the machine to disconect, reconnect and all is well for some random period of time thereafter. Here's some data:I'm running an HP Pavillion laptop.
Code:
~$ lspci | grep Wireless 02:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
I don't know if this is related or not, but a couple of months ago I unsuccessfully attempted to share a hotel's wired Internet connection over my wireless card. I may have hosed some settings or it could be unrelated.The "unknown interface" portion of the restart attempt is interesting but I don't know enough to fix it.
I'm using a Vaio TT, which seems to use an Intel 5100 WiFi chipset, and a Linksys WRT54G2 (firmwares 1.0.1 and 1.0.4), ubuntus 10.10 and 10.04.
Wifi works fine out of the box. However if the other vaio tt in our office (running windows 7) comes online, my laptop stops being able to make new connections. It WILL stay connected to chat servers, and downloads SOMETIMES continue to work. However all new HTTP requests / ssh connections / rdp connections / pings fail. The laptop still appears to be "connected" to the wifi network.
This may also happen after an undetermined amount of time without the extra vaio. It is not solved by reconnecting or rebooting. Once the extra vaio leaves the building, everything works fine again. This problem does not happen at all if I boot into windows.
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 upgraded to Ubuntu 10.4 on my Dell Inspiron 6400 yesterday (32-bit). Everything was running great, but when I turned it on today my wireless adapter is no longer working and the hardware switch doesn't do anything. It's working in Windows fine so it can't be the hardware.Here is some information:
Restarting the network with 'sudo /etc/init.d/networking restart' didn't work.I've tried Ubuntu several times before but usually there is one small issue which makes me go back to Windows. I love 10.4 so I hope I can get this working so I can stay on Ubuntu!
I upgraded from 9.04 to 10.04 then 10.10. Now my left mouse buttons doesnt work when I click the pplications menu. Sometimes it doesnt work at all. left or right click. This is very frustrating to say the least. I have seen a few posts that look similiar and have tried what they sugested, but it still doesnt work. I have tried different mice, but it is the same problem. I dont see any error msgs in any logs I look in. Im thinking my next step is to reinstall, which Im not too excited about.
Recently I have been having issues with wifi. I can connect for about an hour and then after that the computer stays connected to the network but wont allow me to go anywhere on the internet.
Like many others it seems, my wireless has stopped working since a recent upgrade The answer does not lie in analysis of logs, settings etc. but surely with those who did it - they should provide a fix. I cannot believe everyone expects each individual users to go into their own analysis of why this is no longer working as it is clearly widespread. I have been using Ubuntu for 18 months without this problem on the same dual-boot laptop, and it still works on Windows as before, only Ubuntu 10.4 has recently stopped my network card from working.
I need to know when this will be fixed. I have been embarrassed by promoting Ubuntu to many colleagues who now also cannot work at home on their wireless networks. Seriously disillusioned I may start looking for a more stable alternative to Windows.
WHat would cause an applette to stop working after performing an upgrade? there is one applette that would allow me to access a site that just stoped workign when i upgraded the distrubution
I just upgraded to 10.4 lts, and compiz stoped working. EDIT: lspci | grep VGA gives me:
Code: 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03) If I try to run it from terminal i get: Code: Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0".
I'm using Fedora 14, 64-bit. My wi-fi adapter is Intel 5100 AGN on a Lenovo laptop. The wi-fi router is Zyxel. From time to time, I'm getting a black message, that a kernel component has crashed (or something similar). Here are the error details:
In most cases, after that, I'm loosing the internet connection. I can't open any website, can't ping the router (which is my default gateway) and now it happened even without any error, which really pissed me off. Logging out and back in doesn't help, I need to make a full reboot to get back my internet connection.
Under Windows 7 everything is working fine and I'm not having any trouble with the internet connectivity! I had Fedora 11 32-bit before and it was also working normally!
Initially it was working fine after fedora 15 install.However recently it simply stops responding after a period of time.After reboot, sometimes it does repair itself but again stops working after some time.I'm not aware of any package updateperformed or configuration change that would have impacted it.And it does work intermittently as mentioned above
I have a Broadcom wireless card in my hp dv6500z laptop, I had it all working properly in FC9 thanks to bbfuller and his post on the subject. After I upgraded to FC11 I have been unable to get it to connect.
I can see my neighbor's sites and suppose I could see my own if the SSID was allowed to broadcast but I keep that turned off. I put in all of the setting, including the network security key, but it won't connect, then when I go back and look again, the security key is not even close to what I put in; it gets changed to a huge string of characters.
I redownloaded broadcom-wl-4.150.10.5.tar.bz2.tar and followed the instruction on the post once again but no luck, which, after I thought about it, was a waste of time because if I can see other's wireless, then the card must be working. I have tried using Network Manager and not using Network Manager and still no luck...
Im having problems with Ubuntu 10.04. My wireless disconnects frequently and firefox seems to stop working. it seems the connection times out sometimes when firefox stops. other times the connection just disconnects. When I was running 9.04 everything worked and nothing disconnected, so I know its not my computer.
My laptop is an IBM t40, 1.4 ghz, 2gig of ram.It does not seem to mater if Im using the wireless or the wired connection. The problem happens either way.does anyone have a solution for this?
I use a Kensington Wireless Netbook Mouse.It has worked well in Ubuntu 9.10 and 10.04.For some reason in 10.10 it works, but every now and again it sticks for a second or two. Sometimes the left button stops working.If I pull out the dongle for the mouse and put it back in my mouse works fine.
