Ubuntu Networking :: Loss Of Wireless After A Couple Of Hours
Mar 8, 2010
I have a hp dv3 laptop which dual boots Win7 and Ubuntu 9.1 64 bit. I have no issues with my wireless adapter in Win7, but I lose connection after a couple of hours in Ubuntu. When connection is lost it is not possible to view any wireless signals, the adapter is basically turned off. The only way to restore the connection is to reboot, then Ubuntu will again automatically connect to my WP2 encrypted router. My wireless adapter is a AR928X made by Atheros.
I am unsure if this is a hardware problem or a linux problem. My machine is only 3 months old so it is not the fan. I didn't have problems until recently, and after the latest kernel update it got worse - having to restart more frequently.
I do not experience the fan turning off in windows. I use thinkfan when I have to but it isn't a very good program for an every day basis. The fact I can force start the fan with thinkfan when it turns off leads me to believe it is a kernel issue.
i have a problem. when i changed from xp to linux mint 8, my speakers seem to just give up on me after about 2 hours of use. the only way i can fix them is to restart the computer.
this problem is quiet enoying, so i hope that somebody can help me tracking down this problem and find a solution. When i open vlc or exaile and queue a list of tracks, after playing some hours, the sound hangs and in the music player repeats the same 1 second audio part like a hickup, in video programs like vlc also the film freezes.
i have the latest libraries of gstreamer from packman installed and i also tried updating the pulseaudio libraries from multimedia repo. but the problem is still the same
I have a Dell 1545 laptop with ubuntu 9.1 32-bit installed (the 64-bit had a bug with the wireless drivers which is why I have not used it). Initially, the laptop worked well with the wireless (a sky router with WPA security) but now, the wireless signal drops after a couple of minutes of usage. I have to reboot the laptop or sometimes reboot the router as well to regain the wireless signal. I am using the Broadcom STA proprietary wireless driver.
I have an older dell inspiron 6400 as well with the same OS and driver and it works perfectly without any problems for hours / days.
I have a new Toshiba Satellite L450, and decided to run Ubuntu, which is new to me. I am running a 64 bit Karmic, and there is no driver that works. So, to make a long story short: a friend helped me get a driver on my Desktop, namely: rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz We had it working, but when I let in the first large batch up updates, it kicked the driver out. I found instructions, installed it again. I let in the next updates, and it kicked out again, and this time the instructions don't work. So, I have two sets of questions:
1. Will updates always undo my wireless? Are there certain updates I should avoid if I want the wireless to stay up and running? (I just assumed the thing to do is just get the updates -- though I am guilty of having no idea what they were about.)
2. Did the updates cause one of my instrucitons to no longer work, or need to be modified?
They were as follows:
sudo apt-get install build-essential cd ~/Desktop sudo tar -xvzf rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz That 'sudo tar -xvzf...' operation is the one that stops me. Is there something to change in that line? It goes on: cd rtl8192se_linux_2.6.0100.1012.2009_64bit

this worked the first time I tried it. I posted this earlier under 'hardware', and do not know how to get that post off, so I typed it here once I realized.
For most of today I had my internet connection dropping out on me intermittently. I assumed it was a provider issue, as it has been unreliable in the past. After it dropped out for good, and I could not print through network, I realised it was not a provider issue. All the other computers in the house were connected, including another ubuntu box. Only the MacBook Pro 5,5 was not able to connect. The network manager indicated I was connected to the network, throughout the whole time.
A number of restarts with the kernel I normally use (2.6.31-19) including one in recovery mode, yielded no change, but a restart with the 2.6.31-20 kernel resulted in connectivity. Finally, perhaps by chance, wireless started to work again on the 2.6.31-19 kernel, after I once booted into the Mac OS, and then back into Karmic. How I might go about diagnosing, obviously in hindsight, what happened? I suppose I should look in the log files, but I have no idea where exactly, and what to look for.
iwconfig shows that the bit rate is 130Mb/s and link quality is 98/100. I'm using the wcid network manager instead of defaul gnome one. I'm getting lots of packet loss and performance is very bad. The connection is practically unusable. I've tried installing the compat wireless backport package but that did not work at all.
The problem is I have a wireless Belkin router which I can connect to, but after being connected for a few minutes the net disappears (cuts from the router) and my laptop will have to reconnect again to the router for internet to work again. After a few minutes (or seconds in some cases) the connectivity loss will happen again over an over.
How to fix this problem or some things I can try, I've tried updating to two different firmwares, two different channels and resetting the router. The biggest problem I find is that this happens on both my laptop, another laptop in the house and also my tablet PC but doesn't happen on two other laptops in the house, I've also tested with windows 7 and Ubuntu with my laptop.
My laptop wireless card is Atheros AR9285 802.11b/g/n WiFi Adapter
I am running Slackware 13.0 on a old dell dimension 4500. The install went fine. sound worked, graphics where good. Everything was going perfect. until i worked on wireless.i have a realtek rtl8185 wireless chipset card. I got the wireless. Linux wireless driver. It worked on both Mint 5.0 and backtrack 4.0.so I untar the file. cd to the dir and type make then make install and reboot. like I have always done.
I was having to fight with wpa_gui and finally got it working but then it would go in and out on the connect and disconnect feature. so I tried using iwconfig. did not get muc luck with that either so i installed wicd and finally got a ip address after fighting with it would give me in a ping like 75% packet loss. so I read a lot of post and try to find stuff before I post. and while reading I learned that you guys normally ask for info on the hardware and software so here you go. but I will say first that I read about adjusting the mtu to fix packet loss, I showed some of the changes I made in it around the pings I know it is a mess I am sorry I tried to make it readable. if you need more information let me know. I cant get online using a web browser or if I can only for one or two pages. any help would be great. thank you.

I have a Dell Inspiron 6000 laptop running Fedora 12. Recently my wireless connection has begun dropping every few hours and not reconnecting. After trying for about 30-45 seconds, the WPA password prompt comes up but still doesn't connect.

Excited at seeing the new features in 10.04, I clicked the Upgrade button tonight. I am now really regretting it! Problems:
1. My screen resolution should be 1280x1024 but the System>Preferences>Monitors control panel only shows 1024x768.
I think I have onboard Realtek graphics. Do I need to install proprietary drivers? Everything worked fine out of the box with 9.10!
2. The sound isn't working. Again I think I have onboard Realtek sound, and again it used to work fine without any intervention from me...
3. Although on first startup wireless networking was working fine, I restarted to see if that would solve the display issue, and wireless networking stopped working too!
I have an RaLink wireless card.
When I used Grub to choose 2.6.31.20, I got some error messages at startup (e.g. mount couldn't mount /dev), but then it did eventually start up and the sound and wireless networking are working again. But the resolution is still not fixed. It is now offering 1152x864, which it didn't previously, but no 1280x1024 (my screen's native resolution).
I am recently trying to get a steady wireless connection running. I am currently using the default settings/driver Fedora 13 is stocked with. As my internet browsing is somewhat up and down in load times, I decided to check in a video game which is generally a good test for me. haha I am harshly spiking and cannot find the source of my problem so my guess is a driver issue.

It is is seemingly right, my Windows 7 harddrive works just fine, this is just one last of the few issues I'm having from fully formatting my winblows HD to use as Linux storage.
I cannot find any native AR5008 Linux Drivers for my card and it has been a frustrating day. I guess I'm not cut to be a network analyst just yet.

I switched to Ubuntu from Windows a few months ago and have had it all working fine since.
I turned on my system today and did some updates, then restarted but after the boot selection screen which I cant use as I have a USB keyboard the screen went to that purple/pink colour and froze for ages. Eventually my desktop appeared so I tried restarting it again and the same thing happened. Before from the boot selection to my desktop would only take 5 seconds or so but now it takes about 3 minutes.
Also since the updates I can't connect to my wireless network. I was using the Windows Wireless Networks software from the Ubuntu Software Centre, now when I try opening it manually it just hangs. I tried removing it and reinstalling it but still no joy.
I may have been too trusting with the updates so didn't read the list, I just updated and restarted and thats when the problems started.
I'm not quite sure what information you need but here are the bits from the System Monitor:
Release 11.04(natty) Kernel Linux 2.6.38-8-generic GNOME 2.32.1
On windows I would have considered myself an intermediate user but since switching to Ubuntu I feel like a beginner again although im learning fast.
Basically upon logging network manager will connect to my network, and most of the time it will only last 20 seconds or so before it disconnects and tries to reconnects, this tends to go on for quite a while. Logging off and logging on over and over worked once, for this post I opened pages between the 15 seconds that i was connected and after 20 minutes it has remained connected (every time it stays connected for longer than 5 minutes it will never disconnect again) I followed the HOWTO thread so forgive me if most of this information is useless

I have 3 Dell Precision M4400 machines. After getting updates yesterday or today, I get random network dropouts like crazy, on wired or wireless. On one machine I was able to turn off ipv6 in grub and reboot, and it works now. However on the other 2 machines, still have the same problems. All 3 are running 9.10 64 bit. Is there a way I can back out the updates so the network works again? Anyone else see this behavior after updates today?
Periodically, about 3 to 5 hours, Ubuntu disconnects from my wi-fi network and doesn't reconnect until I restart the router.This is an Ubuntu specific issue, since it doesn't happen when I boot into my Windows partition, and it doesn't happen to other computers on the network.
I have a minor Internet issue. I have a static IP address with the modem acting as a gateway only to my ISP. My Ubuntu server hosts my public IP address and I use pppoeconf to connect. Every 3 hours I lose Internet. I have wrote a short script to reconnect. I doubt that it is my ISP trying to renew that often.
Today my eth0 has intermittently shut down a couple of times without obvious cause from router or modem which appear normally lit. This happened a month or two ago soon after an update and them went away. I have unchecked ssh in the firewall settings as it is not needed but this has never been a problem. In the block of code there should be one attempt to graphically restart eth0.
I'm using Ubuntu 10.04 32 bits and a Realtek 8185 wireless card. The card worked perfectly fine with WPA for a long time in Windows 7, but on Ubuntu I'm having problems. Using it without installing anything else makes it work for a very short time. It disconnects after a while and I have no other choice but to restart the computer.
Using windows drivers and ndiswrapper doesn't work at all (in fact it makes things worse because it stops recognizing my card at all). Using the linux drivers from Realtek's website is what works the best so far. I had to compile them and install them. But it still disconnects after a few hours if I'm using WEP (and only after a few minutes if I'm using WPA). I looked at other people with 8185 problems in this forum but their solutions didn't work for me.
I am just starting my adventure into Ubuntu. After installing and configuring Shrew Soft in Ubuntu 10.04 64Bit, I am having some serious packet loss issues. The LAN is wireless, however the only packet loss I experience is over the tunnels. I have tried different algorithms, and it seems as I fiddle with the MTU client side, it clears a bit, but the best I have managed is 23% loss average.
F10 trying to key in static ip address. Have followed guidelines on turningoff NetworkManager and turning on network. i went to command line and did a couple of chkconfig things and entered ip address, with subnet. when i do ip addr show i see under eth0 inet 192.168.3.11/32 which is 255.255.255.0, i'm pretty sure. i do not see gateway. when i go to system/network get prompted to log into root, network config window opens. icheck eth0 and the subnet mask is 192.168.3.1, the gateway, which is in correctly, in the gateway slot, as well. i still can not ping to from my xp based multihomed router.
I'd like to find some sort of program which can tell me how much incoming data I've had in the last 24 hours. It goes by hours, not by days, but anything that's simple and that can display this will do. Is there any sort of program that does this? Something that would fit well with Ubuntu's style wouldn't hurt, but I'm not that worried about it as long as it does the job.
I got a new X201 which is running Ubuntu 10.04. While at home, everything is fine, at work, I encounter some issues with wireless. the signal cuts in and out repeatedly.Here's the output of ping. I set it to ping a server every 90 seconds, 10 times. So this is a snapshot of 15 minutes of network activity...
Code:

Also I tried this (from a 2 year old thread which was most relevant solution I could find):
Code:
Changing AVAHI_DAEMON_DETECT_LOCAL=1 to AVAHI_DAEMON_DETECT_LOCAL=0 in /etc/default/avahi-daemon has got rid of the irritating pop-up. Basically, every 5 minutes or so, for a solid 60 seconds or so I get no signal. I've tried updating the kernel, and doing apt-get remove avant-daemon, but still have problems.
PC running Ubuntu 10.04LTS, with a Virgin media modem NTL250 with a Buffalo Airstation Turbo G wireless router running Tomato Firmware v1.27.1798.The router is is used by a Internet radio, a wii (both full time) and a nokia N86 mobile and a PSP (used occasionally). The PC is connected by a network cable to the router.Now, when the modem is plugged directly into PC i get 6 to 8 Mbs download speed. When I go modem to router to pc the speed drops down to 512 to 824Kbps. Speeds were obtained off of broadband.co.uk speed tester.
