Ubuntu Networking :: Wireless Starts And Stops And Starts And Stops?
Feb 10, 2010
Sometime after I upgraded to ubuntu 9.10 I've been having trouble with my wireless network connection.It will usually log on to the network, then disconnect a shortly after. Then try to connect again, usually successfully, then it cuts off again. Then connects again, then disconnects. FWIW, ubuntu 9.10 works on a different machine pretty consistently, so I don't think its a problem with the router.
I have a problem with my wlan connection. it works for few seconds, then stops for few seconds and then starts again (without interaction from my side). I run Ubuntu 10.4 Lucid. The issue started few days ago. Using ethernet, there is no problem. The problem does not exist with other computers i have, there wifi and internet work continuously and flawless. I ping my wlan router. one sees that connection to the wlan router starts and stops every few seconds... (of course, internet connection then behaves analogous)

I have a small network of an Ubuntu server 10.4 , Debian server, Win XP, and an ubuntu desktop 10.4. I have configured a DNS server and DHCP server successfully on my ubuntu server, also a slave DNS server on Debian. I recently configured apache2 as part of LAMP on ubuntu server, but when I type my ServerName in the URL of my Win XP browser, I get this response: The webpage "mansour.net" cannot be found DNS error occurred. Server cannot be found. The link may be broken.
I have an A Record in my DNS zone file for mansour.net and have that as my ServerName in apache2 Definition file, but I don't know why it is not working. I am trying to learn to install and configure various servers on ubuntu.
My system: Slackware 13.0, 512MB RAM, x86 This is the webcam I'm trying to get working:

When I plug the webcam in (usb), the led starts to shine, indicating that it is filming. When I use a program (XSane for example) and click the 'scan' button, the led turns off! It seems that the cam works when it shouldn't, and vice versa.
I tried to install Ubuntu netbook remix Lucid on a Lenovo IdeaPad netbook with an Intel Atom processor and a SSD HD 4 GB and a SATA HDD of 160 GB. The installation starts normally, but stops on step 3 of 7, where I choose my keyboard layer...it never passes on to step 4 of 7. I must mention that I had a corrupted installation of Windows XP running on it...I made an USB bootable disk, and everything goes fine untill step 3 of 7.
A friend of mine has asked me to install Ubuntu for a long time. Today I set up his partitions with Lucid LiveCD and GParted.
However, the LiveCd throws an error that makes me hesitant to continue.
If I boot a LiveCD on my computer I get a question meaning "run Live or install?"
This question does not appear on my friends computer. The first thing you see (about 2 min after boot) is an alertpanel saying something like "The installer encountered an unrecoverable error. We will now set up a desktop environment so you can investigate the problem." After that the normal Lucid (Live) desktop appears and functions well, as far as I can understand.
Sorry for not being able to give more data about my friends system. It is a stationary computer about 2 yrs old, running XP. I can't really make investigations on his system either. I had hoped to go there next time and just install Lucid.
Maybe one should try the alternate installer, but my friend just got used to the LiveCD and I would therefore like to use the LiveCD.
I don't understand why it seems to start installation by itself.
Most of all. I wonder if it is a good idea to run the installation from the desktop icon? Maybe it will encounter the same error that the LiveCd seems to encounter at startup?
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'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.
I am trying to maintain another computer that runs Ubuntu, and everything seems to be running smoothly except for one thing: the wireless. Due to distance issues, I cant use a cord, but the computer is close enough to get a signal. am using a Netgear wnda3100 wireless usb adapter. I installed Ubuntu on the computer because I heard that the device was supported in Ubuntu, and it wast after a while, the adapter is no longer recognized. I have had to reinstall multiple times, and I'm no longer in the mood to reinstall. Does anyone on the UF know hwo to fix this
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.
I am having a problem where when i connect to a wireless network at school the internet works for maybe about 30 seconds but then stops. It still says connected but i cant get to internet websites Running Ubuntu Karmic 9.10 Installed "inside" windows School has multiple routers is that a problem? all have same essid Can connect to wirelesss at home flawlessly.
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.
My problem is that my wireless network traffic sometimes just stop.Like when I tries to update my system, update NetBeans or just download using Uget. I have no clue on what's wrong,Here is my system info:
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 used to use Ubuntu 10.04. Never had this problem. I went back to Windows 7 and then came back to Ubuntu, and 10.04.1 was released. After some usage of wireless internet, it disconnects from the access point, and phy0 has 100% usage. [URL].. I'm not the only one with the problem. I downgraded to 9.10, and haven't had that problem since the downgrade.
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.
~$ 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.
I have two laptops here, a Lenovo T510 and a Lenovo Ideapdad S12, both running Fedora 13 with KDE4. On the T510 wireless worked out of the box and is enabled when I boot it, on the S12 it's not. I have the wl driver installed but every time I boot the laptop wireless is disabled in knetworkmanager. I have to manually enabled it, then wait a few seconds until it establishes a connection to my already configured wireless networks.
I have a Microsoft Wireless Keyboard 3000 v2 and Microsoft Explorer Mouse Model 1362. The biggest issue I have right now is with the keyboard. The keyboard will start cutting out and not responding to keys. As soon as the cpu load drops then all is well. I have a PS2 keyboard that I keep plugged in just in case the load stays high and I need to type something. The mouse and the keyboard have seperate usb dongles, and when the keyboard is having issues the mouse is still working great. This tells me that either the USB radio for the keyboard gets turned off, or that something on my machine is weird. I have seen the EXACT same behaviour on 32bit and 64bit linux distros.
CPU: AMD X3 720 oc'ed to 3.22GHZ MOBO: Biostar RAM: 8GB Video: HIS ATI 4890 (using FGLRX) HD: Samsung 1TB 7200RPM drive OS: Ubuntu 10.10 (tested also with Fedora 14, OpenSUSE 11.3)
Note: it happens with very little load and high load. Of course high load it happens all the time.
