Ubuntu Networking :: Acer 5520 Wireless Randomly Stops Working
Apr 28, 2010
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 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:

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?

Not sure if I've listed the specs of this machine before, so I'll do it again. 'm running an HP Pavilion 760n with 512MB of RAM and (I think?) a Pentium III processor... not sure on that one right now. It's currently running a laptop version of Ubuntu 10.04.I went to log into my online classes tonight only to find that the computer wasn't responding at all. I did a hot shutdown and restarted it, and now the system isn't detecting the internet connection at all. It should be noted that the connection was working perfectly fine earlier today, perhaps 6 or 7 hours ago.I know it's something to do with my computer and not my router, as I'm on my wireless network from a Windows 7 laptop and it's connecting just fine.
In viewing another thread,..lems+-wireless, I found a bunch of commands that it was said would be helpful diagnosing this issue. That said, below is the output of all the commands that I could think of.
Sudo ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:e0:18:5c:45:7a
inet addr:192.168.2.1 Bcast:192.168.2.255 Mask:255.255.255.0

I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.

It has to be an update or something that cause this. I've done nothing differently from the other days I use this laptop. I have to keep relogging every now and then because the sound stopped working. I can turn the volume up but pidginrhythmbox, nothing makes noise anymore. it's random...it just started happening today and this is the second time the music went out. anyone have any idea of how to stop this from happening in the future?

I'm using Ubuntu 10.04 since several months and I randomly have problems with the keyboard (PS2). Maybe 2-4 times per week the keyboard stops working all in a sudden. The symptoms related to this can be- the keyboard simply does not react any more to key press- during typing the keyboard gets crazy and fills the lines with the last typed character- opened windows move to the left when touching them at the top bar, keyboard does not react any more. When clicking on a panel menu the focus line is running permanently quickly through all items, and it's practically impossible to click on any of those (so even shutdown is difficult to achieve, and I might need to use a hard reset).
In nearly all cases the problem only disappears after reboot, just very rarely a logout is sufficient to get the keyboard working again. I googled for similar problems and found quite some people having problems with keyboard (and/or mouse) not working correctly under Ubuntu, but I have not stumbled over a similar error description as I have.Just some config parameters on my box: amd64, XOrg uses an Nvidia driver, 3D and Compiz are activated

Routinely, while I'm working on my laptop, the sound will randomly stop working and I can only get it back by rebooting. I can't seem to find any sort of pattern to what gets it to stop working, but I do have the following programs almost always running: Evolution, Chrome, Transmission, and Pidgin. I usually notice it first when Pidgin stops beeping when I receive IMs.
In the messages log I see lots of messages like this when the audio stops working:
Code:
Nov 9 10:35:04 jbirdjavi-l-u pulseaudio[2031]: sink-input.c: Failed to create sink input: sink is suspended.
Nov 9 10:35:42 jbirdjavi-l-u pulseaudio[2031]: last message repeated 7 times

On a whim vsftpd seems to stop working randomly and any attempted connection times out while waiting for the welcome message.It'll take a couple reboots and a couple "sudo service vsftpd restart" 's and it'll eventually start working again.AFIIK everything is at the most currant version. It just started doing this a few weeks ago.Here is my config file:

I am asking in the wrong place or anything like that, I tried to understand the Tutorials, but I am only human Oh and I am not a native speaker of English, So I also apologize for that...Okay enough apologizing, I will assume that you are all nice people and wouldn't have made fun of my stupidity anywayAs I said I am new to Linux and also to my PC. I bought it a couple of weeks ago and I tried to install Windows on it, but it was displayed in only 16 colors ( I assume this is not connected to my current problem but it might be...) and I couldn't fix that so I installed Ubuntu 10.4.something( It asked me if I wanted to upgrade to the newest version...) . Since then I have been really happy, I only had minor problem with the chat software but after I googled it I found a solution and I even used the console for the first time in my life.
The problem with the chat software is back now, but I don't care about that.My Computer randomly stops working and the screen goes all weird. It switches between a mix of white and black bars, something really colorful and a black screen with text ( I have the feeling it's different text every time) I am not sure what happens after that, because I always turn it off and restart it. It won't react to anything when it is in this weird mode. I don't think there are any special situations in which it happens and I can't reproduce it, it just happens when I don't want it to happen. A friend who uses Linux said it might be a temperature problem, he only knew what I just told you. I am not sure if there is a connection between the time the computer has been on and the time it shuts off...I really like Linux and I would love to use it without ith when I said that I got my PC new ( it was used though) I was trying to say that I don't know whether this is a Ubuntu problem or not

This happens randomly after a reboot: I can move the mouse cursor and it works perfectly only on the Unity sidebar or whatever it's called. I can fire up applications, but once they're up they completely ignore any clicks or mouse movements (the main menu does not appear on the top bar if I move the cursor in the location that usually makes it appear). They only recognise a click on the close/iconize/maximize buttons.
The mouse works: as I said I can move the cursor and it recognises clicks on the sidebar and the window control buttons; plus, it's connected via a KVM switch both to the Linux box and to a Windows box (from which I'm writing this) and in Windows perfectly.The pattern used to be this: usually while running Firefox, the mouse and keyboard stop responding, and sometimes the whole desktop graphics become corrupted. I can Alt+F1 and go to a text-mode console, but nothing short of a reboot "fixes" things. After the reboot, about two times out of five everything works, three times out of five I get the situation described above.
For the last few hours or so, however, no amount of rebooting and sacrificing goats to the gods protecting sociopaths and Linux software developers have been able to restore mouse functionality. I click on my username on the login windowhere it works perfectly), enter the password and then only the Unity sidebar works: again, the mouse cursor moves, only clicks (right and left) are ignored, as are hotspots. In ubuntu classic there is no place where I can click and launch applications, btw - once I get in I'm basically blocked and can't do anything

This bug has been around for years now?!? Surely this can be fixed by now, would somebody please feel this very common issue. I've installed Ubuntu 11.04 on my Acer Aspire One 110AB netbook and everything seems to work fine except the wireless - I can connect via ethernet no problem.
While the wireless can scan for networks - it seems them but they seem to be rather weak signals and also no matter never connect UNLESS I turn off ALL WEP/WPA security clearly not an option.

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 had UBR installed and working fine for a month or so, wireless and everything. Then I did a clean re-install while trying to add WinXP to half of my drive.Anyway, with the new install, my wireless chip (BCM4312 802.11b/g) isn't switching on at all. I've tried installing the Broadcom driver that appears when I run Hardware Drivers, but that doesn't help.With the old install, the wireless switch and indicator light on the front of the netbook worked, now nothing.
Output from lshw -C network is:
*-network

product: BCM4312 802.11b/g

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 have a wireless network using this driver:
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'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 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.

I have installed Fedora 12 on my laptop and subsequently spent most of the day trying to get the wireless connection to work. Looks like I am not alone with Wireless issues Through searching and reading today I think the problem lies with the fact that the wireless on/off switch is not working. Under Windows, when I press the wifi toggle switch it starts flashing orange. I haven't managed to get it to do anything under Fedora.

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.

in compliance with bonekracker's advice, i have reposted my SOS. i have the result of the outputs of the commands for ifconfig, iwconfig, and etc i have uploaded it in the file output.doc. i hope this would be helpful in debugging my problem.but before that, i do notice that if i click on the icon for the Network Manager, the Wireless networks is set to 'wireless disabled'. maybe if i can make it turn on, my wireless problem will be solved.. its just that i even if i move the switch for the wifi, it still wouldn't turn on.

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:
Package: kernel
Latest Crash:Sun 20 Feb 2011 04:27:54 PM
Command: not_applicable
Reason: WARNING: at net/wireless/core.c:633 wdev_cleanup_work+0x52/0xbd [cfg80211]()
Comment: None
Bug Reports:
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!
