Crashing wireless and stuff blocked for too long

Postby Kerr on Sun Apr 21, 2013 11:52 am

Hi all.

Long story short, I bought a USB wireless card for my desktop computer. It has been working well until recently. Basically, it randomly crashes in an odd way. It suddenly goes to 100% connection strength, but I cant do anything network related at all. And the programs that are using the internet wont work either. Firefox wont shut down properly when it happens. Restarting the computer helps. I have seen some interesting stuff in the syslog file.
NetworkManager[741]: <info> (wlan0): device state change: activated -> unavailable (reason 'none') [100 20 0]
NetworkManager[741]: <info> (wlan0): deactivating device (reason 'none') [0]
NetworkManager[741]: <info> (wlan0): canceled DHCP transaction, DHCP client pid 1440
kernel: [ 1260.140609] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
kernel: [ 1440.664038] INFO: task NetworkManager:741 blocked for more than 120 seconds.

Fact is, there is a lot of the last line after that point.
INFO: task xxx blocked for more than 120 seconds

If I try and access network settings I also get an error message of some kind, and then no network is listed. Not the wireless, nor the wired. I see a "network proxy" thing, but nothing else. The problem tends to occur when I watch youtube, but I havent experienced it enough to know if thats the cause or if its something else.

I have had a few issues with this network before, on my laptop. It really doesnt like my laptop at times and randomly throws it out. Sometimes the wireless router had to be restarted to get it to work again. Dont know if that issue is related to my current problems, though.

I am running 64-bit Nadia. The wireless network thing is a "tp-link wireless n usb adapter" (dont know if thats the name, its just what the box says in large letters).

Take care,
Kerr.

A new clue. I tried to restart the router this time and it worked. Had to pull out the usb wireless thing and then put it back in first, though. Could it be that when the router decides to kicks me out, the driver crashes or something like that?
