Description Piotr 2009-11-02 14:07:57 UTC
Description of problem:
I can connect normally to my wifi router (Linksys WRT 120N with wpa2 encryption enabled and Thinkpad T60 with Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)). And the network works fine... till I start downloading and uploading fast torrent files. After some time (sometimes 5 minutes sometimes a couple off hours) the connection hangs, even router doesn't answer pings. But NetworkManager says that the connection is fine. I have to click on my network to reconnect. Sometimes during manual reconnection it displays window with wpa password and sometimes it just connects without any additional actions. In some rare cases NetworkManager recognizes that the connection is lost and then it displays window with wpa password.

Version-Release number of selected component (if applicable):
2.6.30.9-90.fc11.i586 and older


How reproducible:
I've noticed it only during fast downloads and uploads of torrent files. I've impression that it has something to do with uplaod speed and number off connections. When I limit upload speed in torrent client to 50KBps it hangs much rarely then I don't set any limit

Steps to Reproduce:
1. Connect to router
2. Start downloading some torrent files that are fast (many seaders)
3. Wait until the network hangs - the download stops, no ping answers, but the connection is active 
  
Actual results:
The wifi connection hangs

Expected results:
Stable, non-hanging wifi connection

Additional info:
/var/log/messages doesn't say anything interesting.
I haven't been able to hang the connection in any other way than bittorrent

For several days I'm testing fedora 12 beta with 2.6.31.5-127.fc12.x86_64 kernel and it's much better. I had only a few (two maybe three) visible disconnects since then. I've noticed that it still disconnects, but usually it reconnects without any user action.
I'm not sure what I should do with status off this bug - so I'll leave it to You ;)

Piotr

Comment 2 Bug Zapper 2010-04-28 11:03:26 UTC
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '11'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 11's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 11 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Hi, I'm still having the same problem on fedora 13 beta. If I am for example downloading updates, even if it shows the connection is still active the download will just block for about another 10 second to start again and drop again and start again..

Comment 4 Bug Zapper 2010-06-28 15:22:14 UTC
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
