Description Aidan Skinner 2008-06-28 15:35:47 EDT
Description of problem

My 802.11g network only achieves speeds of around 80-250kb/s under fedora,
instead of something more reasonable. This is quite frustrating.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Connect to wlan 
2. scp file
3. watch molasses-like transfer speeds
Actual results:
175MB file takes upwards of half an hour to transfer

Expected results:
175MB file takes a couple of minutes at most

Additional info:
this seems to affect both my Thinkpad z61 (Intel PRO/Wireless 3945ABG) and my
t41 (atheros AR5212). GigE speeds are roughly what you'd expect.
Comment 1 Aidan Skinner 2008-08-12 16:57:13 EDT
So, this seems to be dependent on network quality, in that if I sit right next to my AP, it works happily, but if I move away then it starts to suffer badly. NetworkManager reports a much lower connection quality, which never improves. Maybe there's some low water mark effect going on?

(an eeepc and a linksys wrt54g running as a wireless bridge do not show significantly impaired connectivity in these locations)
Comment 2 Chuck Ebbert 2008-09-22 17:25:04 EDT
Is it any better in
Comment 3 Aidan Skinner 2008-09-29 15:26:51 EDT
Better, but not fixed. Now I get around 1.2MB/s compared to 2.5MB/s with the wrt54g bridge. It was around 300KB/s before.
Comment 4 Aidan Skinner 2008-10-05 13:00:26 EDT
And it's back to rubbish again in :'(

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  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bug reports from releases that are no longer maintained.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 '9'.

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 9'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 9 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: 
Comment 6 Bug Zapper 2009-07-14 11:51:51 EDT
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
