User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.0.4-1.3.1 Firefox/1.0.4

Description of problem:
After upgrading to kernel 2.6.11-1.35_FC3 I was unable to obtain IP-address.  Loading with the previous kernel made everything work as normal.

A workaround was found in the Fedora-list:

Try deleting the CHANNEL line (or comment it out) in the ifcfg file.  I
have experienced a problem with ipw2200bg chipset where that appears to
be a possible fix.  Was able to see the access points but the card was
never able to establish a connection and get an IP address.

Suspect this points to a fundamental flaw in how the wireless cards are
handled by the system.

How reproducible:

Steps to Reproduce:
1. boot FC3 with kernel 2.6.11-1.35_FC3 without commenting out CHANNEL in in ifcfg

Actual Results:  I was unable to obtain IP-address from the router, however, kwifimanager showed that I had contact with it.

Expected Results:  I should have received an IP-address.

Comment 1 Dave Jones 2005-06-27 21:37:35 UTC
There were no IPW changes in the last kernel update (nor have there been for
some time in FC3).  Additionally, this sounds more like a configuration problem
than a driver bug.

Comment 2 Truls Gulbrandsen 2005-06-28 18:42:45 UTC
Please tell me, how can this be a configuration problem when everything works
using kernel 2.6.11-1.27_FC3 but fails using kernel 2.6.11-1.35_FC3 without any
other changes?

Does applying the work-around, commenting out the CHANNEL line, have any
negative consequence to my system?


Comment 3 Harald Hoyer 2005-06-29 12:06:34 UTC
This seems to be a change within the driver... 
If this behaviour is considered standard, then 
$ rpm -qf /etc/sysconfig/network-scripts/ifup-wireless

should be corrected

Comment 4 Dave Jones 2005-07-05 19:37:45 UTC
See comment #1.

"There were no IPW changes in the last kernel update"

Comment 5 Bill Nottingham 2005-07-05 20:23:05 UTC
If channel is not needed, then it probably shouldn't be in the config file; why
was it specified beforehand?

Comment 7 Bill Nottingham 2007-09-18 19:26:02 UTC
Closing this bug - FC3 is older and no longer supported. Please reopen if this
persists on a current release. Apologies for the delay.
