Comment 42 for bug 630748

I'm thoroughly confused. Yesterday I enabled N on my WAP and the previously rock solid wireless connection for my Intel 5300 equipped T500 became very unstable. Several times the connection dropped to the point where network-manager presented me with the password page. At other times it would drop and recover in a few seconds without intervention. I found this bug report while trying to resolve the problem. My T500 is still running 10.04.

I added the file /etc/modprobe.d/intel-5300-iwlagn-disable11n.conf with contents
[code]options iwlagn 11n_disable=1[/code]
 and executed:
[code]sudo rmmod -f iwlagn
sudo modprobe iwlagn[/code]
and the card is still using N. Next I tried:
[code]sudo rmmod -f iwlagn
sudo modprobe iwlagn 11n_disable=1[/code]
Still running N and still unstable, though it did settle down and remained connected (or at least did not give up and ask for the password) overnight.

I have found information scattered throughout forum posts but have not seen any that seem to have better info than what's in this bug report and that seems less than complete. Questions I have:

Is 10.04 subject to the Intel firmware problem (or should I be looking elsewhere for a solution to my problem.)

Is the syntax I'm using to disable N correct? Is that option not supported by the module in 10.04?

Is there there better information on this bug?

thanks,
hank
