Comment 57 for bug 630748

Just wanted to add that intel will not be fixing this issue for "legacy devices", including the 4965agn:

"> In reference to the splitting of the iwlagn driver with a legacy branch, will
> the 4965agn get a similar fix. These network cards have similar issues,

It will be very difficult to add the same firmware fix for legacy devices
including 4965. I am really sorry about it.

Thanks
