I recently installed Fedora 16 on my laptop (ASUS G74S) that has an Atheros AR9002WB-1NG wireless card. It works fine with my home wireless system, but it doesn’t play well with the big router at work. It finds and attaches to the wireless system fine, and I get good throughput for about 15 mins, but then it starts dropping packets and getting delays. Wireshark shows up to 10 second for round trips on ACKs. I thought it was the router’s problem, but this is a dual boot machine, and it doesn’t happen on the Win 7 side. In addition, I have a USB wireless adapter (ALFA) that I can plug in and have no problems with.
This seems to be something specific to this card and this router — it doesn’t happen on my home network, and it hasn’t happened a couple of hotels I’ve stayed at. I plan to install Mageia 2 when in comes out, and I’ll see if that changes things, but I’m beginning to suspect that it’s a driver issue. Fedora recognized the card as an Atheros 9285.
UPDATE: This is fixed in the 3.3.4-3.fc16.x86_64 kernel, or maybe the update just before it. Thanks, Fedora team!
