Rapidly declining wireless performance Fedora 16
I installed Fedora 16 (64 bit) on my ASUS G74S laptop (Intel i7 cpu, Atheros AR9002WB-1NG card). When I connect to my wireless system at work, I have no problem connecting, and things are initially great. But then I have increasing delays and dropped packets, to the point that, after about 15 minutes, I'll have four or five second delays in things like keystrokes with ssh (wireshark gives an ACK round trip time of up to 10 seconds). There will be occasional bursts of good connection that last up to a minute, but they become fewer and further between. Then, after about 40 mins, almost no packets get through. If I power cycle the machine, the pattern repeats (though simply disconnecting and reconnecting doesn't change where I am in this pattern).
Using a VPN out and using an external public DNS don't change things.
I had Mint installed prior to this, and it didn't seem to have the problem, either (though I uninstalled it when I installed Fedora, so I can't test it now.
This is dual-boot machine, and *none* of this happens on the Win 7 side of things. On the Win 7 side, I get good, uninterrupted connection.
Anyone else experiencing this?
