Any wifi protocol savvy people who can explain this:
iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:"Private"

00:AA:BB:CC:DD:EE
Bit Rate=18 Mb/s Tx-Power=27 dBm

Power Management:off

The access point is a 54G wifi gateway and router.
My wifi card is the Atheros AR5008 which is an 802.11n card.
How could the bit rate be restricted to 18Mb/s??
Is this a problem with the ath9k driver or the wext driver?
PS: I did not have the issue until installing FC16. This
problem was absent in FC14.
I thought wifi adjusts the data rate on the fly based on how strong
the signal is. Try moving the laptop closer to the router, at least
just to see if the rate goes up...
No difference!!
Stuck at 18mb/s
By the way: I changed wifi interface on my machine to an rtl8187
and still iwconfig reports 18mb/s, with full signal quality at 70/70
!!!

Hm, you're right - the quality is out of 70 and the rate is really
low.. here's mine:
wlan0 IEEE 802.11abgn ESSID:"Redacted"

00:14:D1:C4:4C:3F

Maybe it's because I'm also connected over ethernet, so wifi is not
being used, so it's in powersaving mode of some kind..?
See if your rate goes up/down if you're actively transferring a bunch
of data.
My rate remains constant at 18mb/s
