Any wifi protocol savvy people who can explain this:
iwconfig wlan0
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
What I've observed is[1] ( No activity on wlan0 ) Bit Rate is 1MB/s
[1]-----------------
iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:"cisco"
Mode:Managed Frequency:2.447 GHz Access Point:
00:25:9C:89:DX:FC
Bit Rate=1 Mb/s Tx-Power=15 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=68/70 Signal level=-42 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:108 Invalid misc:4 Missed beacon:0
Sending some data through wlan0 ( may be ping yahoo.com ) Bit Rate is
150MB/s
[2]-------------
iwconfig wlan0
wlan0 IEEE 802.11abgn ESSID:"cisco"
Mode:Managed Frequency:2.447 GHz Access Point:
00:25:9C:89:DX:FC

May be this can clear the matter :-)
I think your card has automatic power reduction mode
when idle - I had a card like that that refused to honor
iwconfig wlan0 power off
So, I got rid of it - because it had such a long lag time
of nearly half a minute to get back up to full speed.
But the current situation is that it stays fixed at 18mbps
whether active or not.
