Hello,

I have this wireless card:

It's a D-Link AirPlus DWL-G650 PCMCIA card. When using it in netbsd 
signal is very bad. Laptop and access-point are in the same room. Not to 
mention that booting windows and checking signal strength shows 98%. 
Here is wlanctl output:

ath0: mac 00:0f:3d:af:15:94 bss 00:0f:3d:af:15:94

My laptop has also an integrated iwi card that works fine:

         assoc-id 0 assoc-failed 0 inactivity 0s
         rssi 226 txseq 0 rxseq 3847


I saw in Windows that this card has 3 modes of operation regarding power 
consumption: low, medium and high and I beleive the problem it's somehow 
  related to this.

Any hints ?
Thanks,
Mihai
