	Hi Sam!

 Sam> I do not understand what "bad connectivity" means.  

I'm not a native speaker so I've apparently used a wrong term, I apologize
for the confusion. Instead I should've probably said "low signal strength".

Here it is:

dmesg:

<Atheros 5212> mem 0xa8400000-0xa840ffff irq 11 at device 2.0 on pci4
ath0: [GIANT-LOCKED]
ath0: Ethernet address: 00:14:a4:80:f6:74
mac 5.9 phy 4.3 radio 3.6

sysctl -a | grep ath | grep hal:

hw.ath.hal.version: 0.9.16.16
hw.ath.hal.dma_brt: 2
hw.ath.hal.sw_brt: 10
hw.ath.hal.swba_backoff: 0

Output after wlandebug +debug scan is too large to be quoted on the list,
so please take a look here: http://www.karasik.eu.org/misc/ath0.html ,
probably you can find anything suspicious?
