AW: changing AP manual is unstable

[Henrik Gütle]

Nope. It even seems to getting more unstable :-(

What I'm trying to do, is to collect signal strength and other
information from 3 different AP's. Since the iwlist wlan0 scan doesn't
return the RSSI, my idea was to connect to each AP in turn and then
readout the corresponding statistics. But since changing AP is so
unstable, I wondered if someone's got another idea?

henrik
i get that same error sometimes too, you need to reset the card. then
try to connect. also try:

iwpriv wlan0 dump 0

- will stop the TXEXC messages from coming.

good luck ,

Nope that didn't change a thing:

wlan0: TXEXC - status=0x0004 ([Discon]) tx_control=000c
   retry_count=0 tx_rate=0 fc=0x0108 (Data::0 ToDS)
   A1=44:44:44:44:44:44 A2=00:06:25:16:c3:73 A3=ff:ff:ff:ff:ff:ff
A4=00:00:00:
00:00:00
wlan0: Trying to join BSSID XX:XX:XX:XX:XX:XX
wlan0: LinkStatus=6 (Association failed)
wlan0: LinkStatus: BSSID=44:44:44:44:44:44
