2007/5/9, Larry Finger <[EMAIL PROTECTED]>:
There are some problems with bcm43xx in a crowded environment; however, I think your problems are with signal strength. The iwconfig log shows only very low signal levels. I see that you are using 2.6.21. Have you patched bcm43xx? If not, that will help some. In addition, your school has designed your networks badly. Channels 9 and 13 interfere with each other. If they are going to put all their AP's on only 2 channels, they should use 8 and 13.
Unfortunately channels of APs didn't change. I tested this network again, using 2.6.22-rc2-git7-20-default and I was not able to connect. I made a small log of /var/log/messages, maybe it contains some usefully info? Ah, and one more fact. I think I have some problems with iwlist now: acer:/home/zajec # iwlist scan lo Interface doesn't support scanning. irda0 Interface doesn't support scanning. eth0 Interface doesn't support scanning. Warning: Driver for device wlan0 has been compiled with version 22 of Wireless Extension, while this program supports up to version 21. Some things may be broken... wlan0 Scan completed : But on the other hand I can connect to network in 3 not crowded env without problems... -- Rafał Miłecki
