Comment (by [EMAIL PROTECTED]):
i too was experiencing this issue. Upon upgrading to lasted trunk release
from SVN, the problem appears to be resolved. I can switch channel after
creating the AP using wlanconfig. However, even though iwconfig reports
the AP interface is using the channel requested, when I bring up
netstumber on another machine, it reports that the access point is
scrolling through all channels, eg channel hopping. using athchns to try
to combat this results in the system lockup scenario coming back.
Also worthy of note, when wlanconfig created ath0 and confirms ath0
creation, udev moves that device to ath1 immediately (per dmesg). Im not
sure why (Ubuntu 8.04), as that doesnt seem to happen when ath0 is in sta
mode.
Now my AP appears running on ath1, but channel hopping. I try to create
station and get the old "I/O error" which I used to get when not supplying
"nosbeacon", however in the current driver "nosbeacon" is depreciated, so
im not sure why I get "I/o error"
