Hi,
Same annoying problem here on a new desktop with a newly installed Ubuntu 8.04
(details below).
When I boot, the network comes up without a problem, but it is quite slow, as
compared with my wireless laptop (factor 5-10 slower). After some time
(variable duration) suddenly the connection is dropped and the message "[
1612.220846] wlan0: No ProbeResp from current AP 00:18:4d:36:bc:c5 - assume out
of range" appears in dmesg. When I stop the network and restart it again the
connection is reestablished.
Any options to get rid of this bug?
Thanks
Mike
