Public bug reported:
I have been having problems with my wireless on Ubuntu 8.10 and it has
never really worked right from the beginning and it has now been a few
months. I have tried a number of fixes from launchpad and none have
worked well.
Currently the wireless keeps dropping out. Sometimes I can disable and
then enable wireless and it comes back. Other times it will not even be
able to scan for wireless networks (As seen from the Network Manager
applet not being able to find any surrounding networks). In such cases,
I have to suspend the laptop and restart and mess around with
disable/enable wireless till it finds my home network again.
My home network is setup with 2 access points (1 airport extreme and 1
airport express). My laptop a thinkpad X300 has the intel 4965 wireless
card. My Mac and other windows machines do not seem to have the same
issues.
After some investigation, it appears that the error occurs when the
laptop is roaming from one access point to the other.
