[Bug 548992] Re: Wireless connection frequently drops [deauthenticating by local choice (reason=3)]

 

Further to my comment above, this is the content from end of
/var/log/daemon.log. It appears to be timing out on a DHCP request.
Since my AP hasn't changed in years, it must be a change at the Ubuntu
end that has produced this issue. Since the last update, my workaround
no longer works around, so am a bit stuck. I tried the disabling IPV6 on
the command line but this hasn't helped.
