Platform: Intel Pentium M (Dell D610 laptop),
Ubuntu Feisty (upgraded from Edgy upgraded from Dapper,
originally installed as Breezy)
wpasupplicant 0.5.7-0ubuntu2
network-manager 0.6.4-6ubuntu7
network-manager-gnome 0.6.4-6ubuntu7
linux-image-2.6.20-15-386 2.6.20-15.27
When I first upgraded to Feisty I tried connecting to my WEP protected
AP, and immediately succeeded. Later I've successfully (for the first
time) connected to a WPA protected AP at work.
But now the laptop no longer succeeds in connecting to my home (WEP
protected) AP. According to the dhclient logs it believes that it
doesn't get any DHCPOFFERS (though the logs on the DHCP server says
it's received a DHCPDISCOVER and sent a DHCPOFFER), retries two times
and gives up, and then network-manager successfully (and unintentioned
by me) connects to an open WLAN in the neighbourhood, with a much
weaker signal (the laptop is 30cm from my own AP when doing the
tests).
According to the logs in the AP the laptop has connected. And
according to the logs from the DHCP server, a NIC with the MAC of the
broadcom WLAN card has been given a DHCPOFFER (but has never returned
a DHCPACK).
In earlier OS incarnations, both using first ndiswrapper, and later
bcm43xx, I've seen this kind of flaky behaviour, but a shutdown,
followed by a reboot has usually cleared them up.
Any clues as to where I could start digging for clues, and workarounds
I could try, are highly appreciated.
Thanx!
