Public bug reported:
Whenever I attempt to connect via Wifi, my connection remains up for 30
seconds at most before disconnecting.
(I can successfully browse for the few seconds it remains connected.)
If I have it set to automatically connect, it "connects" then "drops"
repeatedly.
Other machines on network WPA-AES do not have this issue.
Using network-manager and haven't instead installed wicd *yet*.
Hopefully this can be resolved first. =)

Note:
--------
- ifupdown was installed and handling eth0 (eth0 was not detected by
network-manager during installation).
- ifupdown is handling eth0 properly when ethernet cord connected.
- wlan device losing connection not a signal strength issue (same room
as the router).
- whether or not eth0 connection is connected or disconnected makes no
difference to wlan losing connecting and losing connection shortly
afterward
