Hi all,I'm posting hopping that someone can shed a light on to my problem

I'm running Ubuntu 10.04 LTS (Linux xarepoint 2.6.32-28-generic #55-Ubuntu SMP Mon Jan 10 212101 UTC 2011 i686 GNU/Linux
) on a intel d510MO motherboard (atom dual core)
Wireless is managed by WPA_Supplicant, with network.manager not installed.
Using standard ubunt's integrated driver



My wireless works well until i reboot, when randomly my wireless stops working.

Repeatly reboots seem to increase the chances of failure

By then wireless adapter stops connecting to the defined ESSID.

Networking restart, ifdown/up wlan0, rmmod nothing seems to make it connect.

Apparently switching between WPA and WEP solves this. Also Unpluging the computer solves the problem. Reboots (keeping the PC plugged to the outlet) never allow the connection with the AP ( Dont' know if relevant but its hidden essid)

Unplugging is not an option as these are unnateended PCs, with only remote managemnt.

It's my belief that the problem may lie on the driver, letting the HW registers from the NIC comming "DIRTY".

Unpluging assures that a proper reset (by lack of energy / power) , cleans up any registers on the NIC, allowing a "fresh" restart.


Does this makes any sense to anyone?

Can this "fresh" restart be done without disconnectingf from the mains?

Thanks in advance for any given heslp.

best regards
