Comment 54 for bug 425455

Same here with ubuntu 10.04 Lucid Lynx

Iwifi connection (with WPA personal encryption) is established correctly (using NetworkManager), but after a 30s or so the connection is lost and it's connecting again, connected, but then lost again and again.

wifi card is Intel Pro Wireless 3945ABG

here is a part print of dmesg:
