Hi all, I'm having the following issue with a Broadcom 4306 802.11b/g mini-PCI card running under Ubuntu Feisty (7.04) kernel 2.6.20 and 2.6.22 with the bcm43xx driver on an IBM Thinkpad T40.
Whenever I close my laptop's lid, the wifi interface seems to stop working as I can tell by trying to ping the machine remotely: It works right before I close the lid, stops when it's shut, and *mostly* works again if I re-open. Same thing with any other network service, e.g. ssh. The *mostly*-part is what is giving me headaches. Although iwconfig shows that the association to my AP is never dropped and the interface is still configured in terms of IP address, netmask and such, every now and then I cannot connect to either LAN or WAN machines, and all I can do in such a case is re-load the driver and restart the interface. Apart from that, I'd prefer my laptop to stay connected even when the lid is closed. I have two reasons why I suspect the Broadcom driver to be responsible: First, I have tried my best to make sure no other mechanism may be blamed for the observed behavior, including disabling ACPI/APM/APIC on bootup; disabling acpid; making sure no hiberating/suspending takes place; and checking the BIOS power management settings. Second, I used to use ndiswrapper for this machine but choose to switch to the bcm43xx driver since the first would not reliably connect my box during start-up. If it did connect, however, the link would never fail during lid closure (while not changing anything else, i.e. same network configuration tools were used during, before, and after the switch). Therefore, I'd be glad if anyone has a hint what else I could try to fix this problem. Especially, I'm curious if any of the bcm43xx module parameters deal with some power management/suspend control part I could tweak. (I wasn't able to figure what every `modinfo'-listed argument means.) Thanks for any help. If I forgot some vital piece of information, please don't hesitate to ask.
