Bcm4311 shuts down on closing lid (intended?)

Bcm4311 shuts down on closing lid (intended?)

[Ronald]

Hi,

The b43 driver in the linux kernel 2.6.24-rc7 works really good :) . 
Keep it up! However, one thing is bugging me: Why does the card stop 
sending/receiving packets when I close the lid? Is this behaviour 
intended in the new driver? If yes, can I disable it?

						Kind regards, Ronald

P.S. I have a broadcom 4311 with an unpatched kernel running Fedora 8

I guess the machine goes to suspend, right?
You obviously can't use the machine when it's suspended.

I'm pretty sure there are no lid related routines in the wireless
driver, though. ;) So the problem must be somewhere else.

and it seems fixed. I only removed nl80211 from the configuration. I 
will chech later if this makes the difference....

We had this before. You're wrong, the software isn't shut down. But the
antenna in your laptop is in the screen so you're moving it from upright
to horizontal which makes your signal strength drop enough to not work
any more.

So that means the other drivers (bcm43xx and ndiswrapper) provided 
enough signal strength to keep the wireless going even when it was 
horizontal?

P.S. I want to add my wireless card to the list (of working cards) (it's 
not dell). How can I do this?

Hm, ok, that is a bit odd, I wouldn't have expected bcm43xx to do that.
Are you sure you're testing in the same place with the same distance to
the AP etc?

You can't edit the global list, only the per-driver list, for that you
need to sign up to the wiki and log in.

I'm not quite sure anymore about the bcm43xx behaviour. But I'm sure of 
ndiswrapper. Need to test bcm43xx?

Ok, well, I'd expect it to be the signal strength then. The original
driver may well be doing better than b43 for obvious reasons.

Good point, the old driver is more stable. But both ndiswrapper and 
bcm43xx fail to initiate WPA2 connections.
