Re: Broadcom b43 wifi fix - the easy way

If it does not solve your issue, try debugging wpasupplicant as in the thread referred to and post the content of wpa.log.

Re: Broadcom b43 wifi fix - the easy way

Hi guys - it now connects to the b/g hidden network, but not the dual band 5GHZ one.  I presume this is a restriction of this paticular driver?

It works on Xubuntu on the other partition - so I don't know :-/

I'm just about to read the thread you've linked to, so if the answer's in there I'll hopefully find it smile

Re: Broadcom b43 wifi fix - the easy way

Unfortunately, this was the only successful answer we found for the BCM4312 card over there...

Re: Broadcom b43 wifi fix - the easy way

TBH it's not a major issue - the speed isn't noticeable most of the time, and now that I can get on to the hidden network I can get to my NAS, which is the main thing!

Just curious really.

Symptoms when I try to connect to the 5GHz network is just a constant 'connecting' dialogue, and nothing else.  It doesn't ask for the key again or fail to connect, it just keeps trying indefinitely until I get bored.  This was the same behaviour for the 2.4GHz network before I followed your instructions above, and it would only connect to the visible network.

Since using the instructions above it connects faultlessly to the 2.4GHz hidden network (although it defaults to the visible one and won't let me delete it!!), but yeah, it's made a world of difference.

Re: Broadcom b43 wifi fix - the easy way

Worked for me on my Dell Mini9 (Inspiron 910) with WPA -- wouldn't work otherwise!

Thanks much!!:D

Re: Broadcom b43 wifi fix - the easy way

@weenerdog:  Glad it helped!  Just as a matter of curiosity, what kind of wifi router are you connecting to?  The default setting (QoS=1) worked fine with a Netgear router and whatever we have at work, but I had to use the above fix to get it to work with a Belkin router.  (Still works at work. smile)

Might be a WPA-specific issue then...

Re: Broadcom b43 wifi fix - the easy way

A little off topic maybe, but if we have had an "solve your Broadcom wifi problem monster thread", I guess
it would have been over 800 pages long by now.


Time to move on!#

Re: Broadcom b43 wifi fix - the easy way

You got that right... im never getting a pc witha broadcom wifi card in it ever again. Im using their wl driver but its buggy and slow to connect. pisses me off.

Re: Broadcom b43 wifi fix - the easy way

The 2-line fix by pvsage works perfectly for the Dell Mini 9; and by extension, should work for Mini 10 and other Broadcom B43xx based cards (vice modifications by means of ndiswrapper, etc.).  This is a very elegant fix.

Re: Broadcom b43 wifi fix - the easy way

@ESB:  Thanks for resurrecting this thread; I keep forgetting to edit the first post to show that it seems to specifically be a lpphy problem.  (This hack has been reported to bork wifi with other BCM43xx chips.)  Fixed now! cool

EDIT:  As noted in the first post, this fix now seems deprecated; as such, I'm closing this thread to help prevent future confusion. ops
