Possible fix for b43 related stability issues

It seems someone has finally made some progress on why b43 seems to randomly stop working, and it's related to the wifi switching between 802.11b and 802.11g rates:

A temporary fix is purportedly to force the ap radio and your client radio to only use 802.11b or 802.11g rates. Depending on your interpretation of Hauke's comment, just forcing the ap to use only the b or g rate may be enough. I am currently testing my router with the following command (which I ran from a ssh session):

iw dev wlan0 set bitrates legacy-2.4 6 9 12 18 24 36 48 54

If you are using a wrt54g, wrt54gl or some similar router, it might be worth a try.

Ok I will try this on the WRT54G v3.0 and see if this works.
We've set set the DHCP Lease Time to 8,760 hours as we thought this will fix it.

iw dev wlan0 set bitrates legacy-2.4 6 9 12 18 24 36 48 54

first if this doesn't work we will try

iw dev wlan0 set bitrates legacy-2.4 1 2 5.5 11

:D

ok we tried the fix and it didn't work.
cannot connect to the internet and wifi for some reason.
we don't know how to revert the changes so we'll re-image to 1.4.6 or 1.3.6 to see if that works for us.

Anyone want to try porting these patches to Backfire and save WRT54GL routers from extinction? Eric?
