BCM5354

[Chris Martin]

I to am working on project using openWrt and  the  BCM5354, and we too are
using the 2.4 kernel.
However I have been testing the 2.6 with wireless compat (b43)

I was about to log an trac issues with openWrt today, but I saw this post so
I thought that would add my bit here as well.

I can confirm that It works flawlessly in client mode.  However It fails in
AP mode.

There are 2 types of errors that I encounter.  NOTE: these problems do not
appear in STA mode.  I have been using STA mode for over a month - all day.
  I am currently working on another issue, but once I have that solved I was
going to start on this.  But in the mean time I DO have the resources and
the time to test anything that anyone may suggest.  and if I find a solution
I will obviously be posting it back here.

In AP mode the time it takes for the following errors to occur varies -
sometimes it will run for 1/2 day OK.  others it fails almost immediately -
but mostly it is unusable
