Is there a recent version that people had that was seemingly stable for<br>
wifi that we could step back to and bisect from? Something where<br>
you had heavy wifu use for week(s) without a problem?<br>
<br>
(I know that until we got focused on this, and people focused on<br>
reporting it, that maybe it was happening in releases I'd otherwise<br>
considered to be "pretty good"... so please report in on your "best"<br>
releases this year...)<br>
<br>
Worst case we can step back to that kernel for a while and proceed forward<br>
on all the other stuff. I know I crave stability at this point, and I'm<br>
unhappy that everyone here is unhappy, too...<br>
<br>
Regrettably since losing my lab I have not been in a position to easily<br>
test wifi to any huge extent. I'm slowly building that up (but for example<br>
no longer have a mac to test with)<br>

cool you disabled guest and babel. So far we've sort of ruled out<br>
6in4 tunnelling, and syn flood protection.<br>
<br>
Sounds like you are going to stick with -4 for a bit?<br>
<br>
what I've been doing is mounting a usb stick, and just running continuously<br>
on the stick<br>
<br>
tcpdump -s 128 -i ge00 -w ge00.cap &<br>
tcpdump -s 128 -i sw00 -w sw00.cap &<br>
<br>
This definately hurts performance...<br>
<br>
And it's probably time to do a tcpdump on the connected device as well.<br>
<br>
In terms of other diags... (any suggestions?)<br>

Hmm. OK, this brings back the device driver into the equation... I<br>
WAS seeing dhcp and arp requests "getting through" from the captures,<br>
and it seemed like arp in particular was getting through...<br>

Well, I'd hoped it would be a confirming one rather than one opening<br>
up more questions.<br>
