Something where you had heavy wifu use for week(s) without a problem? (I know that until we got focused on this, and people focused on reporting it, that maybe it was happening in releases I'd otherwise considered to be "pretty good"... so please report in on your "best" releases this year...) Worst case we can step back to that kernel for a while and proceed forward on all the other stuff. I know I crave stability at this point, and I'm unhappy that everyone here is unhappy, too... Regrettably since losing my lab I have not been in a position to easily test wifi to any huge extent. I'm slowly building that up (but for example no longer have a mac to test with) On Thu, Apr 3, 2014 at 11:20 AM, Neil Shepperd wrote: > I just flashed 3.10.34-4 to my new WNDR3800 and experienced the exact > wifi hang described by Toke H=F8iland-J=F8rgensen.

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

OK, this brings back the device driver into the equation... I WAS seeing dhcp and arp requests "getting through" from the captures, and it seemed like arp in particular was getting through... > > but the offers aren't being received at my laptop. > > Just another data point I guess. Well, I'd hoped it would be a confirming one rather than one opening up more questions. > Neil > _______________________________________________ > Cerowrt-devel mailing list > Cerowrt-devel@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/cerowrt-devel --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
