Sudden sporadic drop of wifi connectivity on WRT1900ACS V2

Gurus,

I've seen this happening many times over the last month ... everything working ok, until suddenly every wifi device losts connectivity. No device could reconnect afterwards ...

This is the extract from the syslog of when this happened:

I'm running @davidc502 build of LEDE; with the latest lede packages from lede's repositories on top of it (but this happened before with just David's build )

I've SSH'd into the router from the WAN, did a "wifi" to try to re-establish the wifi , but did nothing... still not working. Had to reboot :frowning: .

yeah this is happenig to me as well with my Rango 3200ACM

I've read in other forums that it may be a utp cabling issue... do you have any cabled deviced?

i do have plenty of Ethernet connected devices

Sorry ... my bad, this issue is NOT related to cabling issues at all . I still don't know what this may be related too...

in my opinion it related to the beta wifi driver but that it just me.

Anyone have experienced this and was able to solve it?

I am have been running Brainslayers latest image for ddwrt. It is test images he is posting in the wrt3200 ddwrt/forum thread. I am not seeing this.

Ok Guys... seems that's there's no way to solve this ... I would like to ask for advice on a "workaround".... can anybody shoot me a sample script to reboot the router if it gets several ping errors from a specific address? I will have to ping a device that's always up in my home network, and if that fails, then a reboot should ocurr.

I can't thing of a better way of "testing" for a watchdog trigger, since from the router perspective, everything is ok...
