Hi Peter,

While the devices are similar in nature they are different in their software so should not be affected.  Also the Chromecast I think you are referring to was an issue with Google and their Cast service.  This was misrepresented to be an issue on our Archer C7 but it was actually the Archer C1200 that was affected.  This issue has since been corrected by both us and Google.   There is only one realsed frimware for that version so that should not be the cause.  If you can share you logs so we can see the messaging we should be able to help issolate the cause or what is happening. 

Thanks. I'll grab the logs the next time the disconnect happens.  Hopefully the ethernet connection will still be available.

I can't get to the logs.  The router locks up when it disconnects.  I can't even access it through a hardwired ethernet connection.

Any other advice?
