I am experiencing issues with a new Deco setup at home. 

I have 3 Deco M5s which have drastically improved the connectivity in my home. 

The only issue that I cannot seem to fix (using existing TP-Link support threads) is that the latency coming off of the Decos when communicating to the main router is not consistent and frequently (every 10s or so) will drop connection entirely for a brief moment. It will be fine at 20-25ms and then I can watch the pings and see it steadily climb to 5000ms before going offline and then starting back at 20ms.

It's not noticeable usually when doing general things like surfing or watching a buffered video, but voice calls and video games are nearly un-usable.

Things I have attempted which either don't fix the issue, or stop the Deco from working at all:

- disable DHCP on the ISP's provided modem/router

- switch the deco between router and AP mode. 

- reset the deco network and start from scratch

I am not able to bridge the modem/router from the ISP because it disables other services which are controlled by the device (IE: Moca, Tivo)

I have also been testing pings directly wired to and on the wireless provided by the ISP device and everything is fine there.

I attempted to troubleshoot with the ISP but they aren't willing provide assistance when using a third party device. 

I can provide any futher information required.

Thank you,

Dave
