RT-AC66R and PCE-AC66 looses connection to the internet and cannot contact the gateway. All other devices wired and wireless have no issues. I have 270 on the router and 18.104.22.168 on the pce...Router is in access point mode. Tried auto settings and set a channel. Set power to 90 on both. No luck. Every day or so I get this issue. I het apply or make a change on the router and it works again. Annoying.
