I have a TP Link AC1750 Archer 7 v4 connected to the modem. Each day I have this problem, Internet works fine but suddenly Wired & Wireless doesn't work. Means Devices can't past the router looked by the tracert command. But the weird thing is meanwhile I can access a computer through Teamviewer from WAN. I can ping my WAN IP from other networks. Confirmed with ISP they had no connection issues from their end. They are pointing to my router. A restart on the router gets the everything back in working.
I can log in to the Router while this problem happens & I can see the router gets the WAN IP from ISP.
I have tried everything on the internet.

Nothing helps.1) Hardware NAT disabled
2) DNS manually configured on DHCP
3) Upgraded the latest firmware
