Archer C7 connected no internet
I've had the router for three months, it worked fine until two weeks ago. On my Google pixel it connects but displays "connected, no internet" and on my laptop I get "server not responding" errors. I've reset the router multiple times, changed DNS settings to 8.8.8.8 and 8.8.4.4 and another opendns combo Google suggested and nothing has worked. I set it as Dynamic IP everytime and I've tried cloning MAC address but that hasn't shown any results either. My internet works with the laptop plugged directly into the wall through Ethernet so it must be the router.
Any suggestions and troubleshooting tips would be greatly appreciated, thanks!
