WAN port unplugged error - Archer C7
I have recently purchased Archer C7 router for my home, till date it seems to be working very well however today I got an error message "WAN port unplugged". I did check the cable and connections, everything seems to be intact. I tried trouble shooting this error however nothing worked so I did reset my router after which it started working. About 2 hours post the fix again I got the same error. I don't think reset option is feasible every time I run into this error. Please help me with steps to resolve this error as a permanent fix. Thanks in advance.
