Router can't get an IP address
This suddenly stopped working a couple nights ago, but had been working fine for months. I've talked to three different agents and been through phone attendant heck half a dozen times, and haven't gotten any closer to a solution.
I have factory reset the modem. I have factory reset the router. I have tried a different router. I have replaced the cat 6 cable between the router and the modem.
If I connect a laptop to the modem directly, I can get an IP address and get online without issue. If I connect a router (and I do power cycle the modem in between) it just doesn't seem to be able to connect to the DHCP server to get an IP address. I show all zeroes, and no matter how many times I release and renew, I am no closer.
Suggestions? I'm waiting for a call back, but I don't expect it soon, what with the pandemic. This is making it nigh impossible to work or get schoolwork done.
