The internet with the Spectrum router worked fine as far as computer/streaming/etc, so I know it’s not a lack of internet through the modem. Any ideas? Thanks.
Re: R6120 install
Make sure you start things in the correct order.
Power both the modem and router off
Now power up just the modem and wait for it to stablize, could be 5 minutes or so.
When modem is totally now power up the router.
Hopefully this will fix your issue.
