The cable modem was knocked off the desk it was on and suddenly nothing works! I own my Motorola DOCSIS 3.0 modem, it worked fine with Comcast. I had it connected to my TP-Link router (running DD-WRT). I also had a Cat 5 cable backhaul to another router that I configured as an access point.
Now, ut suddenly it all stopped working. I can connect a single computer to the modem output (WAN) with a Cat 5 cable and that works. But the TP-Link router doesn’t seem to recognize that WAN cable any more.
When I installed DD-WRT I set the IP address of the TP-Link to be 192.168.1.1.
Shouldn’t I be able to connect my MacBook to one of the 4 ports with a cable and point my browser at 192.168.1.1 and log into the TP-Link router running DD-WRT? Because even that’s not working.
