Disconnected from cable modem, I’m attempting to secure down the Mk3 before I open the modem to evil. If I change the router IP and apply changes, I get the message “Unable to reach web admin. Connecting in 30s” Never does. Just hangs. Can’t log on with any IP. Throughput status is just spinning icon. The only cure is a hard reset.
Tried to change the LAN port settings from auto to 1000Mbit. When I apply changes, it just hangs. Tried with cable modem attached. Hangs.
Trying to get 250Mbit speeds but the best I can get is 100. Connecting to cable modem directly gets me 225 Mbit so the router is the problem, not the ISP.
No. A “plain ol” ethernet cable. A cross-over cable is not needed. I’d use at lest a cat 5E or cat 6 cable.
I don’t think this is related to your problem.
Suggestion: From the LAN side, directly connected with an ethernet cable, change one parameter at a time to secure the router. Example, in part:
Change the password
Change the port number from the default to a high number
Disable HTTP and enable HTTPS
Disable WAN port access (if you don’t want to use a valuable tool such as “Router Utility”)
Don’t proceed to the following step or do anything else until you can make contact with the router. What you are describing is uncharacteristic of this product in our experience.
