I use a cable modem ( Motorola Surfboard SBV5120 ) and an ASUS router ( RT-N10E ).

If I remove the router and try to connect my comptuer directly through the modem, I get limited connectivity and it can't connect. If I plug the router back in the setup, my connection is fine ( kinda of, because my rotuer gives me some errors from time to time).

I've read that it might have something to do with MAC adresses. I have the mac adress of my ethernet card from cmd -> ipconfig /all. What do I need to do with it?


I feel that my network runs better directly from the modem and I don't need the wifi up all the time. That's why I want to connect through modem only. And my routers gives me some error about not setting the right connection type (static/automatic...) which I can't get rid of!

If it matters, two days ago a friend asked me to test with newly bought router. I replaced my own with it and got his running. Then I swapped back my own and the problems started to happen.

I'm begging for help, please! I rebooted the modem 2 times from the physical button with a needle, uninstalled network card drivers and I tried many times to unplug the modem from the wall.

And this is the error my routers gives me. I've tried to switch things in the settings but with no succes. image
 
Solution
most likely all you have to do is connect your computer directly to modem. power cycle the modem and it will associate with the PC.
