So, I was messing around in the in-browser router config. and I cloned my MAC address from my laptop that I had hardwired to the router and saved changes.
After I did this I could no longer connect to the internet via ethernet cable from the router. However, I can connect wirelessly. I went on the "original" computer, my desktop, and cloned its MAC address for some reason thinking it may fix the issue, but no dice. I unplugged the router and modem for about 15 minutes, then turned them back on. I still could not connect while hardwired to the router.
Before all this I saved the router's configuration using its own save/restore function. Restoring it to previous settings did not help, for some reason.
I would like to know if there is something I can do to fix this before I have to annoy my ISP.
Thanks for your question DevPolarbear.
Is your Modem Wireless and is your router wireless. If both are, that may be part of the problem.
What is the make and model of both Modem and Router.
You didn't spell out your hardware or type of ISP but based on the problem, I suspect you you have Cable Internet.
If this is Cable Internet, the order you start your Modem and Router in matters after making a MAC address change.
You need to power off the Modem and the Router. Make sure all of the lights on the Modem go out. If they don't, it has a battery backup in which case the battery needs to be removed. After both units are for sure powered off by unplugging them, Start ONLY the Modem and allow it about 30-60 seconds to boot. Then start the Router. The Internet should then be working normally.
