What's wrong with my home network? (lemmy.ml)

This all began when the power went out this morning. I have several wireless routers, a network switch, and a starlink modem/router. Internet comes into the starlink box which has it's own network called 'MyLink'. From the box, it gets split to a network switch, which connects to all of the ethernet jacks and a second wireless router called 'MyLan'. The starlink has a second output that connects to a third wireless router called 'MyLink2'

The problem is I can connect to LAN and ping other computers, but they only operational internet over wifi is from 'MyLan'. It will work wherever I connect it over ethernet. NONE of the other routers has internet for phones or laptops. With the mindfuck of an exception of a smart TV which can get internet over MyLink2! None of the ethernet works for anything other than wherever MyLan is connected. I've tested it several places.

The connected to internet light is on for all routers and I've done a factory reset for all routers except the one that is working. Anyone have any ideas? I'm losing my god damn mind over this one. I remember a few years ago I had to contact my isp to reset my connection from their end. Could that solve the problem?

it sounds like the gateway(s) are misconfigured

If you have network issues generally best practice is to unplug everything for 30 seconds and then turn the devoces on one by one from where the internet comes into the house and let each connect before moving up the chain. So typically modem then router then computer.

Reset the last one. It probably has a bad table configuration or has reverted to a default of some sort.

I've had an overvoltage (I think) burn ports on my switch. Short loss of power during a storm.

It was an adventure to find that problem, and it felt like magic too. My only advice is to diagnose if starlink port 2 is burned (just connect the working network to it and see if it still works) and if not, get a replacement for your 2nd router.
