@Alice_ My ISP require me to register the MAC address of the router before it can connect to their network. Your's might aslo require that. If you login on your router, you should see a WAN MAC...

@Awddrake94 Have you looked at the bottom of the router? Usually there's a password printed.

Each band is hard capped at 64 last time I checked. I wouldn't mess with custom firmware if owning a tp-link router. You'll most likely end up bricking it.

@Miloplex Never heard anything like that before. Super strange indeed.

@Miloplex That's strange, I have no issues. These are my settings (I have no wifi 6 devices :)

Works great :)
