Router internet led is orange while connected to modem's working LAN port
Hello,
For some reason, my TP-Link suddenly gave an orange light for 'internet' and the WiFi on my phone gave an error that it doesn't have a valid IP.
My modem's LAN ports and my Ethernet cables have been checked, they all work well on other devices.
I called the ISP to undo the bridge mode to check if the WIFI from my main modem/router works, and that works well.
I have reset both my modem and my TP-Link router back to factory settings, but the problem still occurs.
The router I have purchased is not even 1 year old, it's an AC5400, hardware V2.1. It never got any 'damage' whatsoever.
I'm quite sure it must have something to do with the IP address, as I cannot even log in to my router if it's connected to my PC.
A person in our household added a new laptop to our network and then the problem started to occur.
Does anyone have more suggestions? Your help is MUCH appreciated, thanks in advance!
