Tp-link Archer AX55 No Internet Connection Issue

 For some reason Tp-link Archer AX55 Wifi Router refuses to connect to the internet. All the cables are fine, the Modem is working fine, computers connected to the switch and then to the Modem are able to connect to the internet via Ethernet, no problem!

 Tp-link Archer AX55 is not happy and the internet led stays orange. In the Tp-link settings it says no internet connection. Not only, but I kept getting disconnections and now way to try any other config.

Simple solution in this forum:

As it happens, I have a cable Modem, and for convenience I had connected the Modem to the unmanaged switch, then from the switch to the Tp-link router. The switch also received my three other computers. So the Modem was seeing many different MAC addresses not just the Tp-link one.

As @paulrob mentionned in his post:

Not sure if applicable, but in the UK (I am on Virgin Media) and the ISP modem needs to also be rebooted after the router is replaced.

The ISP fibre modem looks at the Mac address of the device connected to it when first booted, if the router is changed (and the modem not rebooted) then it will refuse to authorise the device.

 

Try turning off your ISP modem and the AX55.

Turn on the Modem, wait for it to boot properly, then turn on the AX55.


 Ah! Exactly, so I guess on reboot the Modem locked onto one of the other computers instead of the Tp-link, and after that, no way to make it work.


 So I unplugged everything and only connected the Modem to the Tp-link WAN, rebooted the Modem. Rebooted the Tp-link, and... IT WORKED!


 I have reconnected everything, now going from the Tp-link to the switch via the 1st LAN, and then connected every other device to the switch. This way next time there is a power outage, the entire network should reconfigure itself automatically. 👍
