REopening in 2024 same issue from 2023 from a mate in this link:

Greetings fellow forum mates.

 

I've recently bought TP-Link RE450 to boost network coverage on a second floor of my house. My plan was to use it in AP mode connected via LAN to the main router to ensure high speeds.

 

The router is TP-Link Archer C2300 v1.0 with firmware 

2.0.4 Build 20210705 Rel. 72893

 

My home network looks like this. Upstairs is router which takes internet from ISP socket. It is also wired to my main workstation and NAS. RE-450 is downstairs and can be connected to the router via the cable. As normally goes, there are also bunch of other wireless devices - laptops, tablets, phones, etc.

 

 

The problem

 

When RE-450 is set up as Access Point, it causes occasional drop of internet connection for other devices in the network both wireless and wired.

The devices can still access local area network, but not internet. 

Problem can be resolved by resetting the router.

 

This happens quite randomly, but always when a device connects to or leaves network e.g. as a result of a phone switching from router's Wifi to Range Extender's Wifi. It can even happen when the workstation starts up or shuts down.

 

 

This issues does not happen when the RE works in range extender mode. Only in AP mode.

 

 

Network Settings

C2300 has DHCP server enabled as shown below. It has a number of IP reservations [192.168.0.2 - 192.168.0.10] based on MAC address for NAS and it's virtual servers and other clients get IPs from range below.

 

RE-450 receives it's IP from the router and has DHCP explicitly disabled as follows:
