Good day,

I have a strange problem when connecting my tp-link range extender to my existing network. 

I have a router that broadcasts a 5G and 2.4G network, I connect the extender to the 2.4G network, and as soon as I do that I have limited connectivity on the 5G network. Although the 2.4G network and extender, both have internet access.

What I have tried so far:

Setting the range extender to automatically obtain an IP address from the main router

Switching off DHCP from the extender to ensure an IP is assigned from the main router.
