So my router works fine until I connect my TP link range extender.
Once my tp link is connected, the devices connected to the tp link run fine. No problem.
When I try connect my laptop, xbox or tv to the main router, it connects but no internet seems to be there.
I connect the same Xbox, laptop and tv to the tp link, and they work fine, albeit slow which is why I want to connect to the main router for the best speed
Any advice would be great
