WiFi Range Extender causing original network to be unavailable
Hello,
I have recently set up a TP-Link WiFi range extender in my home. Since setting it up, I have noticed that any device (laptop, desktop computer) trying to connect to the original network (i.e. not the range extender) is unable to connect. Over WiFi it says 'Connected, no internet' and for Ethernet connections it seems to show it as an 'Unidentified Network'. Connecting these devices to the extender works fine, however this is not ideal as my device is right next to the router and I would prefer an Ethernet connection.
I am sure it is the extender causing this issue as when I switch it off the Ethernet connection immediately works fine. I have factory reset the extender and the issue still persists.
Please could someone advise what I could try here? Thank you
