Current set up:

NAS connected directly to Sky router downstairs

Work laptop and desktop PC upstairs. I use the Desktop to manage files on my NAS

I have installed the TL-WPA8631P kit with my router plugged into the adaptor and the laptop and desktop plugged into the same extender upstairs via ethernet cable. Both devices have WiFi turned off.

When I check the laptop it says it is connected to SKYZTGD.

When I check the Desktop it says it is connected to TP-Link C156.

The problem is I can no longer access my NAS via my desktop. I assume this is because the Desktop is connected to TP-Link C156 and the NAS is connected directly to the router. When I try to launch the ASUS control centre on my desktop it says no NAS was found on the local network.

Does anyone have any suggestions as to how I remedy this?

I have tried restarting devices, resetting devices etc etc. but it doesn't seem to change anything.
