My Sky Q box will not stay connected to TP-Link Deco XE75 wifi 6 mesh

[Stephen142]

I installed a TP-link XE75 pro wifi mesh a few weeks ago to replace my old BT wifi network. Initially the sky q box seemed to connect and work ok but now it constantly drops off the wifi.

My current configuration is a sky q box linked to sateliite dish and wifi,  and a sky mini box with an ethernet cable link to the main sky q box.

Anyone with same issue or ideas to fix?
