I have TalkTalk Full Fibre connected to a Erro Router which is connected to the TL-SG108S Switch

Conected to this we have 2 PC's, a Talk Talk voice adaptor, a Talk D-Link extender and a Sky-Q main box whchich conects via WiFi to 3 mini boxes.

All has worked fine until a couple of days ago when we lost the connection to everything connected. I unpluged everything and after plugging them in again everything worked, apart from the Sky mini boxes, for which I had to speak to Sky who talked me through how to reactivate them.

Today we lost everything again!

When i disconnect the switch and connected each device directly to the eero they work ok.

As it is to do with the Wi-Fi side of things, I don't supose it is connected in any way but we keep have the 2.4mhz band drop out!

Any help would be appreciated!
