I have a skyq router, main skyq box plus one sky mini that are all Ethernet cabled. Like a lot of people I am experiencing issues with WiFi  so have decided to go down the deco m5 route to help the situation

There are 3 of us working from home and a daughter who would be very upset without sky so I would like to make sure I get this right. If anyone could confirm the steps below are along the right lines and provide any additional advice it would be appreciated.

skyq boxes - turn off WiFi on sky main and mini boxes (probably off anyway)

                      Turn off WiFi on skyrouter

deco m5 - configure deco in router mode

My PC is also hard wired to the sky router but I presume I could conn3ct this to the Ethernet port on the m5. Is it also possible to connect a 5 port Ethernet switch to the back of the m5 so I can add other hard wired devices

thanks in advance
