In my sig mate... But here is my setup in more granular detail. (With Pics further below)
- VirginMedia M350 Fibre Broadband (Router in 'Modem Mode' - Wifi Disabled)
- The 350 MBps is distributed around the house (3 floor-5bed), with no hotspots whatsoever, by Ubiquiti UniFi NanoHD Access Points (AP's) x3 at each end of the house (North / South) on the middle floor and one on the garage wall in the garden.
- UniFi NanoHD Access Points are PoE connected (Power over Ethernet) Connected via an 8 Port-Switch which has a Secure Gateway sitting between it and the VirginHub Router.
- 3 x Wifi SSID's. Private (DualBand), Guest (DualBand) & Office (5Ghz) - One AP is located in the office in clear sight of my AV equipment (A90J, Gen2 FireTV Cube etc...)
- Private & Office SSID's utilize the same Network vLan/Subnet. Guest SSID is on a segregated vLan/Subnet and has its bandwidth maxed to 10Mbps. No bandwidth restrictions on either Private or Office SSID's, they can use the max 350Mbps.
- All SSID's with the exception of 'Office' utilize both AP's via a Mesh. The Office SSID just broadcasts from the AP located in my Office.
- A90J & FireTVCube are connected to only the Office-5Ghz SSID
- A90J & FireTVCube produce wireless speeds of 280+Mbps
And here is my prefered 'Stable' setup for SkyQ (Non-SKY isp customer)
SKYQ Main - Hardwired (If nowhere near the isp Router then utilize HomePlug Adapters)
SKYQ Mini - Wireless to the SKYQ Main (Using the Main's 5GHz broadcast between the two)
[My QMain is directly above the QMini, within prob less than 2 meters between each other with only a ceiling/floorboards/carpet in between]
Now, If your QMini is struggling to retain a good wireless connection to the QMain then I would hardwire that also, into the back of the isp Router or via a HomePlug Adaptor, cause then both will be on the same network subnet and be able to talk to each other over a connection which is much more stable and consistent.
Below is what the hardware aspect of my setup looks like ( From left to right - Phone, UniFi Secure Gateway (SG), Unifi 8 Port-Switch (With SkyQ Mini sat on top), VirginMedia Hub. The 3 black Ethernet cables coming from the Switch service the 3 x Access Points described earlier. (Cat 6 cabling routed externally outside the house and to the garden) - Below the shelf (to the right) is a 1Gbps HomePlug Adaptor which services the SkyQ box directly upstairs. All this equipment sits in the lounge behind the TV out of sight.

This is what one of the internal Access Points looks like on the wall. (This one in my office)

So in summary, you can't beat Enterprise grade WiFi Access Points for wireless distribution around your home and always, if you can, ensure they're PoE via a switch instead of the daisy chaining the broadcast signals from each other like wireless extenders do. Nowhere near as good or powerful.
Hope this helps...
