I have a BT Whole Home Wifi system (the original large discs), with 4 discs covering my 3-storey house (in the UK). I'm happy with the wifi coverage and speeds that it provides, but I get problems from time to time with devices dropping off the wifi network and not being able to reconnect (I try power cycling the device in question, at least a couple of times). This usually requires power cycling one of the BT discs (after trying to working out which disc the device had been connected to). I usually try restarting my router first, but that doesn't usually fix the problem.
I have no idea why this problem occurs, and it's pretty annoying having to go around the house turning the disc(s) on and off. This has the other unwanted consequence of devices reconnecting to the "wrong" disc after discs are power cycled - for example, one of the discs is located close to my front door, which is perfect for my video doorbell. But when I power cycle it the video doorbell immediately tries to reconnect to the nearest alternative disc, which is much further away. I then need to power cycle the video doorbell to get it to connect to the "correct" disc, which is not straightforward).
The discs are hardware v1, software v1.02.13 build07. I have disc topology set to default, and use static IP addresses for each disc. My router is a Netgear R7800 running DD-WRT (with wifi disabled).
Does anyone have any idea why devices drop off the wifi network and refuse to reconnect until I power cycle the relevant disc? As I now have all of the discs connected back to the router via cabled ethernet links, would I be better off replacing the BT mesh system with simpler access points?
