BT Additional Disc for AX3700 Whole Home Wi-Fi System | Extend Mesh Network Coverage | App Control & 3-Year Warranty | Perfect for Large Homes & Multi-Story Buildings

I was a bit nervous about buying these discs are seeing a lot of negative reviews. However, BT released a firmware update on 20/4/20 that has dealt with most of the issues & they are also promising an exciting roadmap.BT Wholehome Premium is superb value offering Triband with the latest 802.11ax superfast wifi (currently used for backhaul between discs). There are also, a number of other improvements over the standard BT Wholehome discs, including two RJ45 ethernet connections and a detachable stand that can be used for table and wall mounting.I've now installed the discs, updated the firmware and connected all my devices (Smart TVs, lots of Teckin smartplugs, Ring cameras, Sonos speakers, several Amazon Echos, Firesticks, iPads, iPhones, Android phones, laptops, games consoles etc).The basic installation was very easy. I did have an issue with the firmware update, which left the discs "blinking in update mode" for several hours, although I could still use the Wifi while this was happening. I used the BT Community for advice and they told me to power off and back on. This solved the problem. I also had a slight issue with Netflix support on my Smart TVs - there was a connection error to Netflix Server 1, but this has now resolved itself & working perfectly.It's so nice having super fast wifi access across the whole house with just one Network ID. No "not spots", no weak signal areas and seemless connection to the best disc as I move from one room to another. And having the 802.11ax standard should future proof me for the newer products that support this standard.My only real issue was that I couldn't turn off the 5GHz access (or name the 2.4GHz & 5GHz networks separately). I have a large number of Teckin smart plugs around the house. I use these to switch on sidelights using Alexa. Unfortunately, the smart plugs only work on 2.4GHz. There is a phone app to set the smart plugs up, but your phone has to be on the same 2.4GHz network. My phone kept defaulting to 5GHz, so I couldn't configure the smartplugs. I solved the issue, by switching off the Wholehome network and configuring the 2.4GHz channel on my BT Smarthub Router with the same name and password as my Wholehome network. I could then configure all the smartplugs using the 2.4GHz access point. I then disabled the 2.4GHz accesspoint (I could have just renamed it) on my BT Smarthub and turned on the Wholehome Network. Voila - all the Smartplugs are now connected to my Wholehome Network. Alternatively, I could have just changed the Wholehome Network name and passwords the same as my existing setup, but I wanted to change them into something meaningful for me.With a large network and a largish house, it was never going to be easy upgrading my wifi. But the experience with the BT Wholehome Premium has been very good and the result is brilliant.Don't let the negative reviews put you off, the latest firmware has resolved most of the issues.
