Review: Don't let the negative reviews put you off. Latest firmware fixes the issues. - 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 desertcart 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.
Review: Long term review: unreliable, unstable, useless - Long term review: I’ve been using these for four years. I’ve stuck with them only because of the amount of money that I spent on them initially. TL;DR: the other negative reviews on these are wholly and totally correct. They drop out, on average, every 3-5 days and need a full reset. Coverage and signal strength with four discs in a standard sized house is poor, at best. The app is as reliable as the hardware - rubbish. Do not buy these. Buy anything else. Full review: The principle behind these discs, as with all mesh networks, is to extend your WiFi coverage, which is usually pretty poor on the standard routers provided by BT or another network. These discs do that pretty poorly for the time they’re actually working correctly. Set up is fairly simple using the app interface, but I found that the ‘sweet spot’ for distance was really hard to achieve as the hardware seems to rely on pretty outdated technology. I have a standard four bed house and we needed four, yes four, discs to get ‘complete coverage’. They still sit on ‘amber’ for 60% of the time, showing that they’re too far apart though. I appreciate our walls are brick, which will have an impact, but still. Once set up, the discs give us about 60-70% of our WiFi bandwidth, which is pretty rubbish. The main issue, however, is this: for absolutely no reason, around every 3-5 days they just stop working. No rhyme or reason. Things appear to be ‘connected’ to them, the lights are blue and on, but our smart home tech (including doorbell) and most other things lose connection. Not everything but almost everything. You then have to go into the app and reset the network in entirety. This isn’t as easy as you would imagine. When the network is ‘down’ you regularly find that the app says it can’t find the network, so you have to find a disc that will allow you to connect by wondering around the house. And even then when you press to reset it take upwards of 5 or even 10 goes to get it to acknowledge the reset. Until it finally takes, you just get an error message saying that it ‘failed to reset’. About once every six months you also have to go beyond an app reset and perform a full factory reset, which doesn’t improve the performance issues or weekly drop outs and causes a massive headache with connected devices. Before you ask, the official ‘support’ is unfortunately either one way communication with error reporting, or an email address that doesn’t get back to you. One of the other reviews suggested that there was ‘an exciting pipeline of developments’ on the way from BT for this system. Classic BT - promise the world and deliver absolutely zero. The last firmware update was literally years ago and no performance improvements have ever been made. These are now, I’d suggest, unsupported, dated pieces of expensive, unreliable hardware. BT, as with everything you do, you should do it better and put your customers higher up your list of priorities than your profits. People of desertcart, buy literally anything else. These things are marginally decent looking garbage.

### ⭐⭐⭐⭐⭐ Super fast Wi-Fi across the whole home - works with virgin media hub 3
*by J***E on 31 January 2021*

I was apprehensive about purchasing this product due to the mix of reviews, particularly regarding using this with a virgin media hub 3. I found this product relatively easy to set up, just plug in and connect the first disk to your router, install the app and it takes you through adding and setting up all the disks step by step. The app also helps you with disk placement, scanning the Wi-Fi strength from each disk location you choose, suggesting if you are too far/too close to another disk. I was previously offered a power line adapter from virgin to improve the signal strength in the attic (the virgin router’s Wi-Fi would not reach the attic at all). Power line kept cutting out at various points in the day which was a nightmare. BT’s whole home Wi-Fi mesh system fixed all of my problems. It is so much faster than powerline (I was getting around 280 mbps in the attic, which was amazing, the same speed as being next to my router three floors downstairs). Zero dropouts throughout the day, made working from home enjoyable again as I use video conferencing so dropouts are very frustrating. The mesh network is seamless as well, can even FaceTime and walk all over the house and my devices handoff from one node to the other with no disconnection. Far superior to Wi-Fi range extenders. Overal extremely impressed, I have even bought 2 additional disks to expand coverage even further. One small issue happened after two weeks of setting up the system (therefore one star deducted for this) I woke up to find all disks were red and not working. I called BT, they were very helpful and told me that as I was using a virgin hub 3, it needed the latest firmware update. This was easily done by turning on and off the router to trigger the update on the router. Everything has worked perfectly since this. Highly recommend, especially when working from home and/or gaming and a fast reliable Wi-Fi speed is needed across the whole house.
