5G Hub ZTE MC801 B12 update

I have the Three branded ZTE MC801 5G hub router. We have been with Three since July 2022. When we setup the router it was on the B09 update and we had no issues with it and got around 450Mb download speeds. Our 5G signal is around -95dBm. Then on 17th Oct 2022 our router automatically installed the B12 update. After that the router stops working at least once per day, sometimes more than once per day. When it stops working all mobile devices, laptops and the chromecast will display exclamation marks on the WiFi signal logo. If you try to navigate to any website the page will fail to load. If I log onto the router at 192.168.0.1 it all looks OK and small levels of kb are being downloaded/uploaded. The only way to fix is to either go to advanced settings > other > restart. Or walk to the router and unplug from mains power. Upon restarting the router everything is fine again and speedtest shows our usual 450Mb again. I have got so fed up that I have tried doing the factory reset on the router. This seemed to work and we went 4 days without any issue. But it happened again today. I strongly believe it was the B12 update as we didn't have the issue when it was on B09. Wish I didn't leave the default setting for automatic updates now. I have checked three.co.uk coverage page and network and looked up network maintenance and it does say they are fixing an issue in the area. However that has stayed like that for over a week. Just curious if anyone else is having an issue with the B12 update or whether it could be maintenance that is taking weeks to fix? Any thoughts?

Since our router got the update BD_UKH3GMC801AV1.0.0B15 i have had no issues. It updated on 2nd March 2023 to B15. I believe this is the solution. If your router hasn't updated to BD_UKH3GMC801AV1.0.0B15 then I suggest calling Three customer care

when will the ongoing problem with the B15 ZTE modem dropping internet ( with a good 5G signal ( as reported by modems dashboard and excellent positioning).

I get several drops a day ( very annoying whilst streaming and with longer downloads )

A restart re-established the internet connection (immediately after the re-boot)

The "service" is NOT fit for purpose

Hi JonathanB, we have two Samsung A32 5G mobiles on Smarty (using Three network) in the same house and we have no issue with 5G coverage in the house. Just to add I have to reboot the router pretty much every single day manually when I get an exclamation mark next to WIFI. I do log when i do this to see if there was any commonality to it. I also factory restored the device and it still happens.

Another point to add. when I go to Three network coverage page and input postcode the message has been the same Since October "
