5G Hub ZTE MC801 B12 update

[5Ghub_house]

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?

This is what I am having now a year on with a new contract errgg

Been suffering this issue for a few weeks now. Worth noting that for me it's JUST the wifi network dropping off. The Wifi light on the router actually turns itself off, all wifi devices lose connection but wired devices stay up. Reboot sorts it out until it happens again, multiple times per day. 

Three support are useless and have no experience diagnosing network issues. Constantly having to correct them on their advice (I'm an IT engineer of 15 years). No apparent way of checking the logs on the MC801A anymore. Then when I caved and tried a factory reset... I then discover that since the B15 update, it now requires a special character in the WIFI passkeys, meaning I now have a entire day of smart device password changing/repairing with my smart home system. I refuse to have to do this, so I've now ordered a 2.4Ghz access point for tomorrow to run my smart home devices whilst I sort out this god dam issue. Feel helpless since three support literally do not know what they are talking about. 

Was totally fine before B15 update, so in my case this update has not fixed it, it's had the opposite effect. But not sure if my issue is different to yours, since mine is only the wifi network going down.

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 did this get released im on BD_UKH3GMC801AV1.0.0B10

Hi @adii_ii,

Usually your router should update to the latest software overnight or after a couple of reboots. So if you've just got it, this ought to update after a day or two. If not I'd recommend to contact the Broadband team to see if they can remotely update this for you.

Thanks,
Jonathan

I have that firmware on my ZTE modem and it drops out several times a day.

A restart re-connects straight away. Perhaps its a ZTE hardware issue ?

Is your problem still good since the update? I'm also on B15 since 2nd March but the issue of drop outs still persists. I'm using my router in bridge mode so not using wifi.

Not necessarily: my problems (the same issues that everyone has withy b12) only started when my router updated to b15 last week.

I have had my hub about 2 weeks. Worked fine the first week. Now requiring daily reboots. Three Support saying it is a network issue crashing the router. This feels unlikely. Software Version BD_UKH3GMC801AV1.0.0B15
