5G Hub ZTE MC801 B12 update

5Ghub_house — Sun, 06 Nov 2022 17:32:43 GMT

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?

Hi @5Ghub_house,

Welcome to the Three Community. I'm sorry to hear that you've been experiencing these drop outs the last few weeks, this sounds really frustrating.

It sounds a lot like this thread here:

Are you able to confirm that the issues are only affecting the router, for example do you have a Three phone and SIM also that's not affected by the issue? That might help clarify if the network issues are relevant.

I'm making enquiries about the firmware question based on what I've seen on the other topic I've linked. I'll let you know if I find out anything on that side of things.

Hi @5Ghub_house,

Quick update on this, there's no known issue with that firmware update, but we're keen to investigate further in case we're missing one. I'll private message you for a bit more info to support the investigation.

@5Ghub_house I have the same router, how do you find out what update version its on? It was around middle of October that all my problems with sky glass started so I'm wondering if my router has had the update too🤔

bethanrex — Mon, 28 Nov 2022 13:46:45 GMT

Yes I have the same issue. Happening since about October.

I've recently been working with support on this and they called me today to say it should be fixed but its dropped out again today so it's unfortunately not.

I have the exact same issue. I have to restart the router every hour to get the good speeds and then it drops out. Very disappointed

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 "

We’re fixing an issue with our network in this area

We’re sorry for any disruption you experience. Our engineers are working on masts nearby, which means the rest of our network is handling more traffic than usual.

Updates on our work will be posted here. We’re working as fast as we can to build a better, stronger network in your area."

This message hasn't changed!

Happened around 17th October onwards and I have to manually reboot my router, or switch it off and on again. Happens pretty much every day, varying times of the day. Annoying.

5Ghub_house — Tue, 03 Jan 2023 15:09:36 GMT

Interesting. I haven't called because when we last called they couldn't understand us. So I haven't bothered to phone. Just keep rebooting

Re: 5G Hub ZTE MC801 B12 update

5Ghub_house — Tue, 03 Jan 2023 15:10:28 GMT

Feel your pain. For us its pretty much every day. I have been noting the times. When I reboot we are back on 5G with speeds around 320Mb.

gazzaman2k — Mon, 06 Feb 2023 21:14:02 GMT

mine to does the same thing, a quick powercylce and it comes right back, or if you give it 15-20minutes it just works again, its a pain, it was fine on b09 firmware now b12 has ruined the modem by making it disconnect every few hours or so, i even had the modem set to non auto update but three forced the firmware on and have now made the product not fit for purpose

To find out version, go to http://192.168.0.1/index.html the password should be written on the sticker to the router. When you are logged in, under status information click 'detailed information'. The software version is listed there. mine ends with B12.

I saw something outside this community on another blog website where someone said they changed the PDP type on the 3Internet APN from using ipv4/6 to just using ipv4. I did this on 13th Feb 2023 and since then I haven't had to reboot the router. I haven't had the internet just cut out on me on daily basis. I know its only been four days since I changed that but it seems to have improved the situation. I am now wondering if the B12 update they pushed out on 17th Oct 2022 altered the PDP type to ipv4/6. And the v6 part causes upset. Anyway, for those having this internet issue, if you want to try it out, go to http://192.168.0.1/index.html Then on the first page, you may have to temporarily turn 5g toggle to off. Go into 5G settings. Choose APN. Mode to manual. Create new profile name, i called mine 3Internet. PDPtype= ipv4. APN = 3Internet Authentication - NONE. don't enter anything into username/password as these are not used. If you had to switch the 5G toggle off, go back to home screen http://192.168.0.1/index.html#home and turn 5G toggle back on. That's it. If this works for you also, then i guess it could be the resolving factor of the daily internet dropping issue.

Thanks so much for sharing this @5Ghub_house. Hopefully some other community members can share if this works for them too.

We currently only use IPv4 for these routers, so it does seem like a promising solution.

Thanks,
JonathanB

I spoke too soon when I wrote. I had updated the APN setting to ipv4 only on 13th Feb 14:38. However after that on 17th Feb 13:11 the internet dropped again and I had to reboot the hub. Then again on 19th Feb at 18:49 the internet dropped again and I had to reboot the hub. Then again on 20th Feb at 13:03. I guess I will just have to keep rebooting the router every single day manually.

Quick update, after updating the router to IPV4 only we haven't had to reboot the router since 20th Feb 2023. We also telephoned Three customer services and went through some checks with them. Then surprisingly when I logged onto the router (192.168.0.1) today it said the router had updated successfully, Upon checking the router it had updated on 2nd March 2023 at 02:45 GMT to version BD_UKH3GMC801AV1.0.0B15. So now we are using B15. We will have to see how this version goes. Too early to say. Has anyone else's router updated?

I'm having the same problem with super speed (300) after switching 5g off, changing status to 5g only or auto (or back again) on the modem control panel then switching 5g on again. Only to find speed dropping to sub-4g levels (45) an hour or so later. Then doing the 5g on/off brings super speed back. Very tedious.

Re: 5G Hub ZTE MC801 B12 update

anotherstuart — Tue, 07 Mar 2023 15:20:59 GMT

Now nothing is bringing super speed back and it's down to 0.5 sometimes. This is hopeless. Can we get the new modem? The app that is supposed to help you place or well doesn't even connect to this one!

I have the same hub Three ZTE MC801 5G since Dec2022 and from day one getting the same problem. Cutoff at least 3-4times a day for 4-5mints. Even Three replaced Hub with another ZTE Hub still problem remains. Hoping to resolve with new upgrade. Thanks for sharing.

Thanks
