Drop out problems with new Three outdoor hub Y5-210MU

[Kylep]

I'm really hoping someone can help me. I have recently signed up for Three 5g home broadband. Initially had an indoor router but switched the the outdoor hub green packet Y5-210MU. I'm experiencing great speeds, but what seems to be a common issue of the connection dropping out once every 24 hours or so. It requires a reset at power supply to correct this, so not ideal! Device still has 4g or 5g light on, but is not connected really until reset.

After some research, I found people suggesting the connected router should have 5g wifi disabled to allow the modem to work properly. I cannot think why on earth this would be the case, but I tried it anyway. At the same time I did a factory reset and thought I fixed the issue. I had no drop outs for 48 hours. However this morning it happened again...

I have also seen suggestions that this is a firmware issue with Three, but I would imagine there is a way to fix this in the device settings. If anyone can help I would really appreciate it. I don't want to switch back to the indoor hub as the speeds are not as good. Even if someone can shed some light on what precisely causes this so I can predict the drop outs it would be great... the drop outs SEEM to only happen at night, so i am even happy to reset the device using a timer at say 3am every night if that solves the issue as a workaround (I'm on a house boat and powering the device direct from 24V so easy enough to wire in a timer.

Any feedback from Three on long term fixes here? Not seen anything concrete as a way of a solution and concerningly, ive seen a few messages stating that the Green Packet Y5-210MU may be getting sunsetted?!

I only purchased the hub as it was the only external hub on the market... We are still encountering drop outs at least Daily...

Starlink have now offered a 50% off for 2 years discount, which is going to be pretty hard to turn down. There are other external adapters on the market (and ones with much more stable firmware). 

Can Three provide an update, as this issue has been known about for months now....

Got this hub 2 days ago.  I'm getting a complete lock out at ~4am every night, and it requires a hard reboot to get it working again.

Try disabling Scheduled reboot and TR069, See my earlier posts

Yeah, I say from someone else that the red comment when clicking submit was due to a '-' in the username.  I just deleted the username and clicked save and it didn't drop last night.

However, presumably this means I'll never be able to recieve an OTA firmware update without a factory reset (possibly ever if the username is the issue)

If you set the both the Request User Name and password to admin then the Periodic updates do work. you can also change the Interval to something less than 3600 so that the updates don't occur exactly on the hour. It appears that all hubs are set to 'phone home' simutaneously and overload the server.

But even when the updates are ocurring off the hour I am still seeing significant number of failures and retries in the logs.

I am currently turning TR069 off during peak times and allowing it to run overnight, I will automate the activation/deactivation shortly.

I also suffered a scheduled reboot on Sunday 4am even though the settings showed it as disabled, so you might want to set the period to the mamimum 30 days (advanced->maintainance) as well as setting it disabled

Hi, update for all. Just on support chat, latest is "actively investigating reports to identify a permanent fix". Ive provided as much background as possible and Thee customer services to be fair are doing all they can. With the exeception of the drop outs, I am really happy with the Three service thusfar. THey suspect that in addition to the adapter not failing gracefully, there may also be network related issues associated with this - sort of triggered by a coverage issue, but then not handled brilliantly by the adapter/firmware mix.

Its a real shame - I actually want to double up my connection as we are a heavy data user, particularly with my work. Until its fixed though, we will be sticking with a single hub.

Can Confirm borking the diagnostics feed as suggested by tech ledgend MyMsMan fixes the janky firmware issue that is causing disconnection issues.  Solid conection, no drop outs and finally, a service to rival Starlink at half the price. 

Have you tried disabling the TR069 service?

I haven't had a disconnection in three weeks.

Reset (not just reboot) hub, if that doesn't help, Try:

• log on to to hub https://192.168.0.1 using userid admin and password printed on hub label
• Navigate to Advanced->System->TR069
• Disable TR069 and Periodic Inform
• Submit, if that fails with a red message then clear 'Request user name' field and try again.  Do Not clear 'ACS user name' field
• Navigate to Advanced->System->Maintenance
• Disable Scheduled Reboot or change to a less frequent interval (days)
• Click on Scheduled Reboot

Alas, fixed for a while, but now back to resetting the hub multiple times per working day (normally in the middle of really important teams calls...)

Trouble with stopping TR069 is that you are blocking automatic updates to the firmware. 

I have looked at my version (130.00100.113.024 as of 14-Sept-2025) and wanted to know if there were any updates. I usually flash routers to latest FW. But after a bit of a poke around the net I found that only Three have the versions. 

From one of the many sites on the internet which describe the protocol:

"TR-069, also known as the CPE WAN Management Protocol (CWMP), is a technical specification developed by the Broadband Forum (BBF). It is designed to facilitate the remote management and configuration of Customer Premises Equipment (CPE) by service providers. The protocol enables automatic configuration, software and firmware updates, and diagnostics of devices such as routers, modems, telephone adapters and set-top boxes."

@gavinmcnair has a clever (ugly!) fix using something like Home Assistant to monitor the connection and if it sees it drop it restarts the router using an API. https://github.com/gavinmcnair/Y5-210MU-restarter

If you re into software its easy to set up.

BUT this does not fix the underlying issue of a router which is borking because it feels like it.
