5G hub (Greenpacket Y5-210MU) dropping wired connection after a few days every few minutes

[JohnR]

First, it seems I'm not alone: https://www.ispreview.co.uk/talk/threads/drop-out-problems-with-new-three-outdoor-hub-y5-210mu.42890...

tl;dr - I've only had the Three 5G broadband package for 1 week. I didn't alter the 5G outdoor hub  configuration, which is running firmware 130.00100.113.024. After 6 days of flawless operations with minimum 300/20 Mbps downlink/uplink, the 5G outdoor hub started closing the ethernet connection intermittently every few minutes, and the only fix (so far) is a reboot of the hub. I'm willing to help the Three engineers debug this (I have networking experience), but if it can't be properly fixed (firmware update?) or if they aren't interested, then I'll have to cancel the contract as this is a deal breaker. 

Details:

The outdoor hub (Greenpacket Y5-210MU) seems to intermittently close the ethernet connection. I've debugged this several ways: with a laptop directly connected to the hub via the PoE, via the eero, via its own web GUI (192.168.0.1).

I've only had it for 1 week. Worked fine for 6 days. Then last night I noticed intermmittent dropouts. Pinging google.com continuously revealed the dropouts last 30-60 seconds, and happen every few minutes, from 5 to 10, but especially if there is any network activity from some connected client (phone, laptop, etc).

I used several methods to discover this:

1. the web gui's advanced > system > ping (which pings directly from the hub, independently of any connected router/eero/device); this always works fine, so I know the 5G connection is working 
2. a laptop connected directly to the hub; when it happens the laptop OS reports ethernet disconnected
3. the supplied eero 6 router; when it happens, the eero's led turns red, and the eero app says "Internet Offline, Wired Connection Not connected". 
4. The syslog logs don't show anything suspect, which to me suggests a memory leak of a process running on the hub (syslog logs downloaded from web GUI > advanced > system > maintenance > syslog > download) 

I waited for almost 24h, during which it lept happening continuously, then I rebooted the Greenpacket outdoor hub and voila ... came back to normal.

From experience with modems and routers, this is a symptom of a memory leak of a process that runs on the Greenpacket hub, which builds up over time until it fills the entire memory, and then all services get affected, causing interruptions everywhere.

Are there others experiencing this?

Are there any Three employees here willing to help with this?

Here is video evidence that TR069 can't be disabled (at least not by clearing the acs username as you claim): hxxps://imgur.com/a/Ni1qNT0 (replace hxxps with https)

Do you have video evidence that it stays disabled after a refresh?

EDIT: Wait! I could disable it by NOT clearing the "ACS User name" field (if that's what you meant then my bad). I'm now curious if "cwmp" will still show in the logs. I note that I now have 47+ days uptime, see below. I did have one downtime last week where my Asus router couldn't see the internet any more, but it came back up by itself, so that likely was the actual 5G connection dropping. What I do have now every couple of days are short 10-20 seconds slow-downs, as if the bandwidth suddenly drops to 1mbps then recovers.

I made other changes to my setup (the TR069 stuff wasn't disabled) which I detailed in other replies in this thread (see here and here), particularly a high quality aftermaket PoE injector with integrated switching power supply. The firmware version didn't change, so either Three has made modifications remotely to the hub in the meantime (very unlikely from what Johnathan reported in a private discussion), or one/more of my changes made a difference.

I don't think I have ever suggested clearing the ACS User Name, if I have in which post so I can correct it

The Request User Name field needs to be cleared because, in at least some cases, it is initialzed with a value that is rejected as invalid  on subsequent TR069 update requests

Didn’t work for me. I’ve had two drops, and didn’t come back at all. Reverted back to LTE only for now. 
Come on three @JonathanB this is ridiculous.

The not automatically reconnecting is very worrying and I wonder what is diffferent about your environment.    Touch wood, mine always reconnects and a short outage when you are not actually using internet is not really a problem,  more of a problem if SWMBO is watching a streaming video at the time!

I had already done both of those 3-4 days ago when you first posted the trick about clearing the user name to disable tr069, then yesterday I had another link drop. It came back by itself this time.

My guess is the same as I posted in my original post: a memory leak.

[sargentdel1]

I can’t seem to find this on mine. Any suggestions?

You must use the "admin" userid, password on hub label, to see the TR069 settings

Same issue here. Router randomly drops connection to 5g and the only resolution is to reboot the router. 

Ended up using another 5g router as the greenpacket hub isn’t reliable enough as I work from home. Hoping Three will fix now as there seems to be a lot of customers having the issue. Surely all they need to do is get one of the routers showing the problem. Happy to send mine back as it’s useless to me.

Gave up on this is the end and replaced the router -  no more issues.  Now no reason to stay with Three when my contract expires.  Happy days.

@Brianboitano 

Getting a bit confused - you have posted two different solutions, a minute apart, as having fixed your problems

Using a smart switch to reboot the router and replacing the router.

By router I assume you mean the Y5 external hub rather than the internal Eero router

Which model of router has solved your problems?  Internal or External?

There are at least two different issues for Three to solve

1. What causes the loss of connection?
2. Why, for some customers, does the hub fail to automatically reconnect until rebooted?
