Three occasional high ping + no bandwidth but still connected?

Hi all ,

I've got a Huawei B818 running a Three sim modded with external absolutely creme de la creme Iskra P60 antennas with superb stats considering the distance.

It's running V11 version of the firmware which is the ultra rare version as I understand and band locked to 3+1+32, in bridge mode and works an absolute dream with my Zyxel 2860 router as the main router in the house.

Until, occasionally I'll suddenly and unexplainedly get bouts of extremely high pings above 2-3 seconds and a few Kbps bandwidth down from the usual 100+ Mbps basically bringing the entire connection to a halt. The only thing that seems to fix it is either a reboot of the router OR manually selecting bands forcing the device to reconnect.

I'm using the 3internet apn to avoid the CGNAT as I've self hosted servers etc and generally pleased with it.

At first, I thought it was the fact I was using V11 firmware, not much I can do about that now. Then thought it was the bands, so tried different primary bands and still the same.
Tried running in DHCP mode rather than bridged and still it'll drop off in this fashion.
Tried setting manual DNS (8.8.8.8) in the APN settings and no change.

Now, the weird thing is, my parents have got a Huawei AI Cube on Three also, it's a great little device, they live 200m from a mast with astronomical stats (as expected) 40 miles from me on a completely different tower and yet they have exactly the same issue occur with their connections, high pings and no throughput and on the 3internet apn.

I'm wondering, one device is a coincidence, 2 different devices in 2 different towns on 2 different masts but the same provider is not.

So why would three be cocking about with connections like this? I mean it literally happened just now, to myself AND my parents device at more or less the same time, does that mean it's just happened to everyone else?!

They are moving onto their new "Cloud based network core". I'll check 3internet on my phone now and see if it's ****ed.

edit: yep, just checked and I'm getting pisspoor speeds to what I normally get.

In not sure if that's related at all? And likewise, why would a restart of the device fix it? Not to mention it occurs a few times per week.

I have exactly the same problem and have seen multiple people reporting this on this forum.

Works fine for a while and then randomly goes high ping and basically zero throughput. And then a restart of the router always fixes the problem. Had the same issue on 5g with the CPE Pro and 4g on the ZTE router three give out. Oddly have never had the same issue on my phone which is also on Three.
 
My cpe Pro 2 was doing that about every four days it would just really load web pages really slow... I did a speed test and 1401 Ping and about 1.0 Mbps download 0 upload. A quick soft reboot and its back to speed. I don't know.............
 
I'm having similar issues.
I've been with 3 broadband for about 4 years now and have had no issues until the last few days.
A reboot of the router sorts it out as well

I've actually recently terminated my Three contract because of this issue.

The problem doesn't seem to be end user equipment related or cell site specific. I experienced the problem:

- using two different 5G CPE routers
- using a directional antenna to connect to 2 x different Three 5G masts

In all cases the uploads and download speeds were great - typically between 500-700 down and 40-90 up.

Even with a stable connection I experienced intermittent problems as others have described - 5 to 10 minute periods where there was no throughput of data, and ping times that would go from 15-20ms to 2000-3000ms. At no point did pings fail - they would just be slow.

The timings of these outages was also pretty random - early on Sunday morning, in the early afternoon on weekdays etc. So not times where the Three network was likely to be heavily congested.

I moved to EE from Three. So far the 5G service has been very reliable. It's about half the speed of Three but still a lot better than normal VDSL broadband and comes in around £28 a month.

The three issue seems to be pretty longstanding and national - so it would seem to point to a problem within their core network / data centres.
 
This happens to me all the time - I'm getting kind of used to it now. Soft reboot sorts it out 90% of the time. I think it's because I'm on the edge of reception (and not officially within Three's indoor broadband 5G coverage range). But it is odd that it happens entirely randomly; if the signal was dropping because of poor weather or whatever then that isn't changed by rebooting my router...
 
This seems very systemic to Three.
I don't mind, but my poor parents are getting fed up with it and it's simply unacceptable to try and live with it.

Are there any Three reps here?
 
Is this why I sometimes suddenly have no data even though I still have signal? I’m using a Scancom Three SIM in an iPhone 13.
