Engineer Still Unable To Fix Despite New Hardware..

Patience is now required to get an engineer to fix the issue. If the engineer changed the ONT & router the next logical step would be changing the port perhaps on your telephone pole. Multiple engineer visits are the only way to resolve this. Persevere and I hope the external work fixes it on Tuesday. Fingers crossed and you’ll have a stable connection. Keep us posted.

Thanks. It's always the upload/ping recently - download is showing as a few hundred Mbps but upload has been down to 0.5Mbps and is the thing that dies. When I reboot everything sometimes it comes back quickly, but it's the upload that goes wrong. Could that be something in the router? Seems bizarre I'm having so many issues. Customer service constantly just telling me to reboot and then it works and them going great! Fixed it! Is really winding me up to be honest. They don't seem to understand what I'm actually saying and refuse to help unless I do their steps which temporarily fixes it...
 
It took nearly 6 months and multiple OR engineer visits to resolve my legacy copper intermittent FTTC issues before CF was available in my area. So I understand the frustration you are going through. Each OR engineer would change one thing and hope it fixes the issue.

Are you rebooting the Linksys router or Adtran ONT? Fibre issues won’t be fixed by a reboot and requires some human intervention. In comparison I’ve never needed to reboot my ONT or router, unless I was upgrading the firmware on my own router.
 
I think you said you had a public IPv4 right? Over all this time has this IP changed? Maybe you are being DDooS by someone as it seems equipment at your end is not the issue.

It changed since the guy came yesterday at least. Is there a setting I can change on their linksys router to protect against that? It's showing an IPv6 address too, can't remember ever finding a way to disable that using their router either

Dynamic Public IP would’ve changed if they swapped the ONT & Linksys router. However it could also be a rogue device on your LAN or WiFi potentially. So I would disconnect everything for a few hours and just test with a single device to see if it improves the situation.

Yes, it could be something internal specially since you say it’s good one minute and the other minute it starts to degrade.
 
Interesting, wouldn't that show on the router log though? Some of these Mbps look quite high but unsure if that's actually active transfer?

I've turned on the router logging to see if anything stands out, but nothing so far. Could it be the optical cable?

It seems weird the download is perfectly fine but the upload is so pathetic. Surely I'm not using 800Mbps of upload bandwidth constantly?
 
For quickest resolution before the next engineer arrives you need to prove the issues still occur when a single device is connected over wired ethernet directly to the Linksys router. Then theres no further conversation needed on wifi performance/channels or local environment.

Thanks, when it next goes I'll disconnect everything else and see how it manages...

Those values are the connected speed of each device, not active download/upload speeds.

Keep in mind most devices have active power saving, which means the Rx rates will appear low unless the device is being used.

The issue has come back after a few hours of my most recent reboot. I was monitoring this while doing a speed test (wired), download gauge shot through the roof when it was testing download speed but nothing else is taking up any of the upload bandwidth at all, so I don't think it's that. I tried a new ethernet cable between the modem and the router, and nothing again. Could it be the optical cable between the modem and the wall or the wall socket and the telephone pole outside?
First is nothing happening
Second is testing download
When testing upload it went to about 3-4 and that's it...

Random thought: Have you checked bandwidth limiting / QoS settings on your router. I've definitely seen people accidentally have that function enabled without knowing.
I also think I've seen an Asus where a factory reset fixed weird speed issues.
In both instances it has been when the customer previously used the same Asus configuration on a VDSL / Phone line based connection then migrated to something faster. Almost like I feel either the router automatically sets it and then never re-tests, or makes it easy to set and then forget.

(Simple test would be backup your config, reset the router, retest your speed.. if problem isn't solved, restore your original config.)

Thanks, unfortunately the issue is on both routers and isn't consistent so I don't think it's that...have done factory resets on both too
 
If you can get the advertised speeds for a few hours before it drops off then it's really unlikely to be a physical issue with the fibre or PON. The fact it's a drop off on the upload suggests it's not a congestion problem either.

Do you have any close neighbours with Community Fibre?

I can see that someone on the street does based on the WiFi names I can see, I asked in our WhatsApp group but nobody confirmed unfortunately, unsure who it is...
