It must be something in the smart hub though, others seem to say if you remove the smart hub and use your own WiFi Access point then its fine. Hopefully one of the mod team will pick this up and resolve it like they did before.
Apparently not, so looks like the open reach modem is where the speed is set but there is some router setting that caps us at 50mbps. Once again, thanks to the team on here, I’m sorted with my upload speed though
Could do with someone on the slower provisioned line trying a third party router then. But I bet it would still run at the lower speed.
Just been reading the specification for WDM PON. It states "The OLT is responsible for allocating upstream bandwidth to the ONT"
Partly to manage possible transmission collisions between ONT's on the multiplexed upstream.
Something called physical layer operations, administrations and maintenance PLOAM messages.
Will investigate further 🙂
Ah !. When an ONT is powered up the head end uses PLOAM message to provision the ONU with a profile. This would indicate its the ONT ?
If it helps, when I first had 900 installed, I was getting 900/50 on the SH2.
I did also try a TP Link Deco M9 connected directly to the ONT and was getting 900/110. Switch back to the SH2 and straight back to 900/50. Did this back and forth a few times and was very consistently the same results.
Called BT and they said they would "change something within my profile" and after that, it was fine at 900/110 for a while. Then the FTTP decided to completely stop working, but that's a different story altogether.
