FTTP - 500 to 900 Upgrade - Slowness Since Upgrade

Dialupp — Thu, 08 Sep 2022 14:24:17 GMT

I've read a few posts where others are having issues where they get slow upload speeds after being upgraded. It sounds like a profile mismatch so wondering if someone can tell me what I need to get this looked into.

Since being upgraded my download speeds have improved but not the full 900, and my uploads are pegged at 70Mbps. I also feel the realtime speed/use is slower than the 500Mbps as if there is a mismatch somewhere. I was even watching a single 4K stream on Netflix the other night and it kept jumping down to 1080p (all hard wired devices).

For information i'm using my own router (Unifi UDM Pro), it's been 5-6 days now since being upgraded, all test equipment hard wired and both ONT & router has been rebooted several times.

Have you got "Smart Queues" turned on ?

What are your speeds like on speedtest.net ?

Smart queues are turned off. Speedtest rusults vary but generally sit around 700 down and max out at 70 up.

My ping is also double what I used to see.

Do you have any threat management turned on to detect , or detect and block or it turned off ?

Here is mine with Detect & Block (medium sensitivity)..

Detect only (medium sensitivity) ..

Off ..

Normally I do, but I've turned it off.

I'm in the process of wiping the UDM-Pro. So far it's looking positive as in the download speed is now 920Mbps (solid) but he upload is still pegged at 70Mbps. It flips up to 110-120 for a blink of an eye then down to 70 again.... Small progress I guess.

My upload won't budge... Download has improved.

I just need to sort out the upload now.... For a brief second it hits around 111Mbps upload then drops down to around 70Mbps. Accessing my NAS remotly or streaming Plex out of the house is almost impossible now. Fairly confident it's an Openreach setting as it was fine on the 500 package.

Another test this morning. It's consistently in this range.

Hi @Dialupp, sorry you're not seeing the full upload.

Please would you connect up the Smart Hub and post the stats from that. We may also need you to connect the Smart Hub again if we need to help you further with this.

Cheers

John

Connected BT Smarthub and it's the same. No change (technically speedtest should be faster as no one else is connected to this router while I did this test).

@Dialupp

This post may explain the reason, as you are sharing the upload backhaul of 1.2Gb with up to 32 other users, so if they are doing a lot of uploading, then that will reduce your upload speed.

I do not think that BT guarantee upload speeds.

Testing 2 of my neighbours today and they all consistently get 110-120Mbps upload. On the phone to BT now and they've confirmed a fault and sending an engineer. Fingers crossed it'll be resolved soon.

Quick update. As if by magic, at the weekend the upload jumped to where it should of been.

Hi @Dialupp and thanks for letting us know your upload has improved.

Out of interest can you just confirm how long is it since you were activated until the upload changed?

Cheers

David

It was about 3 months if I remember correctly.
