Hi @chillyelmo
Assuming those test results were via an ethernet cable, this is still below the estimates for your line so I'd concur with my colleagues earlier posts that this may be worth raising a fault for here.
Could you please let us know when you've done this so that we can get this escalated on your behalf?
Thanks
Dave

Thanks for getting back to us @chillyelmo
From what I can see the results you've got via the ThinkBroadband speedtester are fine for your downstream sync rate of 76mbps and upstream sync rate of 20mbps which are within your speed estimates as below:
Featured Products |
Downstream Line Rate(Mbps) |
Upstream Line Rate(Mbps) |
||
---|---|---|---|---|
High | Low | High | Low | |
VDSL Range A (Clean) | 80 | 76.1 | 20 | 19 |
It's likely that the BT speedtester has just thrown out another unreliable result on this occasion.

I'm just going off the speeds you've said here along with the speeds your router is in sync at.
For a sync rate of 76mbps which is within/on the bottom end of your estimates, a throughput of 68mbps is perfectly normal. When your speeds drop to 26mbps is that on an ethernet connection and are there any devices using the internet?

Thanks for getting back to us.
I'd personally say that 68mbps throughput you've shown in your post 30 is OK for a sync rate of 76mbps. If you can complete the further diagnostics of the BT speedtester making sure this is still over an ethernet connection with nothing running in the background or on any other devices we can look into this further.
With regards to your slow WiFi speeds I'm afraid that this would be a separate issue and isn't something that we'd consider a fault with the service. What do your speeds look like on the 2.4GHz frequency with the 5GHz switched off?

Well I've been told I'm guaranteed 72mbps so which is it?

We're not seeing any logged performance test results on the BT systems I'm afraid.
Are you able to carry the further diagnostics out again also posting a screenshot of the results here?

Thanks for getting back to us.
Your speed estimates/expectations of your line are between 76mbps and 80mbps however this is mostly based on your sync rate which is 76mbps unfortunately at the very bottom of the estimated speed range.
Are you able to post up a screenshot of the further diagnostics you've run?

Thanks @chillyelmo I've been looking at this with my colleague @MatthewWheeler and that speed looks perfectly fine. The max achievable of 70mbps you're seeing would be, because the IP profile of the line is set at that for the sync rate of 76mbps. Your throughput of 66mbps is on target, you'd rarely get exactly what your line sync's at.
Are you seeing any performance issues at all?

As per my previous response,

This will narrow down where the issue may lie, if you're just having speed issues using the 5GHz frequency you may be affected by the issue that's being discussed Here.
