Download speed consistent but below connection speed

[DragonQ]

Since moving home, my TP-Link Archer VR900 router now connects at 71.9 Mb/s downstream (see screenshot below). However, every time I do a speed test (I've tried several websites), my download speed consistently maxes out at 58 Mb/s. This is the same regardless of connection method or machine (WiFi, router Ethernet, Ethernet via switch, Ethernet via patch panel and switch) and doesn't seem to change depending on the time of day either.

Any tips on troubleshooting this?

Is it the same on the test socket?

How long have you had the line? It can take ~2 weeks for them to settle, I assume this is the same with VDSL.

Have you done speed tests locally on your network using something like iperf? VDSL doesn't normally take a long time to come up to full speed.

Haven't tried the test socket yet. I originally had a standard ISP DSL filter attached to the master socket, and I was getting sync speeds of 60-65 Mb/s. I've since replaced that with an NTE5 Mk3 filtered faceplate and have gotten 70+ Mb/s sync speeds since.

About 3 days.

iPerf shows a steady 940-950 Mb/s between wired PCs.

Get the IP profile.

I spoke to someone at Plusnet and he said the profile they were using was a few days old, so although the router was connecting at 70+ Mb/s, at their end it was still set to 60 Mb/s. He increased it and I've rebooted the router. BT's line speed checker now says my IP profile is 71.81 Mbps for download, 20 Mb/s for upload, and I get ~70 Mb/s download in speed tests instead of ~58 Mb/s.

He also said it may get faster over the next week and that I should avoid rebooting my router between now and then.

Nice!
