Speed permanently lowered

IngeJones — Tue, 14 Jul 2026 12:36:45 GMT

We have the 80/20 package and as of a few weeks ago we've been capped or throttled at 13 Mbps.

Which router are you using, please?

Re: Speed permanently lowered

IngeJones — Tue, 14 Jul 2026 12:42:56 GMT

TP-Link Archer VR600 v3. Tried restarts etc, checking QoS settings. There is of course the heatwave to consider but I thought it might not hurt to also check if there is anything the plusnet end on our settings.

OK. I was hoping you were going to say a PN Hub2.

As you didn't, please report a fault via: https://www.plus.net/help/report-a-problem/

checking QoS settings

Disable QoS on a domestic grade router, it can degrade the speed.

The 13 Mb/s was measured how e.g. via Wi-Fi at the end of the garden or on a direct network cable to the router ?

We have had the QoS settings for at least two years now without this problem and we do need them. Like I say it's not been a problem before

As asked above, is this via a wired or wireless speed test? Your connection stats suggest you should be getting close to the max speed.

@IngeJones do you have a STATIC IP address ?

Re: Speed permanently lowered

jab1 — Tue, 14 Jul 2026 13:45:50 GMT

@ExForce9 I don't know what relevance that has if this is a recent speed reduction?

Re: Speed permanently lowered

IngeJones — Tue, 14 Jul 2026 13:46:25 GMT

Both ethernet and wifi... which is actually a bit odd if the test is from device to test server. Even though we do have some pretty good wifi

Re: Speed permanently lowered

IngeJones — Tue, 14 Jul 2026 13:46:52 GMT

Yes we do have a static public IP

~~Are you testing on a wired connection, @IngeJones ?~~

Have you reported the issue?

As i said above, you are reporting a near perfect connection speed on a good line, so something is awry.

does your router have a useful event log?

@IngeJones

As you have a static IP, then it is possible that your Plusnet "Current Line Speed" profile has got out of step with the Openreach BRAS profile, and could cause the restriction of speed that you are experiencing.

If you login to the Plusnet Member Centre, what does your "Current Line Speed" say that is set to ?

Re: Speed permanently lowered

IngeJones — Tue, 14 Jul 2026 13:56:31 GMT

Yes I got a call back from them just now and we're pretty sure it's not something set wrong plusnet's end. I have a few more things I can try - including testing with a different router

@IngeJones

Assuming that your connection is on FASTPATH (i.e. not interleaved) your Plusnet "Current Line Speed" should be around 77300Kbps

Re: Speed permanently lowered

MisterW — Tue, 14 Jul 2026 15:01:13 GMT

@ExForce9 I dont think you can see 'Current line speed' any more! Whilst it used to still apply to accounts with static IPs, I'm not sure that's the case now

@dave / @plusnettony

Referencing this - https://community.plus.net/t5/Full-Fibre/Current-line-speed/m-p/1852275#M131636 - is the Workplace Profile still a "thing" and if it is, is it "in play" here as described in the linked to thread?

If it is not still a "thing" then the bottleneck is elsewhere: if we trust the stats reported by the router, then the link speed is excellent leaving consideration of the throttling being either something else in the PN space or something in the user's space.

@IngeJones

Switching off QoS and trying a different router might help prove or eliminate there there being an issue with the third party router.

There is though also the possibility of there being RFI leading to a significant level of data transmission failures. Remember that the "speed" test is not measuring the speed of the link, but the capability to transmit data - the are fundamentally not the same.

One can have a poor data transfer speed and a poor sync speed, which is probably indicative of a connection (to the exchange) issue
Also one can have poor data transfer speed with excellent (reported) sync speed (as here) which points to something other than a connection issue

Also try a different test device to eliminate the possibility of the issue being your device or run task manager and look at the performance graphs whilst running the speed test.

Not all speed testers are born equal - what results do other test sites report?

ExForce9 — Tue, 14 Jul 2026 15:25:58 GMT

@MisterW are Plusnet customers on static IP not routed via an L2TP tunnel any more ?

If an L2TP tunnel is run without a download IP profile restrictor, there would be all sorts of packet loss chaos.

Whether it's setting is visible to customers is another issue, but the profile restrictor must exist unless tunnel throttling is done elsewhere.

EDIT: Townman beat me to it !

Re: Speed permanently lowered

MisterW — Tue, 14 Jul 2026 15:27:54 GMT

@ExForce9 its definitely still routed via an L2TP tunnel but where/if the download profiling is done now , I'm not sure.

Certainly AFAICS there's no Current line speed visible in the account any more

I'm a bit out of touch on these issues, but I believe it is.
