Speed to engineer equipment at socket good - smart hub then puts out 10mbps less...

A strange one that has the engineers baffled.

The speed at the end of the DSL line, when plugged into test equipment, is around the 30-31 Mbps (slightly down on what is was before I was dropping at up to 300 times per day, 8 weeks ago. That dropout has, thankfully, been fixed).

When the DSL cable is plugged back into the router and the speeds taken, it's 20-21 Mbps. Hard wired or wifi - this speed is the same.

Engineers don't know why and 2 of them yesterday were scratching heads. Everything else checks out - line syncs correctly, cabinets working, event the top of he pole that brings the line into property is good (engineer was up there checking - small bits of corrosion, but nothing that would cause a 10 Mbps, or 30%, drop)

Two Smart Hub's are showing this issues (one new, one from 12 months ago).

I've ordered a new modem router (cheap TP Link) to see if this solves it and I can categorically demonstrate that it's the modem router that's the issue.

Wondered if any other BT customers had experienced this, and if there was something that was being missed?

Thanks

UPDATE: Re: Speed to engineer equipment at socket good - smart hub then puts out 10mbps less...

Bumping this with an update:

Tried a new modem router (TP link TD-W9970) with new cable. Speed still at 20mbps from router.

Tried a Draytek Vigor 130 VDSL modem into a router (linksys Velop mesh system) with new cable. Speed still at 20mbps from router.

This DESPITE the engineer getting 30mbps+ from the socket when running tests at the weekend.

Do any of the experts on here have any idea what's going on? Two BT engineers were left scratching their heads and I've now proved that it isn't a BT Smart Hub issue. There's SOMETHING throttling the speed after it leaves the socket (30mbps) and then a device is connected via a router (20mbps)

Any thoughts greatly appreciated.

Thanks

welcome to the BT community forum where customers help customers and only BT employees are the forum mods

in order for the forum members to help please can you post the stats from your router (if hub enter 192.168.1.254 in your browser) and if  HH5 then go to troubleshooting then helpdesk and if HH6/SH2 then advanced settings then technical log information . 

enter your phone number and post results  remember to delete number   https://www.broadbandchecker.btwholesale.com/#/ADSL

Someone may then be able to offer help/assistance/suggestions to your problem
