New TP-Link AC1200 aka Archer D5: 50% slower???

[link to this post]

I recently switched to this combined router/modem from my old NetGear DG834PN to get better wireless and WPS, but I can't seem to get it configured properly.

That is, it works, but I've lost bandwidth by a significant margin.

Switching back and forth between the DG834 and the new one, I see the following, on average:

DG834 AC1200

Thinkbroadband TBB 9Mbps 4.5Mbps

Thinkbroadband HTTP x 6 10Mbps 9Mbps

BT BTP 11Mbps 8Mbps

scp [file transfer] 1MBps 500KBps

The BT site has so far been unwilling or unable to run the Further Diagnostics for me -- my exchange is Donaldsons, in Edinburgh.

I have a wired connection to the machine running the tests (using Chrome browser, Windows 7) and both devices report essentially the same "in principle" bandwidth:

Upstream Downstream
Current Rate (Kbps) 1272 10899
Max Rate (Kbps) 1343 12128
Upstream tests the same 1Mbps via both devices for both test programs.

I've tried both the TP-link wizard config and using Zen's recommended settings for 3rd-party routers, can't see much if any difference there, and no difference in performance.

Anyone else out there with experience of TP-Link boxes, or suggestions of where in the configuration I might look to find out what's wrong?

MTU?

My broadband basic info/help site - www.robertos.me.uk | Domains,site and mail hosting - Tsohost.
Connection - Plusnet UnLim Fibre (FTTC). Sync ~ 56.6/14.1Mbps @ 600m. - BQM

1492 in both cases (original default was 1480 on new box, raised it manually to where I believe I had increased it for the old one), but that was done years ago -- what's the preferred setting nowadays?

That's what I'm on, on FTTC.

If both routers are 1492 as you say then that isn't the problem.
