Asus AC66U on Plusnet - Slow internet speed

I just set this router up (using the wizard) but immediately notice the speed is very low on the internet. In fact, I did a wireless speed test on the Plusnet technicolour before setting it up and got 42mb downstairs on speedtest.net. Now with the Asus wired in it's only hitting 35mb. What's going on? I have a 78mb connection and get 70mb+ wired in normally.

The Asus router page is confusing. Where do I check my sync speed?

I have updated to the latest firmware.

The Openreach modem is handling all the sync side, the Asus has an Ethernet WAN port so no VDSL information available.

What is the MTU set to on the Asus?

MTu 1492

Maybe by coincidence my plusnet speed has dropped.

On My Plusnet account it says current line speed 78mb. But I dont know how often this refreshes or whether it's even accurate?



Edit:
Okay I've just gone on speedtest.net and it's now giving me 67mb. Maybe it was just a busy period (I ran it over 5 times and tried different servers) and it's coming back to normal. What a coincidence though that my speed plummetted within a space of 20 minutes of setting the router up?

Your original post implied you were running a wireless speed test. That immediately makes the results dubious.
