80 / 20 Fibre Trial Issues

[#1]

Hi,
Thanks for including me on the 80 / 20 Trial.
My download speed test results never go over 18mb at best, most of the time no faster than 14mb.
Is there something blocking my connection going faster?
My upload speeds vary from 8mb to 18mb ?
The Technicolor TG582N router is now connected, but the wireless range seems to be very poor compared with the original NetGear N150 router.
Do you have another Wireless N router that I could trial?
KInd Regards

Simon

It shouldn't be that slow wirelessly, I have had 40meg using the same router running a speed test on my Galaxy S2.
How is the speed wired?
