Best wireless router with FTTC

[#1]

I have recently got FTTC and have now started the 80/20 trial, so far so good, my question is, what is the best router to use with FTTC, my 80/20 speed through ethernet cable is 47/11 but when I use the wireless it drops to 19/7. I should say I think the Plusnet service is superb, I am about 3km from the exchange and about 600mtrs to my cabinet, so my speed is fantastic 
I have the Technicolor Router, which Plusnet have swapped once due to poor wireless performance, but the new one is just the same. I don't mind going out and buying a better router if the performance will improve, so anyone got any suggestions, or should I carry on with my 60 feet of ethernet cable 
The two speedtests below are the same PC one after the other, one on wired, one on wireless

I believed I had a similar issue but I found a 'hidden' setting within Windows for my wi-fi adapter which said (something like) 'Enhanced Throughput' OFF, after turning this ON my wi-fi throughput to this laptop increased from just over 20Mb/s to well over 50Mb/s.  I would never have previously switched this OFF myself so I presume it's the default setting for that particular device / driver.
Sorry, I can't remember where exactly I found the settings but if you start in Device Manager and go from there (I'm assuming you're using Windows - apologies if that's wrong).

Thanks for the reply, I have gone through device manager and I cannot find that in the advanced settings etc, I have borrowed a neighbours Belkin N wireless adapter and tried that, little bit quicker on the down but much better on the up, bizarre
