Thanks for the reply qas.
I checked the link speed before posting and windows was reporting 130Mbps, however after your reply I checked what the router was reporting and it varies. channel width 20 MHz so 130Mbps is max, when it's set to 40 MHz throughput really low, about 5Mbps.
The wireless PC and router are on the ground floor about 8Meters apart with 2 doors inbetween them..
If both doors are shut:
Router Link Speed: 78Mbps - Pc Link Speed: 104Mbps
If both doors are open:
Router Link Speed: 117Mbps - Pc Link Speed: 130Mbps
If PC is next to router:
Router Link Speed: 130Mbps - Pc Link Speed: 130Mbps
Throughput is at max when PC is right next to router, it's reduced when in the back room and even worse when the doors are shut.
The range for decent speeds is shocking, annoyingly I forgot to try the channel width at 40 MHz when I moved the PC next to the router, it would probably run at full speed though seen as it does at 20 MHz.
There is an xbox upstair on the other side of the house which has no problem connecting so I think the wireless adaptor isn't good enough rather than the router haveing poor range.
How do I fix this then? I'm thinking a new adaptor or higher gain antenas for the router or even both for belt and braces, that maybe overkill though.
This one gets a good review from someone who replaced their TP-Link adaptor:

Thanks for the reply Hom3r,
I've verified the speedtest.net results, that is another good tester though, it's one of the alternatives I use to verify results.
How much of that 900Mb can you acheive and with which adaptor?
I've got a 10 year old Socket A backup system that can acheive these speeds, as long as you have your TCP settings set correctly the OS isn't a limiting factor either.
