Your speed tester is testing THROUGHPUT (end-end transfer from disc to CPU to network at the host, across the Internet and from router to CPU to disc at your end).
Traffic arrives at your house at a maximum speed of 10Mbit/sec. In practice you may find it difficult to achieve that sort of throughput because
a) the speed of your radio link depends on signal strength, with a weak signal the radio may have a lot of error checking and correction to do. I've seen 54 Mbit links run at 5 Mbit/sec in difficult conditions.
b) the throughput speed depends on the performance of the target machine; the CPU has to process all the incoming traffic and write it to disc. You may find that an old and slow laptop can't keep up.
c) there are various processing latencies e.g it takes time to find and open the file you are writing to, it takes time to write things to hard disk. It's not known as Windoze for nothing ..
It might be worth testing the download speed with the laptop near the router, that should give you an idea of whether the bottleneck is the radio link or the laptop.
HTH.

close but no cigar howard, it not the PC hardware thats the problem , iv had 386 and 486 machines pushing through 10Mbit (MegaBIT) with no problems (showing my age LOl and many people here wont even know what they look like),a 386 on a Zorro BridgeBoard card, and a 10 Mbit ISA was fun.
by far the overriding problem once you are sure your getting near the subscribed speeds your paying for with a direct RJ45 wired connection.
is the old 11g wireless routers CPU/SOC IS NOT POWERFUL ENOUGH to process the full incoming dataflow
and process the wireless security options at the same time to give anywere near the max real 22Mbit/s throughput that generic 11g can do, get yourself a new set of 11n kit and have far more CPU power to process the incoming dataflow and security options and be happy.
what is it about the Baguley NW server building, why cant they upgrade that key location sooner, doesnt the NW VM paying userbase matter to VM executives or the bottom line!
