You are misunderstanding the capabilities of wireless connections.
Any wireless connection is only as fast as the prevailing environment around it will allow.
Also the rating of 54Mbps is what the MAXIMUM capability is, not what it will usually perform at.
[i]"My problem is that I have a 20MB internet connection and when I run a speed test (www.speedtest.net) I get very odd results.
If i am wired directly to Modem - 19800MB
IF I am wired to the router - 15500MB
If my I use my wireless connection - 5400MB very very little."[/i]
For a start, you have to heed the difference between Megabytes and Kilobits - each of your quoted speeds should be Kb, not MB. You have posted with speeds that are instantly 10x^3x8 above reality. ;)
Personally, I am sitting in the Scottish Highlands on a supposed 8MB connection, and my Speedtest.net result has just come back as: [b]6,197Kbps download / 304Kbps upload[/b] - I am content with that, given the local time and my geographical location. If I were located in Glasgow or London I might complain with this speed result, [i]then again I'd probably not [b]unless it really mattered.[/i][/b]
My Speedtest.net score of 6,197 is for Kbps, so to figure out my MBps score I divide it by 800, which comes out at [b]7.74MBps[/b]
Your score of 19,800Kbps comes out at [b]24.75MBps![/b]
[b]THAT is why I don't believe your figures - you are getting 25% MORE speed than you are quoting you SHOULD be getting - and you're still complaining! [/b] :^0
Your Speedtest results should be checked again.
[u]You have effectively just shot yourself in the foot![/u] ;)
What are you using your system for?
Why are you SO concerned about the figures coming back from Speedtest.net?
Were you concerned BEFORE you knew the figures? ;)
Remember - a little knowledge is a very dangerous thing. ;)
And never forget that there are EIGHT bits in a byte, a thousand bytes in a kilobyte, a thousand kilobytes in a megabyte.

You would do well to learn the subject of wireless and transmission speeds in general, before you go off at a tangent again.
