Ok, from your past posts... you have cable, you are connected wirelessly to your router, and it is now slower that it was before you moved the PC. I hope this is all correct..
Cable internet is USUALLY faster than ADSL. DSL is one user per DSL across the phone line. Cable internet on the other hand is somewhat shared. If a lot of epople in your area have cable, and are using it... it will have anoticable effect on your speeds. That may be why your connection is so slow as sompared to your GF.
BUT, the reason your speed has dropped since the move (54MBps to 24MBps to 20). Your wireless connection in your new spot is bad. You eityher are further from your router, or cement walls (in jail?), also metal interior walls... Anyway, you have 4 options.
-Leave it the same
-Run a cat 5 cable from the router to your computer. You will always get the maximum speed that your isp can offer. It will have no wireless connection.
-Move your computer to a better spot, move the router to a better spot.
-Buy one of these and move it yo an area where you get a better connection.

You dont need the extension, but if it gets you a better signal, it is a good idea.
