Hey,
ive got a bit of a problem with my net speed, usually i get atleast 500kb/s download speed, and the router shows up me having 5364kbit (or thereabouts) internet speed. however over the past few weeks i have notices a drop down to only 200kb/s (router shows 2048), and i was wondering if anybody knew why thing could be. here are the stats shown in teh firmware:

Connection Speed 2048 kbps 448 kbps
Line Attenuation 43.0 db 27.0 db
Noise Margin 6.7 db 18.0 db
