I just tried the Pinger for the first time and want some advice. When I am trying to connect my laptop to the network its says limited connectivity, it seems I have to pull the power lead out of the router and put it back in again for the network to work correctly again.

Does the stats below have any indication as to why this might be happening?
ADSL Link Downstream Upstream
Connection Speed 12287 kbps 796 kbps
Line Attenuation 29.0 db 17.0 db
Noise Margin 12.5 db 14.5 db
