I have noticed slower page loading times in the last few days but my down steam connection has stayed at 4.4mb.

3 Wireless devices
ADSL Link Downstream Upstream
Connection Speed 4479 kbps 796 kbps
Line Attenuation 48.0 db 26.2 db
Noise Margin 5.4 db 11.5 db

Extra note: We have our wireless set on channel 12 because we were told by sky this was the fastest (We were told 11 before- Cant make their mind up)
