I have a
Medion MD98200 6379 Pentium dual-core T2060 1.66GHz processor 2.0GB DDR2 laptop running Vista Home Premium connected through an inbuilt Atheros AR5007UG wifi and a Netgear DG834G router to VirginNetBroadband.
Sometimes (like now) BBC videos run spasmodically, 6 seconds at a time with 20 secs buffering between.
Sometimes rebooting rectifies the situation (for a few videos then it bogs-down again). Sometimes rebooting the router works, but not always.
Youtube videos play normally.
Speedtest gives 300ms ping, 1.5 mbps download and 300 kbps upload.
Memory usage 56%, CPU generally 20% (occasional 80% bursts).
Download helper doesn't work with BBC videos.
Any guidance?
