strange problem

Hi

im running a home network of 3 Pc's on a cable connection.

the problem is we seems to be running out of download's quite fast compaird to normal. i have been monitoring the bandwidth of my computer for the last 40 odd days and recenty iv noticed that my pc constantly downloads 1.4KB/sec and uploads at 1.9Kb/sec this may not seem like that much but after 24 hours a day 30 days a month it adds up.

i ran netstat in command prompt and got the following
Tcp Mrcomp:3949 COLIN-9MBP8V0TY:netbios-ssn established
Tcp MRCOMP:3960 192.168.1.1:http CLOSE_WAIT

i thort it might just be transfering files between my pc and Colin-9 however when i shutdown the other Pc and disconnected it i was still Dling/uploading

not sure where exacly the info is going so i downloaded a few tools. Tcp viewer from microsoft shows svchost.exe 876 constantly chaiging ports going from port 1000 or so to 5001 then restarting over again only stoping breifly on every odd port.

i have looked around on the net about this and come up with nothing so far using google perhaps im not using the right search words.

ps i tried ending the Svchost.exe 876 via tcp viewer only to discover my music files could not be opend due to missing codecs or something both Wmp10 and classic could not play them i restarted and that fixed the problem. i ended the prosses again and the same thing happed.

pps. optuscable count downloads and uploads towards total monthly data allowance

any 1 have any susgestions or anything at all plz help
