The Background
I know this is not a NTL Question but I thought I might ask if anyone has come across such a thing as its puzzling me tbh. Now the background, I am on NTL Cable modem (Sb4100) connected via a router (rj45) to a swtich to my machines. My Mate though went for a Bt ADSL Connection and got supplied with a BT Voyager 105 USb Modem. He only has one machine, a Laptop and modem plugs into that.
Specs for his laptop btw are P4 3.06Ghz, 512 meg ram, GeForce5600 64Meg ram.

The Problem
If he is talking on Skype (voice chat s/w) to me and he then tries to play a online game (MOHAA) he lags in game. If say he starts downloading a file while we are chatting skype has a mega delay (5-10 secs maybe) and his voice breaks up. The second he stops downloading Skype returns to normal. If he plays games without doing anything else network wise (even checking email) then he is fine.

Further Tests
When He came over to my house at Xmas time, he connected his laptop to my network, were were both only both in Skype chatting to someone else but also playng various online games without a single problem with any lag whatsoever. I checked and re-checked his machine for Virus, Spyware etc.

What I am trying to work out is this basically, is the problem to do with USB Modem (he has or thinks he has latest drivers) - does anyone who ran on USB NTL CM have these probelms? Is the problem maybe with BT?

Why do i find this odd?
If i am talking on Skype myself it takes up 4k and download or upload can only take what is left - in the case of Uploads (im on 750/128) - this uploads at 9-10k. Taking 4k away from a 512 or 750 connection should not really impact it that much and it does not with me. Does USB have a feature that sucks up all the bandwidth no matter what?

I am def betting on the USB side of life tbh - I have advised him to get a Wireless ADSL router (he has wireless already built into laptop) and also when April comes and his 12 months are up - move away from BT. Anybody any insight why his rig does all of the above?
