I guess I'm having the same problem too. I have a PC and a laptopn at home.
One running on VIsta and the other XP, both on the same desk but showing
'good' for Vista and 'excellent' for XP. I don't understand why. I tried
every solution found on the internet and nothing works. I'm using LInksys
WCG200 Cable Gateway, tried resolving the issue with Microsoft and HP here in
SIngapore, and none can come up with any solution. Suprisingly, they don't
even know of this issue at all! AFter much research on the internet, I found
many users having the same problem. I raised it up to them and they will look
into it. Till today I'm still waiting for thier phonecall. In the meantime, I
just have to sit and live with this slow connectivity which is driving me
crazy. I wouldn't have upgraded if this issue was made known to me....
