take the router out of the mix...for a test..direct from the modem...
I wasnt sure if it was a fresh install or not..
could be the isp for that matter... too much junk on the line..
Cant really take it to another location very easy either....hmmmm.
let us know about the router...that would still leave the isp at question too..
maybe take the laptop to a different location..different isp....as a test.
If that is a fresh install, all virus software reports-clean, hijackThis?...
9 times out of 10...It is something in this, and look over installed programs..make
sure nothing slipped in there on ya...
then...you know the rest..hehe...router,isp.
There is alot of junk making its way to (win7/xp/vista) c:\users\[YourUserName]\AppData (You have to enable view in FolderOptions)\ Then check that folder content and the three folders in it, Local,LocalNow,Roaming for ANY exe's ....
also check all temp folders for exe's................... virus scans seldom find these.
We have all seen them..ie: the one that locks computer saying you have a virus (yea, them)...that is where
that is.... if you can get into safeMode..
This was a lil off topic...good info though... Some made a few thousand dollars last year fixing these..ehhehee..I wont say who.hehehe.
Im really thinking its not your setup....drivers, ect....but, love but, I could be wrong..thats why its called troubleshooting..its blind..lol.c.
