Hi. I new here and new with windows 7, I search and found many similar problems but nothing help me. I install windows 7 few days ago, all fine, but last two days I have problems to connect to youtube and another sites, rapidshare, First I think problem with internet provider, connection, router, but nothing, I have another notebook at my side, my actual it's a Dell Latitude D630, my olde at my side it's a Dell Inspiron 700m (with Windows XP). From Windows XP (Inspito 700m) no problem to conects to this site, from D630 (Windows 7) don't conect, I try with many "browsers" but nothing, If I try conect to YOUTUBE I see the page, but video late many minutes and finally work. in XP for another hand, video start well. Connection see's fine, I have acces to mail, web, only few sites with VIDEO or LARGE FILES (Rapidshare) have problems.. I have another Hard Disk with XP to this computer, try and work great, I belive it's problem with driver, but no 100% secure. Anybody have similar problems with some sites, YOUTUBE or BIG FILES!!!! Thank's for your help..
