Hey, I'm currently using a Compaq Presario SR5710F Desktop PC which was running on Windows Vista Home Premium and recently upgraded to Windows 7 Ultimate. Recently my internet crashed, which unable me from connecting to the internet. Wireless connections work fine except for my computer so I figured its not the modem/router problem as how they were synced and working on other computers. I've been wondering if it was a driver issue, like my driver couldnt detect the internet due to the upgrade to windows 7. Is there a solution to this problem? Thanks for the support!
