Hi Ryan, I would suggest you to reinstall the wireless card driver on the system. Please let me know the wireless card on your system so that I could suggest you the correct driver or please enter your service tag # on the link below, select the Operating system and download the Wireless card from Network section.

 Recently I've been having an issue with my computer. I use it for school  and some games I play. Recently I have been unable to do anything on my computer for more than an hour without my internet turning itself of. In order to get it working again I have to restart it. This has become a pain and I'd like some help figuring this out. I have tried F2 but it,doesn't help my wireless is still turned of. I would like to know if it's just my computer and possible if getting a new wireless card would help. When I first got my computer I had no problem with it so it's just recently that it's happened so it's not a factory defect can somebody give me some troubleshooting options to try and fix this? Ryan,
