Hi, my computer recently began to drop connection to the internet, and im not really sure why. Nothing was installed, nothing was altered on the computer, and the connection varies. Sometimes it will stay connected for a day, other times for only 5 minutes. Whenever it drops its connection it says it is trying to aquire the network but it never does. Restarting, unplugging everything, and turning things off do not work. I have a dsl router that is hooked up to something that allows 3 computers to be on the internet. My computer is hooked up to this "hub" thing with an ethernet cable. I also have recently had problems with explorer.exe not running and sometimes i have to manually turn off the computer a few times to get it to start. Thanks for any help and let me know if you need more information.
