My internet connection is always on, it says that the signal is perfect, but every 5 minutes, I cannot open anything. Skype doesn't open, neither Internet explorer, but the signal is still excellent. Please help! How can I fix this! By the way, I recently reinstalled my Windows and since this has been occurring. Thank you very much!
Programs wouldn't stop opening because of your net. It's more than likely an issue with something running on your machine.
Do a virus/adware scan, and make sure running applications aren't blocking them.
