If your internet has been running into problems
I suggest you reset it for about 5 minutes
unplug the power cord on your modem, and if you have a wireless router, that too.
Unplug all of the connections in the modem+wireless router.
leave them alone for 5 minutes or so
ReConnect all cords, and then before you start surfing online
Go to Network Connections, Right Click on your connection that you're using
Click Disable
Then Enable,
then repair
Works for me all the time.
