so I have an Asus laptop with windows vista and everytime I go on, usually anywhere from 20 minutes to 3 hours after its on the internet will stop working, yet it still says im connected to the internet. so its not the internet its the computer. and then the problem is fixed if i turn the computer off and back on then i can access the browser again. However, once my computer blocks the internet it takes it a lot longer than usual to turn off, sometimes it just stays stuck at the "shutting down" screen and will never shut down. so basically how the hell can this be fixed? it gets annoying.
