WiFi disconnects on shut-down, hibernation and sleep mode and won't reconnect

[Mr Marchant]

Hi everyone,
I have recently bought a new laptop and it is great! Although I have encountered a reoccurring problem that has got on my nerves and this is that whenever I shut-down or put my laptop into hibernation/sleep mode, the WiFi disconnects. I don't understand why it does this because I have it set so that it should automatically reconnect but it doesn't. When I try to manually reconnect it, it wont work and the only way I can reconnect is by turning of my router and turning it back on again, knocking out everybody's connection. I have all my drivers up to date and I don't understand why it is doing this! (My computer runs on Windows 8)
Any help would be greatly appreciated!
Thanks

Your WiFi will disconnect when you put the computer to sleep or hibernation. Try deleting the wlan profile and connect once more.
