keep losing wireless connection

I have a MSI CR720 laptop, fot the last few months i have been losing my wireless connection. Sometimes the connection it will last for a few weeks and another i will lose it so many times in one night i will just put it away.
I have reloaded win7 thinking corrupted drivers, no difference.
The password is correct even though when the laptop has lost the password and i re input it, it tells me it is wrong (it's not)
Today i have reloaded win7 yet again, this time i did not load the wireless and network drivers. I installed driver genius and it found 'new' drivers, these were installed.............success!!...........for an hour.
Rebooted laptop and all worked again after reentering the router passkey, still going for 15mins now but who knows, could really do with some pointers please
