I have an Acer Aspire 5755g running Windows 7 Ultimate 64Bit which keeps dropping the wireless connection to the internet. Sometimes it can be within minutes and other times it will happen after an hour or so.
I have tried to use a different router and using a different ISP and still with the same problem. I have tried the trouble shooter for the network and also for the whole device(machine).
Something strange is that when I have the problem and I go to restart or shut down my machine it takes a very long time to shut down and even in some cases I have to hold down the power key to force shutdown, but when I restart the machine it seems to work fine again for a little while before the same thing happens.
I have checked the drivers and everything seems fine. I cannot think of what else to try so any help would be appreciated.
