I know for sure its not the wireless networks, because for example, I'll loose connection and my brother will attempt to use his laptop and he'll be just fine and he won't loose connection. why could this be???
It doesn't matter which wireless network it is, whether it be mine, my neighbor's, or someone else's I'll log into the wireless network then loose connection a little later and I'll have to either click "Repair" under the wireless network preferences or log in to another network.
Why does my computer loose connection to wireless networks?
