Your wireless router will restore the factory settings, and then reconfigure click on it, is your router problem, something to do with the notebook

it's not the routers problem as this happens with every router i connect to, it'll just disconnect, the router name will come up on my network list but when i click 'connect' it doesnt connect, like i said this happens everywhere i go, no matter if im at home, a friends house or in a coffee shop and each time i have to restart my laptop to allow it to connect to any sort of network
