Lately my Acer laptop with Windows 7 Home Premium 64 bit is very slow to connect to wi-fi away from home. It won't show connections, so then I open the network and sharing center and it's blank when I open it. I have to use task manager to close it, this causes windows to stop working. After windows restarts I can connect but it has to go through this routine every time I'm away from home.
Could this be related to being set to connect automatically to my home connection which not in range at that time?
