|My laptop has been doing the same! I have an Acer laptop. Turn off wifi before shutting your computer down (you might have a function key or something to do this with). Once you restart your computer your wifi will be off, just use those functions keys to turn it back on and it should connect without freezing, or at least not as much. That works for me, but you have to turn the wifi on and off all the time. It's annoying...|
I made a post asking why it does this... I'm also waiting for a reply.
