A few months ago I purchased a simultaneous G/N wireless router and my laptop being the latest Macbook Pro, which supports N. What I've been experiencing is my laptop no longer being able to see my N network. I would have to either change the N password type (on the router) or re-add the N network from scratch via Lion for it to work again. At times, I've also noticed the N network not showing up at all. The G network works like a champ, but something strange is going on with the N. I don't know if it's my router or Lion that's causing this inconsistent behavior. Since I don't have another N capable device, it's hard for me to determine the cause. Just wondering if anyone else has had this issue.
