I own an airport extreme base station and realized that I really wasn't making it run at its optimal speed... so i changed the wireless settings for it to run at 802.11n (5GHz) only. My problem now is that my computer is running fast, but my iphone cant connect to the network... so does anyone have any ideas to fix this? I'd like to keep the settings... so I was thinking about maybe buying an airport express to plug into my extreme to send out a g signal so my iphone can pick it up... anyone have any better ideas?
