On the edge of glory.
I've used the Magic Kingdom Wifi a few times since it went live, but I couldn't get it to work at all tonight. I tried several different tasks in several different locations and I got no results. I thought maybe there was high traffic, so I also tried after the park closed in areas that were basically deserted and I still had bad results. So let's get the wifi working before we start expanding it, shall we?
I was having the same issue on Friday nighT at MK. My iPhone kept trying to default back to 3G because the wifi connection was so bad.
