Okay, I have an odd issue which I was wondering if anyone else has noticed. I've had Developer Preview 5 installed since it came out a week or so ago and haven't noticed this issue until today. For some reason, any WiFi network I connect to is experiencing super slow (or nonexistent) speeds on certain network functions. For example, Safari, Mail, Messages, Dropbox, etc. will appear to be connecting but just time out whereas I can use Chrome or Safari through my VM Fusion 10.7 install. It's really odd, it's as if certain services are being blocked for some reason. I'm showing a valid network connection and I'm not getting an immediate non-connection message, it's more like everything thinks it is connected but just never receives any data. At the same time Safari is attempting to load, Chrome will load up a website immediately without issue. I've tried a couple of different networks now in different locations, both with the same result. Anyone else seen this?
