Use Apple's Reachability class to check for Wifi or WAN. Use this example and code: http://developer.apple.com/library/ios/#samplecode/Reachability/index.html

Checking the speed is more difficult, you would need to measure it by your own I think, maybe the best way is to ping and measure the response latency.
