As for latency, wireless network will definitely have a much higher latency than wired no matter how quick the speed can be. Games should stay away from wireless internet as there will be spikes in ping times and it will be affected by environmental factors. (Eg, temperature, humidity, atmospheric pressure) as this technology uses wavelength over air, those factors will affect the performance. Try going to USA and use a satallite based internet connection, the latency is high (at least 100ms) but the speed is great.
