I am using Clear 4G internet. My wired computer get the same results as my wireless laptop on a speedtest - about 5.30 Mbps down and About 1.00 Mbps up with a ping between 80-160. When I do a speedtest on my iphone over Wifi, I get about 0.29 Mbps down and around 0.80 Mbps up with a ping of around 300. I don't understand. My 3G Speedtests are leaving my wifi 4G in the dust - any ideas on what is going on? P.S. Clear gives you two modems so I have one at work on a Cradlepoint router and another at home on a netgear router and they both give me the same slow results on my iphone but fast speeds on everything else!
