Is it possible to get a 2.0 Mbps upload speed witha WIFI connection

[cinque8]

Hi,

I currently have a Virgin Mobile WIFI connection to my laptop and I currenlty do not have access to an ethernet connection.  Virgin Mobile uses the Sprint Network. For my job I need to make internet calls from home, but according to Speedtest.net I only have upload speed of 0.88 Mbps. http://www.speedtest.net/my-result/3644363100 Is it possible to get up to 2.0 Mbs upload speed without a wired connection?

Thanks!
