Grasshopper controller not working with usb wifi adapter?

Hi, I have both laptop and desktop.

I have the grasshopper controller app on my phone and was able to use it with the AndroidInputExample file here (http://www.grasshopper3d.com/group/ghowl/forum/topics/rhino-grassho...) on my laptop and it worked fine.

Since my desktop doesn't have wifi, I ordered a usb wifi adapter, this one to be exact http://www.ebay.co.uk/itm/300Mbps-Wireless-USB-2-0-WiFi-Network-Car...

However the exmaple file doesn't work and I get this

I guess there's a difference in the way the usb wifi works as opposed to my inbuilt laptop one. Has anyone had this problem or know a way to fix it? 

Thanks

P.s While on the subject, I am unable to use the example definition at university, which I assume is due to stricter firewall rules, but is there any other way around this other than actually getting them to change the firewall settings?
