Has anyone tried using an internet stick like the Rogers Rocket stick with the Surface rt? I plugged mine into the USB - but the Connection Manager would not load. I see nothing that looks helpful at the 'store'.
Have you tried it to see if it works on another device? I don't see anything for the Rocket Stick either but the Stick could be faulty. You need to confirm it wasn't DOA.
On RT you're much better at getting a Cell Modem/WiFi Router Combo (MiFi) as most require some type of Connection Manager Software that isn't compatible with Windows RT's ARM Architecture.
