Summary: On receiving the router, as I have never had a router before, I was expecting it to be difficult to set up. But, it was so simple to install that I was confused. Some of the terminology and abbreviations left me lost. But, once I spoke to my USB modem provider and had an email reply from Edimax customer support I was away.
Summary: I've been using this device for a couple of weeks now, while travelling, to turn wired internet connections (mostly in hotel rooms) into WiFi fo use with smartphone and iPad. I haven't yet tried the 3G USB option. It's compact and easy to set up and "just works", giving a strong 11n signal. Excellent value compared with data roaming on 3G! Even the manual (PDF version, not the paper instructions) is good.
