Sometimes i had to manually restart the device.

Other: Very good gadget, it's a good solution for who want to share a 3g connection at a fixed place like you home or office.

Pros: I was surprised about how many configurations it supports, before receiving it I was little afraid of its config interface but as an geek I found no problem. It recognized the USB modem right away, and its WIFI signal while sot super powerful its really decent.

Cons: For someone without previous experience with configuration of similar gadgets might be little tricky, but no more than other gadgets alike. Too bad it doesn't get the apns directly from the carrier, so user must enter them prior of connecting. It doesn't fell THAT solid, still decent. I wouldn't risk updating firmware, nor getting any support for it from manufacturer

Other: if you need a device like this, this is a really good option.
