Horrible experience with Japan-wireless. Received a defective Mifi router. It can happen right? The problem was the useless technical support.
The router wouldn't give any DHCP lease even if I was able to connect to the wifi with the correct wep key. Customer service kept sending me instructions on how to log on to the router to change some settings. How would you do that with no Ip address!!! anyway, it took 3 days for them to finally ask me to return the defective modem and promised to reimburse me the total amount.
I decided to try global advance communication which was a little bit more expensive. Wow. I ordered around 10ish am. Modem was waiting for me at the hotel reception around 2pm same day during a public holiday nevertheless... Everything worked perfectly out of the box. Speed is awesome. Big thumbs up.
