After my router has gone two weeks ago broken and could offer o2 me only expensive models, I decided to buy this device. The installation worked perfectly. First, in any case. In the manual is that one should register on the site of Netgear with the username admin and the password is password. However, this was not working. It has been repeatedly shown me that username or password are invalid. After some research to find the right data I then found it. O2 customers have as username [email protected] and enter the password FREEWAY. Now I am super happy with my device.
