The new Fios Gateway Router is now available in most areas.
If you are wanting it and want to see if you can get it you can call and ask, but the easiest way it to login into your account online, go to add/change services then add/upgrade services then to Wireless Routers.
The Gateway will be listed there if it is available to you.
You can choose to buy it for $149.99 or rent it for $6.99 a month. A one time shipping fee will apply.
If needed you can view the manual and features here.
