Does AT&T fiber use a router?
It is important to note that AT&T fiber internet service does necessitate the use of a router within the home environment. AT&T fiber subscribers are given an Arris model BGW210, 320, or 10 wifi gateway router combo unit when signing up. It also functions as the fiber optic terminal and helps to connect your devices to the internet through wireless or wire connections.
The AT&T Fiber Router
AT&T fiber routers, which are received from AT&T, contain the fiber optic terminal functionality in one device combined with a wireless router. Common models are:
- Arris BGW210 – This is an entry-level model with 802.11n wireless.
- Arris BGW320 – mid-range device that supports faster 802.11ac wireless
- Arris BGW10 – it is the latest model of the high-end line with WiFi 6 wireless compatibility.
These routers have numerous wired LAN ports for use in connecting your wired gadgets via cables besides the internal wireless LAN for connecting your wireless gadgets.
It caters to basic tasks such as Dynamic Host Configuration Protocol (DHCP), Network Address Translation (NAT), Firewall security, WiFi encryption, and access control. Some of the models of routers that AT&T uses also incorporate an ADSL modem in case there is a need for connection via phone lines.
Is it necessary to use an AT&T-supplied router?
AT&T demands one of their routers to be used because it comes with the fiber optic terminal adapter to connect their fiber network. However, if you already have your WiFi router or a mesh system, you will require an AT&T gateway router to act as the end-point for the fiber optic cable. But you can place your AT&T gateway into IP passthrough mode to utilize your router on your home network behind the AT&T equipment.
Can I Bring My Router Into A Hotspot?
It will be possible for you to use your wireless router, but their fiber line will require an intermediary equipment from AT&T known as a fiber gateway. The options are:
1. Do not use any other router for routing, WiFi, and networking but the AT&T router. This is the easiest among the four options and does not necessitate the use of equipment other than a cell phone. However, you may not have all the basic features or even WiFi capabilities as some high-end consumer routers.
2. To configure, make sure that the AT&T gateway has the option to toggle the IP passthrough mode so that it will forward the external connection directly to the WAN port of the second router for the LAN and wireless management but still have the necessary modem/ONT capabilities. Instructions vary depending on the specific model of AT&T.
3. Plug your wireless router into one of the LAN ports on the AT&T gateway and if possible, turn off wireless on their router. It is a very similar configuration to #2 but some AT&T routers do not have an IP passthrough feature hence plugging into a LAN port does the job.
Some Tips For Using Your Router
- For information on how to set up your particular model of AT&T gateway and place the device in IP passthrough, you should consult the guidelines that specifically apply to your model.
- If passthrough is not available, connect your WAN port to the AT&T router LAN ports.
- Configure your router with a fixed IP address of the gateway subnet.
- Turn off WiFi and DHCP on the AT&T device
- Have separate SSIDs for the tablet and another WiFi password from the AT&T device.
Additional AT&T Router Functions
In addition to the router and access point functions, AT&T gateways often include additional capabilities such as: In addition to the router and access point functions, AT&T gateways often include additional capabilities such as:
- Modem that supports VDSL/ADSL to connect over the phone line.
- Fiber optic connectivity through Optical Network Terminal (ONT)
- Technical tools such as remote access, and usage monitoring are some of the tools identified in the network analysis.
- Home security and smart home integration
- Extra ethernet ports to add more computers to your wired network
- USB ports to access and share files and documents on a network, as well as to connect multiple printers.
So in summary, yes, AT&T fiber subscribers are obligated to use an AT&T-supplied gateway/router combo device. But you have the option to connect your own WiFi router or mesh system along with the AT&T equipment to have the desired flexibility in home network usage. The AT&T router needs to stay on for the fiber line termination, but you can turn off most of the features except the ONT modules.
