10.0.0.1 — Comcast & Xfinity Gateway Login
The default admin gateway for Comcast and Xfinity-supplied routers. XB6/XB7/XB8 owners must enable access via the Xfinity App first before 10.0.0.1 will open.
What Is 10.0.0.1?
10.0.0.1 is a private IPv4 gateway address from the Class A range (10.0.0.0/8) defined by RFC 1918. Comcast chose this range for their gateways because it supports a far larger number of local device addresses than the 192.168.x.x range used by most home routers.
If your internet service is provided by Comcast or Xfinity and you are using their supplied gateway hardware, typing 10.0.0.1 in a browser opens the router admin panel where you can manage Wi-Fi, set up port forwarding, and check connected devices.
XB6, XB7, XB8 owners: Comcast disabled the web admin panel on these newer gateways by default. Before trying 10.0.0.1, open the Xfinity App → Wi-Fi → View Wi-Fi Equipment → Advanced Settings → Admin Tool Online Access → toggle ON. Then 10.0.0.1 will load.
Comcast/Xfinity residential gateways: Arris TG1682G, TG3482G (XB6), TG4482 (XB7), CG7486E (XB8). Also Technicolor TC8717T and Cisco DPC3939B.
XB6 and newer require the Xfinity App to re-enable browser admin access. Older Arris units (TG1682G) work directly at 10.0.0.1.
10.0.0.1 is not reachable from the internet. You must be connected to your home network via Wi-Fi or Ethernet.
LPB Piso WiFi coin-operated hotspot systems use 10.0.0.1 with default credentials admin / 123456789.
How to Log In to 10.0.0.1
- XB6/XB7/XB8 only: Open the Xfinity App → Wi-Fi tab → View Wi-Fi Equipment → Advanced Settings → Admin Tool Online Access → toggle ON → Save. Skip this step for older Arris models.
- Connect via Ethernet by plugging a cable from your computer into one of the yellow LAN ports on the gateway. Ethernet is more reliable than Wi-Fi for admin access.
- Open a browser and go to
http://10.0.0.1. Type this exactly in the address bar with the http:// prefix. - Enter your credentials. Default for most Comcast gateways: username
admin, passwordpassword. The exact values are printed on the sticker on the back or bottom of your gateway — look for a label called "Admin Password" which is different from the Wi-Fi password. - Change the admin password under Gateway → At a Glance or Connection settings after your first login.
Common typos that will not work: 10.0.0.0.1, 10.0.01, 1.0.0.0.1, or 10.0.o.1 (letter O). The address always uses four numbers separated by dots.

| Arris XB6 / TG3482G | admin | password | Enable via Xfinity App first |
| Arris XB7 / XB8 | admin | password | Enable via Xfinity App first |
| Technicolor TC8717T | admin | admin | Some units use sticker value |
| Cisco DPC3939B | admin | password | — |
| LPB Piso WiFi | admin | 123456789 | Some units: administrator / admin1234 |
Troubleshooting 10.0.0.1
Open the Xfinity App → Wi-Fi → View Wi-Fi Equipment → Advanced Settings → Admin Tool Online Access → toggle ON. This is required on all gateways from XB6 onwards before the web panel will respond.
Some Comcast gateways only allow admin access over a wired connection. Plug a cable directly into a yellow LAN port and try again before assuming there is a bigger problem.
On Windows, run ipconfig in Command Prompt. Look for Default Gateway. Some Arris units or custom configs may use a different IP such as 192.168.0.1. Use whatever the ipconfig result shows.
VPNs block local network access. Disconnect completely, then open an incognito window and try http://10.0.0.1.
Unplug the power cable, wait 60 seconds (cable modems take longer than regular routers), then plug back in and wait 3 minutes before trying again.
Hold the recessed reset button with a paperclip for 30 seconds until all LEDs cycle off. Default credentials restore. All custom Wi-Fi settings will be erased.

Frequently Asked Questions
Why did Comcast disable the web admin panel on newer gateways?
Comcast moved toward app-based management to reduce support calls from customers accidentally misconfiguring their routers. The Xfinity App provides a controlled interface. You can still re-enable browser-based access via the app under Advanced Settings — Admin Tool Online Access. If the toggle is not visible, your gateway may be in bridge mode, in which case you need to contact Xfinity support.
What is the difference between the admin password and the Wi-Fi password on a Comcast gateway?
The Wi-Fi password is what your devices use to connect to the wireless network. The admin password is what you enter at 10.0.0.1 to access the gateway settings panel. They are completely separate. Comcast prints both on the sticker on the back of the gateway, usually labeled clearly. Never share your admin password with anyone you would not trust with full control of your router.
Should I buy my own modem instead of renting from Comcast?
For most households, buying your own is financially sensible. Comcast charges around $14 per month for gateway rental. A quality DOCSIS 3.1 modem like the Arris SB8200 costs around $100 and pays for itself in under a year. You also get full admin access without any Comcast restrictions and avoid the ongoing rental fee.
