What Is 10.0.0.1?
10.0.0.1 is a private IPv4 address used as the default gateway IP on many routers and ISP-branded modems, especially Xfinity/Comcast gateways, some Technicolor and Cisco devices, and smaller business routers. When you type 10.0.0.1 into your browser’s address bar on a device connected to that router, you’re trying to open the router’s admin panel (web interface).
How to Log In to 10.0.0.1?
Follow this flow exactly; skipping steps is usually why people get stuck.
- Connect to the Router First
- Open a Browser
- Type the Address Exactly
- Enter Admin Username and Password
- Click Login / Sign In

Default Username and Password for 10.0.0.1
Different brands ship with different defaults, but for routers using 10.0.0.1 as gateway, these are the most common combos.
Most Common Default Logins
| Username | Password |
|---|---|
| admin | admin |
| admin | password |
| admin | (blank) |
| (blank) | admin |
For Xfinity/Comcast gateways, the usual default is:
| Username | Password |
|---|---|
| admin | password |
Some ISP or business-branded devices use:
| Username | Password |
|---|---|
| cusadmin | highspeed |
| admin | printed on router label (admin password / access key) |
If none of these work, always check:
- The sticker on the bottom/back of the router—it often lists the factory admin password and WiFi key.
- ISP documentation or welcome email if the router was preconfigured.
If even those fail, the password has almost certainly been changed and you’ll need a factory reset (covered below).
What You Can Do After Login
Once you’re inside the 10.0.0.1 admin interface, you can typically:
- Change WiFi name (SSID) and WiFi password.
- Switch security mode (WPA2/WPA3).
- Configure guest networks.
- Set parental controls or website blocking.
- Do port forwarding, change DNS, or tweak QoS (advanced users).
Every brand skins the interface differently, but the basics are always under something like Wireless, WiFi, or Gateway → Connection → Wi-Fi (on Xfinity).

Issues with 10.0.0.1 (Common Problems & Fixes)
1. 10.0.0.1 Page Won’t Load at All
Symptoms:
- Browser shows “This site can’t be reached” or timeouts.
- Redirects to a search page instead of login.
Fixes:
- Verify 10.0.0.1 is really your router IPIf the default gateway is something like 192.168.1.1 or 192.168.0.1, then your router simply doesn’t use 10.0.0.1—you need to log in using that IP instead.
- Check you’re on the right network
- Turn off VPNs and Proxies
- Try another browser or clear cache
2. 10.0.0.1 Asks for Login But Password Fails
Symptoms:
- Login page loads.
- Every username/password combo gives “incorrect password”.
Fixes:
- Try all common defaults
- Check the router label
- Consider ISP-branded details
- If nothing works → Factory reset
- The credentials have likely been changed and forgotten. Only a reset will return defaults.
3. 10.0.0.1 Works on One Device, Not Another
Symptoms:
- Laptop can log in, phone cannot, or vice versa.
Fixes:
- Ensure the problematic device is on the same WiFi (not mobile data).
- Turn off mobile data and retry from phone.
- Check that the problematic device isn’t on a guest network that blocks router access.
- Disable any per-device VPN or security apps temporarily.
4. Xfinity Gateway: 10.0.0.1 Blocked by xFi
Some newer Xfinity gateways restrict local admin access and push you through the Xfinity xFi app or Xfinity account instead.
If 10.0.0.1 redirects or won’t authenticate:
- Install and open the Xfinity app.
- Sign in with your Xfinity account.
- Go to your gateway settings inside the app to change WiFi name/password and basic options.
- For advanced options, check Admin Tool / Advanced Settings inside the app—Xfinity sometimes allows enabling local admin tool access again.
5. Last Resort: Factory Reset the Router
If you can’t log in at 10.0.0.1 because of a forgotten password and nothing else works:
- Locate the Reset Button
- Small pinhole on the back or bottom of the router.
- Press and Hold for 10–30 Seconds
- Wait for Full Reboot
- Give it a couple of minutes. WiFi networks will drop and reappear using factory defaults.
- Reconnect & Log In
Important (E‑E‑A‑T / safety): A factory reset wipes all custom settings—WiFi name, password, port forwarding rules, DNS overrides, etc. If you rely on special settings for work, remote access, cameras, or NAS, expect to reconfigure them afterward.
FAQs: 10.0.0.1 Admin Login
No. 10.0.0.0.1 is not a valid IP address. The correct local gateway address is 10.0.0.1—one zero after each dot, not two after the last dot.
Normally no. 10.0.0.1 is a private IP, only reachable from inside your local network. Remote access would require special port-forwarding or cloud-management features, which most ISPs now lock down for security.
Many Xfinity/Comcast gateways, some Technicolor and Cisco devices, and certain business-class routers use 10.0.0.1 as the default gateway. You can always confirm by checking your default gateway via ipconfig (Windows) or route -n get default (Mac).
