10.1.10.1 is a private router address, and cusadmin is a router username used on some business gateways, especially older Comcast Business devices. Type http://10.1.10.1 into a browser while connected to that router, then sign in with the correct admin details. Do not type it into Google. That only wastes time.
TLDR: Use 10.1.10.1 when your router uses that address as its local login page. Use cusadmin only if your router expects that username. For example, a small office with 18 devices may use 10.1.10.1 to change Wi Fi settings in under 3 minutes, if the password is correct. If it fails, your router may use 192.168.1.1, 10.0.0.1, or a custom gateway address instead.

What is 10.1.10.1?
10.1.10.1 is not a normal website. It is a private IP address. That means it works inside your home or office network only.
Your router may use it as a control panel address. Think of it as the front desk for your network. You visit it to change settings like:
- Wi Fi name
- Wi Fi password
- Firewall rules
- Port forwarding
- Guest network access
- Connected device lists
If you are not connected to that router, the page will not load. This is normal. The address is private. Your phone on mobile data cannot reach it.
What does cusadmin mean?
cusadmin is a username. It is not an IP address. It is not a password. It is simply the login name used by some router admin panels.
On some Comcast Business gateways, the username is often cusadmin. Older devices may use a default password like highspeed. Newer ones may use a password printed on the router label. Some businesses change it during setup.
Honestly, it feels like router makers enjoy hiding this stuff in tiny print under the device. Expect to spend 40 seconds turning the box around and squinting at the sticker.
How to log in using 10.1.10.1 and cusadmin
Try this simple path first.
- Connect to the router by Wi Fi or Ethernet.
- Open a browser.
- Type http://10.1.10.1 in the address bar.
- Press Enter.
- Enter cusadmin as the username, if your router uses it.
- Enter the router admin password.
- Save changes only if you know what they do.
Use the browser address bar. Not the search box. If you search for the IP, you may get random pages. That does not help.
10.1.10.1 vs common private IP addresses
Routers do not all use the same login address. That is the annoying part.
Here are common private router IP addresses:
- 192.168.1.1 — very common on home routers.
- 192.168.0.1 — common on cable routers.
- 10.0.0.1 — common on some Xfinity gateways.
- 10.1.10.1 — seen on some business networks and gateways.
- 172.16.0.1 to 172.31.255.254 — less common, but valid for private networks.
The key point is simple. These addresses are for local networks. They are not public internet addresses. Millions of routers can use the same private IPs because they sit behind separate networks.
Why does 10.1.10.1 not open?
If the page fails, do not panic. It usually means one of these boring things happened.
- You are not connected to the right network. Join the router Wi Fi first.
- The router uses another IP. Try 10.0.0.1 or 192.168.1.1.
- The address was changed. An admin may have customized it.
- HTTPS is required. Try https://10.1.10.1.
- Your VPN is causing trouble. Turn it off for a minute.
- The router is frozen. Restart it and wait two minutes.
It drives me a little nuts when a router takes 90 seconds to show a login page, then acts like nothing happened. Give it a moment. Then refresh.
How to find your real router IP
If 10.1.10.1 fails, find your gateway address. That is the router IP your device is using right now.
On Windows:
- Open Command Prompt.
- Type ipconfig.
- Look for Default Gateway.
On Mac:
- Open System Settings.
- Go to Wi Fi.
- Open network details.
- Look for Router.
On iPhone:
- Open Settings.
- Tap Wi Fi.
- Tap the info icon next to your network.
- Check Router.
On Android:
- Open Settings.
- Tap Network and Internet.
- Tap your Wi Fi network.
- Check gateway or router details.
Default login vs changed login
Default usernames and passwords are meant for first setup. They are not meant to stay forever.
If cusadmin does not work, try these checks:
- Look at the router label.
- Check setup papers from your internet provider.
- Ask the office admin or installer.
- Try the provider app, if your service uses one.
- Call your ISP support line.
A factory reset can restore defaults. But be careful. It can erase Wi Fi names, passwords, firewall rules, and business phone settings. For an office, that can ruin a normal Tuesday very fast.
What can you change after login?
Once inside the admin panel, you can usually manage key settings.
- Change the Wi Fi name. Use a name people can recognize.
- Change the Wi Fi password. Use at least 12 characters.
- Create guest Wi Fi. Keep visitors away from work devices.
- Check connected devices. Remove strange devices.
- Update firewall settings. Do this with care.
- Set port forwarding. Only open what you need.
Simple security tips
Router admin pages are powerful. Treat them like a safe key.
- Change the default admin password. Do this first.
- Use WPA2 or WPA3. Avoid old weak security modes.
- Turn off remote admin access unless you truly need it.
- Update firmware when updates are available.
- Do not share admin access with every employee.
- Keep guest Wi Fi separate from business devices.
Quick comparison
| Item | What it is | Use |
|---|---|---|
| 10.1.10.1 | Private IP address | Opens some router admin pages |
| cusadmin | Username | Signs in to some gateway panels |
| 192.168.1.1 | Private IP address | Common home router login |
| 10.0.0.1 | Private IP address | Common ISP gateway login |
Bottom line: 10.1.10.1 is the door. cusadmin may be the name on the badge. The password is the key. If one part is wrong, you stay outside.
