10.0.0.138 Admin Login
10.0.0.138 is a Class A private IPv4 address that serves as the default gateway for a select group of router brands and models. Confirmed manufacturers that use 10.0.0.138 as their factory-set default IP include Thomson (SpeedTouch Home), NetComm (3G9WB, 3G9WT), and 2Wire (2701HGV-W), as well as certain Huawei DSL gateway models (HG520i). Because it belongs to the 10.0.0.0/8 block — the largest private address space defined by RFC 1918 — 10.0.0.138 is also widely assigned as a DHCP client address on any network whose gateway is 10.0.0.1. Whether your device uses it as a gateway or as a dynamically assigned host address, understanding how to reach and manage 10.0.0.138 is essential for keeping your home or office network running smoothly. Other common addresses in the same subnet include 10.0.0.1, which is the most widely used gateway in the 10.0.0.x range and is the default for Xfinity/Comcast and Cisco gateways.

How to Access 10.0.0.138
To reach the admin panel at 10.0.0.138, follow these steps:
- Connect to your network. Plug an Ethernet cable from your computer directly into one of the router's LAN ports, or connect via Wi-Fi. A wired connection is strongly recommended — it prevents you from being dropped mid-session if you accidentally change a wireless setting.
- Open any web browser. Chrome, Firefox, Edge, and Safari all work. Do not use the address bar as a search box — make sure you type the IP directly.
- Type the address. Enter http://10.0.0.138 into the address bar and press Enter. If the page does not load, try
https://10.0.0.138(some newer firmware versions enforce HTTPS). - Enter your credentials. On Thomson SpeedTouch Home and NetComm 3G9WB/3G9WT devices, the factory default is typically username: admin / password: admin. On 2Wire 2701HGV-W models the default password field may be left blank or set to user. Always check the label on the bottom or back of your device for the exact defaults.
- Explore the dashboard. Once logged in you can change your Wi-Fi SSID and password, configure port forwarding, set up parental controls, update firmware, and reserve static IP addresses for specific devices.
Because 10.0.0.138 is a private IP address, it is only reachable from inside your local network — no one on the internet can access your router's admin panel through this address.
If You Can't Access 10.0.0.138
If typing http://10.0.0.138 into your browser returns an error or a blank page, work through the following checks:
- Verify your gateway address. On Windows, open Command Prompt (Start > cmd) and run
ipconfig /all. Look for the Default Gateway field. On macOS or Linux, runnetstat -nrorip route. If the gateway shown is not 10.0.0.138, that is the address you should be using instead — check our guide to find your router IP address. - Check your cable or Wi-Fi connection. A loose Ethernet cable or a dropped Wi-Fi session is the most common reason the admin page won't load. Reconnect and try again.
- Disable browser extensions. Ad blockers and privacy extensions can interfere with local IP pages. Try opening an incognito/private window, which disables most extensions by default.
- Clear your browser cache. Stale cached data can cause redirect loops. Press Ctrl + Shift + Delete (Windows) or Cmd + Shift + Delete (Mac) to clear it.
- Try a different browser or device. If one browser fails, another may succeed. Testing from a second device also rules out a local software conflict.
- Check if the IP was changed. A previous administrator may have changed the router's LAN IP away from 10.0.0.138. If you cannot determine the new address, a factory reset (see below) will restore it to the default.
Router Brands That Use 10.0.0.138 as Default Gateway
Unlike the more ubiquitous 192.168.1.1 or 192.168.0.1, the address 10.0.0.138 is associated with a specific set of hardware. Here is what you need to know about each confirmed brand:
Thomson — SpeedTouch Home
The Thomson SpeedTouch Home is a DSL modem/router combo that ships with 10.0.0.138 as its factory default gateway. Thomson (later rebranded as Technicolor) deployed these units widely through European ISPs. The admin interface is accessible at http://10.0.0.138 with the default credentials admin / admin. The SpeedTouch Home's web UI is straightforward: the home page shows connection status, and sub-menus let you configure DSL settings, NAT, firewall rules, and wireless parameters. One quirk to be aware of is that the SpeedTouch firmware may redirect you to a setup wizard on first login — complete it before attempting advanced configuration.
NetComm — 3G9WB & 3G9WT
NetComm's 3G9WB (3G Wi-Fi Router with Battery) and 3G9WT (3G Wi-Fi Travel Router) both use 10.0.0.138 as their default LAN gateway. These compact, battery-powered routers are designed for mobile broadband via a 3G SIM card. The default login for both models is admin / admin. Because these are travel routers, you are likely to connect to them via Wi-Fi rather than Ethernet — look for the default SSID printed on the device label. The admin panel lets you manage APN settings, data usage limits, and Wi-Fi security.
2Wire — 2701HGV-W
The 2Wire 2701HGV-W is an ADSL2+ gateway that has been documented using 10.0.0.138 as its default IP in certain firmware configurations. 2Wire gateways were commonly distributed by AT&T and other North American DSL providers. The default username on this model is user, with no password required out of the box. The 2Wire admin interface is known for its ISP-branded appearance and may restrict access to certain advanced settings depending on the firmware version your ISP pushed to the device.
Huawei — HG520i
The Huawei HG520i ADSL2+ router has also been confirmed to use 10.0.0.138 as its default gateway in some regional firmware builds. Default credentials are admin / admin. Huawei's admin panel on this model is clean and well-organized, with tabs for Basic, Advanced, Security, and Maintenance. If you are managing an HG520i, pay attention to the Maintenance > Device section for firmware update options.
Factory Reset Procedures for 10.0.0.138 Routers
If you have forgotten your admin password or the router is behaving unexpectedly, a factory reset will restore 10.0.0.138 as the default gateway and reset all credentials to their out-of-box defaults. Warning: a factory reset erases all custom settings including your Wi-Fi name, password, port forwarding rules, and any other configuration you have applied.
Thomson SpeedTouch Home — Factory Reset
- Locate the Reset button on the back or underside of the unit.
- With the router powered on, press and hold the Reset button using a straightened paperclip or pin for 15 seconds.
- Release the button. The router's LEDs will flash and the device will reboot.
- Alternatively, you can perform a power-cycle reset: unplug the power cord, press and hold the Reset button, then plug the power cord back in while continuing to hold the button. Release after 10–15 seconds.
- Once rebooted, navigate to http://10.0.0.138 and log in with admin / admin.
NetComm 3G9WB / 3G9WT — Factory Reset
- Ensure the router is powered on.
- Find the small Reset pinhole on the back of the device.
- Insert a pin or paperclip and hold for 10 seconds until the LEDs indicate a reboot cycle.
- After the router restarts, connect to its default Wi-Fi network (SSID on the label) and browse to http://10.0.0.138 with admin / admin.
2Wire 2701HGV-W — Factory Reset
- With the gateway powered on, press and hold the Reset button (located on the back panel) for 10 seconds.
- The power LED will turn red and then green once the reset is complete.
- Log in at http://10.0.0.138 using username user and leaving the password field blank.
Huawei HG520i — Factory Reset
- With the router powered on, press and hold the Reset button on the rear panel for 10 seconds.
- All LEDs will briefly turn off and then come back on as the device reboots.
- Once the router has fully restarted, access the admin panel at http://10.0.0.138 with admin / admin.
Changing Your Router Password at 10.0.0.138
Keeping the default admin / admin credentials on any router is a serious security risk. Anyone connected to your network — including guests on your Wi-Fi — could log in and change your settings. Here is how to update your password on a router accessed via 10.0.0.138:
- Log in to http://10.0.0.138 with your current credentials.
- Navigate to the Administration, Management, or Maintenance section — the exact label varies by brand. On Thomson SpeedTouch devices look for Toolbox > User Management. On NetComm 3G9WB/3G9WT look under Administration > Management.
- Find the Change Password or Admin Password field.
- Enter your new password twice to confirm. Choose a password that is at least 12 characters long and combines uppercase letters, lowercase letters, numbers, and symbols.
- Save the changes. You will be prompted to log in again with your new password.
Also consider changing your Wi-Fi password and SSID (network name) from the defaults at the same time. Default SSIDs often reveal the router model, making it easier for attackers to look up known vulnerabilities.
Router Username and Password List
| Brand | Model | Protocol | Username | Password |

What Is 10.0.0.138 as a Private IP Address?
10.0.0.138 is a Class A private IPv4 address, defined by RFC 1918 as part of the 10.0.0.0/8 block. This block spans from 10.0.0.0 to 10.255.255.255 and can accommodate over 16 million unique host addresses — making it the largest private address space available. Because it is private, 10.0.0.138 is not routable on the public internet. Packets sent to or from this address stay within your local network. When your router needs to communicate with the internet on behalf of your devices, it uses Network Address Translation (NAT) to swap the private address for your router's public IP before the packet leaves your home network.
Within the narrower 10.0.0.0/24 subnet — which covers 10.0.0.1 through 10.0.0.254 — the address 10.0.0.138 sits in the upper half of the range. On networks where 10.0.0.1 is the gateway, your router's DHCP server will typically hand out addresses starting from 10.0.0.2 upward. A device that joins the network after 137 other devices have already received addresses would be assigned 10.0.0.138 — which is why you may see this address appear as a client IP rather than a gateway IP on larger home or small-office networks.
Here is a practical illustration of how addresses are distributed on a typical 10.0.0.x network:
- 10.0.0.1 — Router/gateway (Xfinity, Comcast, Cisco, Apple AirPort)
- 10.0.0.2 – 10.0.0.137 — DHCP-assigned client devices (laptops, phones, tablets, smart TVs)
- 10.0.0.138 — Either the router gateway (Thomson, NetComm, 2Wire, Huawei) or a DHCP-assigned client address
- 10.0.0.139 – 10.0.0.254 — Additional DHCP-assigned or statically configured devices
- 10.0.0.255 — Broadcast address (not assignable to any device)
Because only one device on a network can hold a given IP address at any time, you must ensure that 10.0.0.138 is not assigned to two devices simultaneously. If your router uses 10.0.0.138 as its gateway, configure your DHCP pool to start at 10.0.0.139 or higher to prevent conflicts.
10.0.0.138 and the Class A Address Space
IP addresses are divided into classes based on their leading bits and the size of the network they represent. 10.0.0.138 is a Class A address — specifically, it falls within the private Class A block reserved by IANA for internal use. Class A networks use the first octet to identify the network and the remaining three octets for host addresses, which is why the 10.x.x.x range can support such an enormous number of devices.
In practice, most home routers use the much smaller 192.168.x.x (Class C private) range because a typical household only needs a few dozen addresses. The 10.x.x.x range is more commonly seen in:
- Enterprise and campus networks — where thousands of devices need unique private addresses.
- VPN tunnels — many VPN services assign clients addresses in the 10.0.0.x range.
- ISP-provided gateways — some cable and DSL providers (including certain Comcast/Xfinity configurations) use 10.x.x.x addressing for their customer-premises equipment.
- Virtualization platforms — hypervisors like VMware and VirtualBox often default to 10.0.0.x for virtual machine networks.
- Mobile broadband routers — devices like the NetComm 3G9WB use 10.0.0.138 partly because the 10.x.x.x space is less likely to conflict with the cellular carrier's own addressing scheme.
Understanding that 10.0.0.138 belongs to Class A helps you make smarter subnetting decisions. If you are setting up a network from scratch and your gateway is 10.0.0.138, you can choose a subnet mask of 255.255.255.0 (/24) to limit the network to 254 hosts, or use a wider mask like 255.255.0.0 (/16) if you need to accommodate thousands of devices.
Related IP Addresses in the 10.0.0.x Subnet
If 10.0.0.138 is not the right address for your setup, or if you are exploring other devices on the same network, the following addresses in the 10.0.0.0/24 subnet are worth knowing about:
- 10.0.0.1 — The most widely used gateway in the 10.0.0.x subnet. Xfinity (Comcast), Cisco, and Apple AirPort devices commonly default to this address. If you are on a Comcast-provided gateway and 10.0.0.138 does not respond, try 10.0.0.1 instead.
- 10.0.0.2 — Often the first address assigned by DHCP after the gateway. Also used as a secondary DNS or secondary gateway in some configurations.
- 10.0.0.100 — A common static address assigned to network printers, NAS devices, or IP cameras on 10.0.0.x networks.
- 10.0.0.254 — The last usable host address in the 10.0.0.0/24 subnet. Some administrators assign this to the gateway to keep it clearly separated from client addresses.
For networks outside the 10.0.0.x range, the most commonly encountered private gateways are 192.168.1.1, 192.168.0.1, 192.168.1.254, and 192.168.100.1.
Frequently Asked Questions About 10.0.0.138
What devices use 10.0.0.138 as their default gateway?
The confirmed router models that ship with 10.0.0.138 as their factory default gateway are the Thomson SpeedTouch Home, NetComm 3G9WB, NetComm 3G9WT, 2Wire 2701HGV-W, and Huawei HG520i. On any other network where the gateway is 10.0.0.1, the address 10.0.0.138 may simply be a DHCP-assigned client address rather than a gateway.
Is 10.0.0.138 safe to access?
Yes — 10.0.0.138 is a private IP address and is only reachable from within your local network. No one on the public internet can connect to it directly. That said, you should still protect your router's admin panel with a strong, unique password to prevent unauthorized access from devices already on your network.
Why does my browser show a security warning when I visit 10.0.0.138?
Some routers at 10.0.0.138 use a self-signed SSL certificate for their HTTPS admin interface. Your browser flags this because the certificate was not issued by a trusted public authority — but it does not mean the connection is compromised. You can safely click Advanced > Proceed (Chrome) or Accept the Risk and Continue (Firefox) to reach the login page.
Can I change my router's IP from 10.0.0.138 to something else?
Yes. Log in to the admin panel at http://10.0.0.138, navigate to the LAN or Network settings section, and update the LAN IP address field. After saving, your router will reboot and you will need to use the new address to access the admin panel. Only change this if you have a specific reason — such as resolving an IP conflict with a VPN or another network device.
What is the default username and password for 10.0.0.138?
The most common default credentials for routers using 10.0.0.138 are admin / admin (Thomson SpeedTouch Home, NetComm 3G9WB, NetComm 3G9WT, Huawei HG520i). The 2Wire 2701HGV-W uses user as the username with a blank password. Always check the sticker on the bottom or back of your specific device, as ISPs sometimes customize the default credentials before shipping the hardware.
What should I do if I'm locked out of 10.0.0.138?
If you have forgotten your admin password and cannot log in to 10.0.0.138, your only option is a factory reset. Locate the Reset pinhole on your Thomson SpeedTouch Home, NetComm 3G9WB/3G9WT, 2Wire 2701HGV-W, or Huawei HG520i, and hold it for 10–15 seconds with a pin or paperclip while the device is powered on. This restores the default credentials and the 10.0.0.138 gateway address. See the factory reset section above for model-specific instructions.
