192.168.0.10 is the default gateway IP address used by Motorola SURFboard cable modems and certain cable modem/router combos. Use the 192.168.0.10 login page to access your modem's management interface, view signal levels, and configure network settings.
To access your modem's admin panel, click below:
Most devices using 192.168.0.10 come with these default username/password combinations:
| Username | Password | Common Brands |
|---|---|---|
| admin | motorola | Motorola SURFboard SB/SBG series |
| admin | password | Motorola/Arris cable modems |
| (empty) | admin | Older SURFboard models |
| admin | admin | Generic cable modem/router combos |
| admin | changeme | Arris SURFboard SBG6580 |
If none work, check the sticker on the bottom of your modem or factory reset your device to restore defaults.
http://192.168.0.10 in the address bar (not the search bar) and press Enter.http://192.168.100.1 instead — many SURFboard models use that IP for their management interface. See our find your router IP guide.
| What You Typed | Why It Fails | Correct Format |
|---|---|---|
| 192.168.0.lO | Letters "l" and "O" instead of 10 | 192.168.0.10 |
| 192.168.0.1 | Missing the trailing zero — different IP | 192.168.0.10 |
| 192.168.0.100 | Extra zero — that's a different device | 192.168.0.10 |
| 192.168.010 | Missing dot before 10 | 192.168.0.10 |
| 192.168.O.10 | Letter "O" instead of zero in third octet | 192.168.0.10 |
| 192.168.0.10. | Trailing dot after the address | 192.168.0.10 |

The Motorola SURFboard series is one of the best-known cable modem product lines in North America. Models like the SB6141, SB6183, SB8200, and the gateway combos (SBG6580, SBG6700, SBG7600) have been staples of home internet connectivity for over a decade. These devices frequently use 192.168.0.10 as their management IP when operating as cable modems, though some models alternatively use 192.168.100.1.
The management interface on a SURFboard modem at 192.168.0.10 is primarily diagnostic rather than configurational. For standalone cable modems (non-gateway models), the web interface shows DOCSIS channel information including downstream frequency, SNR, power levels, and upstream channel data. This information is invaluable when troubleshooting slow speeds or intermittent connectivity — your ISP's technical support team will often ask for these values. Downstream power should be between -7 dBmV and +7 dBmV, upstream between 38 dBmV and 48 dBmV, and SNR above 33 dB for optimal performance.
For SURFboard gateway models (modems with built-in routers), 192.168.0.10 provides full router configuration including WiFi settings, DHCP server, port forwarding, firewall rules, and parental controls. The default admin password on many SURFboard gateways is "motorola" (all lowercase), though newer Arris-branded models may use "password" or "changeme" as the default. After Arris acquired the SURFboard brand from Motorola, some firmware versions changed the default credentials, so check the label on your specific unit.
192.168.0.10 is a private IP address defined by RFC 1918. It falls within the Class C private range of 192.168.0.0 to 192.168.255.255. Within the 192.168.0.0/24 subnet, 192.168.0.10 is the tenth usable host address. Unlike the more common gateway addresses ending in .1 (like 192.168.0.1), the .10 suffix indicates this is typically a secondary device on the network rather than the primary gateway.
Cable modem manufacturers assign addresses like 192.168.0.10 to their devices to maintain a clear separation between the modem's management interface and the primary router. When a standalone cable modem is connected to a separate router, the router takes 192.168.0.1 as the gateway while the modem keeps 192.168.0.10 for its diagnostic interface. This dual-address setup allows network administrators and users to access both devices independently without IP address conflicts.
As a private address, 192.168.0.10 cannot be reached from the internet. It is only accessible from devices connected to the same local network segment. This means you must be physically connected to the modem — either via Ethernet cable or, on gateway models, via WiFi — to access the management interface. Remote management from outside the local network requires a VPN or other tunneling solution.
| IP Address | Common Brands | Network Class |
|---|---|---|
| 10.0.0.1 | Xfinity, Comcast, Arris | Class A |
| 192.168.0.1 | D-Link, Netgear, TP-Link | Class C |
| 192.168.1.1 | Linksys, Asus, Cisco | Class C |
| 192.168.0.10 | Motorola SURFboard, Arris | Class C |
| 192.168.1.254 | AT&T, BT Home Hub | Class C |
Pro Tip: After your first login, immediately change the default admin password to prevent unauthorized access. Also consider updating the firmware for security patches.
Key Takeaways
192.168.0.10 is the default management IP address for Motorola SURFboard cable modems and some modem/router gateway combos. It provides access to modem diagnostics, signal level information, and on gateway models, full router configuration.
You may need to connect via Ethernet directly to the modem. If you're connected through a separate router, the modem's management IP may not be accessible. Try 192.168.100.1 as an alternative. See our find your router IP guide.
For Motorola SURFboard devices, try admin/motorola. Other common defaults include admin/password and admin/changeme. Check the label on the bottom of your modem for model-specific credentials.
Hold the reset button on the back of the modem for 10-15 seconds to factory reset. Note that cable modems may need to be re-provisioned by your ISP after a reset, which can take a few minutes.
No. 192.168.0.1 is typically the primary router's gateway address, while 192.168.0.10 is a management address for secondary devices like cable modems. Both are on the same subnet but serve different devices.
Optimal downstream power is between -7 dBmV and +7 dBmV, upstream power between 38 dBmV and 48 dBmV, and SNR above 33 dB. Values outside these ranges may cause slow speeds or disconnections. Contact your ISP if levels are consistently poor.
This only applies to SURFboard gateway models (SBG series). Login to the admin panel, go to WiFi or Wireless settings, change the password, and save. Standalone modems don't have WiFi settings. See our WiFi name change guide.
