3. At the login screen, enter admin for the username and password for the password.
4. Click Login. You will see the Gateway At a Glance page.

If the default login does not work, someone may have changed the credentials previously. Press and hold the Reset button on the back of the modem with a paperclip for 10-15 seconds to restore factory defaults. Note that this will erase all custom settings.

How to Change the Wi-Fi Name and Password on the ARRIS SVG2482AC

Your modem comes with a default Wi-Fi name and password printed on its label. For better security, you should change both after activation.

1. Log into the admin panel at http://10.0.0.1 using the steps above.
2. Click Gateway in the top menu, then select Connection, then Wi-Fi.
3. You will see settings for both the 2.4 GHz and 5 GHz wireless networks.
4. To change the network name, update the text in the Network Name (SSID) field.
5. To change the password, update the text in the Network Password field. Use at least 8 characters with a mix of letters, numbers, and symbols.
6. Make sure Security Mode is set to WPA2-PSK (AES) for the best protection.
7. Click Save Settings.

After saving, all currently connected wireless devices will be disconnected. Reconnect each device using the new network name and password.

How to Set Up Bridge Mode on the ARRIS SVG2482AC

Bridge mode disables the modem's built-in router and Wi-Fi, turning it into a modem-only device. This is useful if you want to use a separate, more advanced router. It prevents "double NAT" issues that can cause problems with online gaming, VPN connections, and port forwarding.

1. Connect a computer to the modem using an Ethernet cable. Do not use Wi-Fi for this process because Wi-Fi will be disabled when bridge mode is activated.
2. Log into the admin panel at http://10.0.0.1.
3. Click Gateway in the top menu, then select Connection, then Local IP Network.
4. Look for the Bridge Mode or Gateway Mode setting.
5. Change the setting from Router (or NAT) to Bridge.
6. Click Save Settings. The modem will restart.
7. After the restart, connect your separate router to one of the modem's Ethernet ports using an Ethernet cable.

Important: While in bridge mode, you can no longer access the modem's admin panel over Wi-Fi. You will need to connect directly via Ethernet to manage modem settings. To return to router mode, connect via Ethernet, log in at 10.0.0.1, and change the setting back to Router.

How to Set Up Parental Controls on the ARRIS SVG2482AC

The SVG2482AC includes built-in parental controls that let you block specific websites, restrict internet access by time of day, and filter content by device.

Block Specific Websites

1. Log into the admin panel at http://10.0.0.1.
2. Click Parental Control in the top menu.
3. Select Managed Sites.
4. Click the Enable Managed Sites button to turn on website blocking.
5. Enter the URL of a website you want to block (for example, www.example.com) and click Add.
6. Repeat for additional websites as needed.

Block by Keyword

You can also block access to any website that contains a specific keyword in its URL. In the Parental Control menu, enter keywords you want to block and click Add.

Block Specific Devices

1. In the Parental Control menu, select Managed Devices.
2. Click Enable Managed Devices.
3. Add the MAC address of any device you want to block or restrict. You can find connected device MAC addresses on the Connected Devices page in the admin panel.

Set Time-Based Access Restrictions

1. In the Parental Control menu, look for the time restriction or scheduling option.
2. Set the allowed days and hours for internet access.
3. Apply the time rule to the specific device or devices you want to restrict.
4. Click Save Settings.

Note: The built-in parental controls on the SVG2482AC are relatively basic compared to what most standalone routers or third-party software offer. If you need more granular filtering, content categories, or app-level controls, consider putting the modem in bridge mode and pairing it with a router from ASUS, Netgear, or TP-Link, which typically offer more robust parental control features.

How to Factory Reset the ARRIS SVG2482AC

A factory reset restores the SVG2482AC to its original out-of-the-box settings. This erases all custom configurations, including your Wi-Fi name and password, parental controls, bridge mode settings, firewall rules, and any admin login changes. A factory reset is useful when you cannot log into the admin panel, need to clear a misconfiguration, or are preparing the modem for a new owner.

Important: Before resetting, disconnect the coaxial cable from the back of the modem. The SVG2482AC is known to not fully reset while the coaxial cable is connected because the ISP's provisioning signal can interfere with the process. If you skip this step, the modem may appear to reset but retain old configuration data or fail to return to true factory defaults.

1. Unplug the coaxial cable from the Cable In / RF In port on the back of the modem.
2. Leave the power cable plugged in so the modem stays powered on.
3. Locate the small recessed Reset button on the back of the modem.
4. Insert a paperclip or similar pointed object into the reset hole and press and hold the button for 15 seconds.
5. Release the button. The modem will restart on its own. Wait 2-3 minutes for the reboot to complete -- you will see the front panel LEDs cycle and then settle.
6. Once the modem has fully restarted, reconnect the coaxial cable.
7. Wait for the Power, DS, US, and Online LEDs to turn solid, which indicates the modem has re-established its connection with your ISP.

After the reset, the modem will use the default Wi-Fi name (SSID) and password printed on the label on the bottom or back of the unit. The admin panel login will revert to the default username admin and password password at http://10.0.0.1. If you had previously activated voice service or custom ISP settings, you may need to contact your provider to re-provision the modem.

Troubleshooting Common Setup Issues

Modem Will Not Activate

• Double-check that the coaxial cable is securely connected at both the wall outlet and the modem.
• Confirm you are providing the correct CM MAC address (not the Wi-Fi MAC or serial number) to your provider.
• Power cycle the modem by unplugging it for 30 seconds and plugging it back in.
• If activating with Xfinity, try calling 1-855-652-3446 for manual activation.

Cannot Log Into the Admin Panel

• Make sure you are connected to the modem's network (wired or wireless), not a different router.
• Try both 10.0.0.1 and 192.168.0.1 in your browser.
• Clear your browser cache or try a different browser.
• If the default credentials do not work, perform a factory reset by pressing and holding the Reset button on the back for 15 seconds.

Wi-Fi Network Not Showing Up

• Verify the wireless LEDs on the front of the modem are lit. If not, Wi-Fi may be disabled.
• Log into the admin panel and make sure both the 2.4 GHz and 5 GHz wireless networks are set to Enable.
• Perform a factory reset and reconnect using the default SSID and password from the modem's label.

Slow Internet Speeds

• Run a speed test at speedtest.net using a wired Ethernet connection to rule out Wi-Fi issues.
• Make sure no one on the network is running bandwidth-heavy tasks like large downloads or 4K streaming.
• Try changing the Wi-Fi channel in the admin panel (channels 1, 6, or 11 are recommended for 2.4 GHz).
• Contact your ISP to confirm your plan speed and check for outages.

Frequently Asked Questions

Does the ARRIS SVG2482AC work with Spectrum?

Yes, the SVG2482AC works with Spectrum for internet service. However, the built-in telephone ports are only supported with Comcast Xfinity Voice. If you have Spectrum and need a phone line, you will need a separate telephony adapter.

What is the default login for the ARRIS SVG2482AC?

The default IP address is 10.0.0.1. The default username is "admin" and the default password is "password" (all lowercase). If those credentials do not work, try the IP address 192.168.0.1. If you still cannot log in, perform a factory reset by holding the Reset button on the back of the modem for 15 seconds.

Can I use the SVG2482AC with AT&T or Verizon Fios?

No. The SVG2482AC is a DOCSIS 3.0 cable modem and is only compatible with cable internet providers. It does not work with fiber, DSL, or satellite services, including AT&T, Verizon Fios, CenturyLink, Frontier, or Google Fiber.

How do I reset the ARRIS SVG2482AC to factory settings?

First, disconnect the coaxial cable from the back of the modem -- the SVG2482AC may not fully reset while the coaxial line is connected. Then locate the small recessed Reset button on the back of the modem, insert a paperclip or similar pointed object, and press and hold the button for 15 seconds. Release the button and wait for the modem to restart. Once rebooted, reconnect the coaxial cable and wait for the Online LED to turn solid. This erases all custom settings, including your Wi-Fi name, password, parental controls, and firewall configuration. You will need to reconfigure the modem after resetting.

What is bridge mode and when should I use it?

Bridge mode turns off the SVG2482AC's built-in router and Wi-Fi functions so it operates as a modem only. Use bridge mode if you have a separate router that you prefer for Wi-Fi, or if you are experiencing double NAT issues that affect gaming, VPNs, or port forwarding. You can enable bridge mode in the admin panel under Gateway, then Connection, then Local IP Network.

Why is my SVG2482AC Wi-Fi so slow?

The SVG2482AC uses Wi-Fi 5 (802.11ac) technology, which is adequate for most households but may not deliver peak speeds in larger homes or with many connected devices. Try moving the modem to a central location, switching to the 5 GHz band for faster speeds on nearby devices, and changing the wireless channel to reduce interference. If performance remains poor, consider bridge mode with a more powerful standalone router or mesh system.

Does the ARRIS SVG2482AC have a known chipset issue?

Yes, the SVG2482AC uses an Intel Puma 6 chipset, which has a documented defect that can cause intermittent latency spikes and connection instability in some units. Not all modems are affected, but if you notice frequent lag spikes or inconsistent ping times -- especially during gaming or video calls -- this chipset issue may be the cause. A firmware update from your ISP can help reduce the impact, but it does not fully eliminate the problem in all cases.
