Arris SVG2482AC Xfinity Voice Modem Router | DOCSIS 3.0, Phone

The renewed Arris SURFboard SVG2482AC is a DOCSIS 3.0 modem router combo built specifically for Xfinity internet and Xfinity Voice. It is one of the few retail modems with built-in telephone lines, which makes it the go-to replacement for Comcast customers with internet and phone bundles who want to stop paying the monthly gateway rental fee. Dual-band AC1750 WiFi, download speeds up to 1 Gbps, and two phone ports cover the whole bundle in one device.

Key Takeaways

• Xfinity Voice support: two built-in telephone lines make this one of the only retail modems that works with Comcast internet and phone (triple-play) bundles.
• DOCSIS 3.0 with download speeds up to 1 Gbps, suited to Xfinity plans under 1 Gbps.
• Dual-band AC1750 WiFi for smooth streaming and gaming, managed from the SURFboard Manager app.
• Battery backup capable, keeping phone service available during power outages, and renewed with a 90-day full coverage warranty.

Built for Xfinity Voice

Most retail modems only handle internet, which forces Xfinity Voice customers to keep renting Comcast's gateway. The SVG2482AC is the exception: its two built-in telephone lines are certified for Xfinity Voice, so internet and home phone both run through a modem you own. If you have a Comcast double-play or triple-play bundle and you are tired of the equipment fee, this is the modem built for exactly that situation.

Is the SVG2482AC Compatible with My Internet Provider?

The SVG2482AC is designed for Comcast Xfinity and is primarily used with Xfinity service, including internet and voice packages. It works well on Xfinity plans under 1 Gbps. For setup help, see our Xfinity activation guide. Verify compatibility with your specific plan through Xfinity before purchasing.

The SVG2482AC is not the right choice for other providers. Its voice features are certified for Xfinity only, and it does not work with fiber (Verizon Fios, AT&T Fiber, Google Fiber), DSL, satellite, or 5G home internet.

Is DOCSIS 3.0 Still Enough in 2026?

For many Xfinity households, yes. DOCSIS 3.0 comfortably handles the plans most voice-bundle customers are on, and the SVG2482AC supports downloads up to 1 Gbps. Where it is not the right fit: gigabit-plus plans, or buyers who want headroom for future speed upgrades. If that is you, and you do not need phone support, a DOCSIS 3.1 modem is the better long-term buy, and our Best DOCSIS 3.1 Modems of 2026 roundup covers the options by speed tier. For Xfinity Voice customers, the SVG2482AC remains the practical retail choice.

WiFi and App Management

Dual-band WiFi delivers combined speeds up to 1750 Mbps across 2.4 GHz and 5 GHz, enough for 4K streaming, gaming, and video calls throughout a typical home. The free ARRIS SURFboard Manager app lets you manage your network from your phone: view connected devices, set internet access rules, and adjust WiFi settings without touching an admin page. The SVG2482AC was also the first retail WiFi modem built on RDK-B, the software platform cable providers use to roll out new services quickly.

Battery Backup for Phone Service

The SVG2482AC includes battery backup capability, so with a compatible backup battery installed, your Xfinity Voice line can stay available during a power outage for emergency calls. That is a meaningful safety feature for households that rely on their home phone. The backup battery is sold separately.

Save on Modem Rental Fees

Xfinity charges a monthly fee to rent its gateway, typically around $15 per month, and voice customers have historically had little choice but to pay it. At $180 a year, this renewed SVG2482AC pays for itself in about six months. Check your current bill to see exactly what you are paying for equipment. If your rented gateway is aging or dropping calls, our guide on how long modems last covers the warning signs.

No. The SVG2482AC is designed for Comcast Xfinity, and its voice features are certified for Xfinity only. Cox and Spectrum customers should choose a modem approved for their provider instead.

Is DOCSIS 3.0 still good enough?

For plans under 1 Gbps, yes. DOCSIS 3.0 handles mid-tier Xfinity plans well. If you are on a gigabit-plus plan or want future headroom and do not need phone support, a DOCSIS 3.1 modem is the better long-term choice.

How do I activate the SVG2482AC on Xfinity?

Connect the coaxial cable, power, and your devices, then activate through the Xfinity app or website, or by calling Xfinity. Voice customers may need a quick call to move phone service to the new modem. Our Xfinity activation guide walks through the full process.

What do the lights on the SVG2482AC mean?

Blinking lights during boot are normal. After activation, the power, online, and telephone lights should be solid. Persistent blinking usually points to a signal or provisioning issue, and our Arris modem lights guide explains each light and the fixes.
