Netgear DGND4000 Overview
The Netgear DGND4000 N750 Wireless Dual Band Gigabit DSL Modem Router combines a built-in ADSL2+ modem with fast dual-band WiFi and premium sharing features in a single unit. Simultaneous 2.4GHz and 5GHz bands deliver combined wireless speeds up to 750 Mbps, enough for HD streaming, large file transfers, and online gaming across a busy household or small office.
Because the DSL modem, router, and WiFi are all in one box, the DGND4000 replaces the rental modem from your DSL provider and simplifies your setup. A Gigabit Ethernet WAN port even lets it keep serving as your WiFi router if you later move to cable or fiber service.

Will this work with my internet company?
The Netgear DGND4000 is primarily used with Frontier DSL service in most areas. The built-in modem supports ADSL, ADSL2, and ADSL2+ lines only; it does not connect to VDSL or fiber service through the DSL port, though the Gigabit Ethernet WAN lets it work as a router behind a fiber or cable modem.
Always contact your service provider's customer service before placing your order to confirm this model will work with your line type and service plan. Some service plan speeds may not be supported.
Skip the Monthly Rental Fee
Most DSL providers charge $10 to $15 per month for rented equipment, which can reach $180 per year. Since the DGND4000 replaces both the rental modem and a separate WiFi router, a professionally refurbished unit typically pays for itself within a few months.
Setup
- Install an ADSL microfilter on every phone or fax that shares the DSL line (the modem itself connects without a filter).
- Connect the included DSL/phone cable from your wall jack to the modem's DSL port.
- Plug in the power supply and wait for the lights to stabilize.
- Connect a computer or phone to the preset WiFi network on the label, or by Ethernet.
- Open routerlogin.net and let the NETGEAR genie wizard walk you through setup. Keep your provider account details handy in case PPPoE credentials are required.
Frequently Asked Questions
Is the Netgear DGND4000 compatible with Frontier?
Yes, the DGND4000 is primarily used on Frontier ADSL lines in most areas, typically on legacy accounts. Confirm with Frontier customer service before ordering, since line types and supported speeds vary by address.
Does the DGND4000 work with VDSL or fiber internet?
Not through the built-in modem, which is ADSL2+ only. However, the Gigabit Ethernet WAN port lets the DGND4000 serve as your dual-band WiFi router behind a fiber ONT or cable modem, so it stays useful if your service changes.
What speeds does the DGND4000 support?
The ADSL2+ modem supports line rates up to 24 Mbps downstream, with actual speeds set by your plan and line quality. On the wireless side, N750 WiFi delivers up to 300 Mbps on 2.4GHz and 450 Mbps on 5GHz.
Can I share a hard drive or printer with the DGND4000?
Yes. The two USB 2.0 ports support ReadySHARE storage and printer sharing, DLNA streaming to TVs and consoles, remote file access through ReadySHARE Cloud, and automatic Time Machine backups for Macs.
Do I need DSL microfilters?
Yes, on any phone equipment that shares the DSL line. Each telephone, fax, or answering machine on the line needs an inline microfilter to prevent interference; the modem's own connection does not use one.
Is a DSL modem router still worth buying in 2026?
Only if you have an active ADSL line, since providers are steadily retiring copper DSL in favor of fiber. For a working Frontier ADSL connection, the DGND4000 remains a capable budget all-in-one, and its Gigabit WAN keeps it useful afterward. Browse our Frontier compatible modems for other options.
