I have had the modem for several months with no problems and would recommend it. When something happened to my Internet connection, I found that unplugging the modem adapter, waiting several seconds, and then replugging it returned operation to normal. You can look at the actual manual via the company's link (following); it includes the list of contents in the box.http://www.dlink.com/-/media/Consumer_Products/DSL/DSL%20520B/Manual/DSL-520B_Manual_US.pdf **Q: Is this modem compatible with verizon dsl wifi signal?** A: The people who have answered this question before suck. "I don't know, ask the manufacturer" is dumb to put in a public forum, and especially when all of the information is listed below. This modem should be compatible with Verizon's DSL service, but it does not have wireless. This will get 1 device connected via Ethernet, without another switch or router in the mix. (I would purchase a different device if you need WiFi) **Q: Does ot work with windstream dsl** A: I contacted Wendy @ Windstream and she said "It may be possible to use an existing Windstream modem or a modem/router that has worked on another DSL provider's network. Please note that Windstream technical support cannot provide configuration or troubleshooting assistance on non-Windstream equipment. To check existing modem compatibility, contact a customer service representative. " So the answer is it probably will but you will have to use D-Lin support if you need help configuring it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by E***E on May 24, 2013* ### ⭐⭐⭐⭐⭐ Review *by O***Y on April 17, 2019* ### ⭐⭐⭐⭐ Review *by M***R on December 16, 2018* ## Frequently Bought Together - D-Link ADSL2+ Ethernet Modem-(DSL-520B) - NECABLES DSL Filter Splitter for Phone Line and Modem 6 Inductors Version RJ11 6P2C 1 Male to 2 Females White - NECABLES CAT5E RJ11 Data Cable DSL Cable 6ft Heavy Duty High-Speed for DSL Modem UTP Compatible with ATT RJ11 6P4C Male to Male Green - 6 Feet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/1279921-d-link-adsl2-ethernet-modem-dsl-520b](https://www.desertcart.co.th/products/1279921-d-link-adsl2-ethernet-modem-dsl-520b) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-05-16*
