Finally got around to it and no joy. Hooked one end to the Internet router phone port (that works) then to RJ 45 to the other end of the house. Then into phone. No dial tone. Tried two different phones Ended up being a problem with the cat 6 cable. It only had four conductors! Who does that??? ### ⭐⭐⭐⭐⭐ Good price *by A***R on May 16, 2026* Product was as described and did the job. ### ⭐⭐⭐ Didn’t work for my purposes *by C***S on March 20, 2024* I really cannot say much about this other than I had to return because they didn’t work for what I wanted. I needed an adapter that would make a small cord that plugs into the back of a phone and make it into the larger size jack plug. I wasn’t sure if this would work but gave it a shot and it did not. ## Frequently Bought Together - Uvital Phone Jack to Ethernet Adapter, RJ11 to RJ45 Adapter, RJ45 Female to RJ11 Male for Landline Telephone, with RJ45 to RJ11 Cable (Black,2 Pack) - NECABLES 2Pack RJ45 to RJ11 Adapter Converter Cable 3ft RJ45 8P4C Male to RJ11 6P4C Male Gray - 3 Feet - Phone Jack to Ethernet Cable Adapter, RJ45 8P8C Female to RJ11 6P4C Male for Landline Telephone Service (2 Pack) --- ## 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.us/products/521397223-uvital-phone-jack-to-ethernet-adapter-rj11-to-rj45-adapter](https://www.desertcart.us/products/521397223-uvital-phone-jack-to-ethernet-adapter-rj11-to-rj45-adapter) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-20*
