Review: Excellent RJ11 Cable - I write this review in response to the guy who complained that the cable is from 1999. The cable is "SFTP" shielded, and this is printed on the jacket. Those letters stand for "Screened Fully-Shielded Twisted Pair."This is an improvement over regular phone cables because of three things. 1. Pairs of conductors are twisted together to minimize crosstalk. This technology was invented by Alexander Graham Bell, so it much precedes the 1999 timestamp conferred by the other reviewer. it works by allowing both conductors of the pair to absorb the same amount of electromagnetic interference as one another from an adjacent source. 2. The pairs are each shielded with foil. This is another means to keep electromagnetic interference from altering the signal transmitted across the pairs, and it dates back to Michael Faraday. 3. All of the pairs (in this case two of them) are bundled and together wrapped in foil to further protect the integrity of the signals transmitted through them. None of this technology is groundbreaking, but the reason to use shielded cat 5e ethernet cable is simple: most phone cord doesn't go to such great lengths to protect the signal, while ethernet cable is designed with signal integrity in mind due to the greater throughput demanded by its applications. The connectors on this cable are very nice. Unlike most phone cords, they feature strain reliefs. The connectors are shielded, which is important for the foil shielding of the cables to work properly. At 7ft long, this cable may also be substantially shorter than the green DSL cable provided by your ISP. That is a good thing. If your green cable is bunched up and zip-tied, using a shorter cable ceteris paribus is an obvious way to reduce the voltage drop between your gateway and the ISP's DSLAM. This cable may not improve your connection if your internet is already working properly, but if you are having problems with your existing cable and/or you wish to spend a few bucks on a high-quality RJ11 cable for your DSL gateway, it is a solid choice. Don't worry about the year that cat 5e was introduced; cat 7 was introduced in 2002 but that doesn't mean 10GigE is obsolete. Focus instead on the problems you are having with your internet service and how to improve your connection by improving the weakest links in your setup. Review: Cable works great for us. - Our office has had high speed Internet for years, mostly DSL thru Bell South now ATT. We were informed by ATT that it is phasing out DSL in our area and replacing it with Uverse. We upgraded. After the upgrade we had a lot of problems with our ATT Uverse router/modem dropping the signal. We had no fewer than 7 ATT Uverse technicians out to work on the problem over a 2 week period. They did considerable work on the outside lines eliminating what they called "bridge taps" and that improved things a lot. But we were still getting dropped from time to time, about once a week and it seems we were not getting the full speed we were paying for. One of the techs noticed that the cable supplied by ATT with the router/modem (a Motorola NVG510) was not a shielded cable and that as installed in our office the Uverse cable from the jack in the wall to the router/modem was in what can only be described as a "spaghetti junction" of other cables feeding the phones, computers, printers and so on. To minimize interference from the other cables we bought this cable off desertcart and installed it to replace the unshielded cable that ATT supplied. We have gone over 90 days now and been dropped off the Internet by Uverse only 1 time, which is great (originally we were getting dropped 2 or 3 times per day, then 1 or 2 times per week, now after this cable and the other fixes mentioned only 1 time in over 90 days). We are also now getting almost the full Uverse speed we pay for (we pay for 12,000 kbps and are actually getting 11,997 kbps). While I cannot say this cable alone solved all our problems as many of them were located in the lines outside our building, I can say as we got the outside line problems fixed this shielded cable helped eliminate our remaining problems involving cross interference from our other cables and helped further reduce our drop rate and help us get the full Uverse speeds we paid for. Not a magic bullet, but it certainly helped. Very pleased. ## Features - RJ11 Data Transfer Cable - One (1) transparent blue 7 foot RJ11 DSL Modem Cable - Use - Connect any broadband DSL modem into a phone jack with this internet cable for faster internet speeds and data transmission than any regular phone cord - Durable - Snagless molded connector gives increased durability by reducing strain on the internet cable adapter - High Speed Data - Internet connection cable with foil double-shielding reduces interference, while the twisted-pair construction minimizes crosstalk for high speed, error-free DSL data transfer - Compatibility - Internet cable connector is compatible with all DSL modems from AT&T, CenturyLink, Xfinity and more, so you have an easy set up - Packaging - C2G cables are packaged in sturdy and reliable packaging in order to ensure a quality cable is delivered to your home ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000083JZ0 | | Best Sellers Rank | #38 in Modem Cables #110 in Computer Networking Modems | | Brand | C2G | | Brand Name | C2G | | Cable Type | RJ11 | | Color | Gray | | Compatible Devices | Modem | | Compatible Phone Models | Most RJ11 phone jacks | | Connectivity Technology | Ethernet | | Connector Gender | Male-to-Male | | Connector Type | RJ11 | | Customer Package Type | Flat Free Package | | Customer Reviews | 4.5 out of 5 stars 2,046 Reviews | | Ethernet Cable Category | Cat 5 | | Global Trade Identification Number | 00757120287216, 07571202872168 | | Included Components | RJ11 Cable | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Length | 7 Feet | | Item Shape | Round | | Item Weight | 0.15 Pounds | | Manufacturer | C2G | | Model | 28721 | | Model Name | 28721 | | Number of Items | 1 | | Number of Pins | 2 | | Other Special Features of the Product | High Speed | | Outer Material | Polyvinyl Chloride (PVC) | | Part Number | 28721 | | Recommended Uses For Product | Modem | | Special Feature | High Speed | | Specification Met | Meets General Ethernet Cable Specifications | | UPC | 014444694671 151903689332 757120287216 778889529355 163121392383 | | Unit Count | 1.0 Count | | Warranty Description | Lifetime | ## Product Details - **Brand:** C2G - **Cable Type:** RJ11 - **Compatible Devices:** Modem - **Connector Type:** RJ11 - **Special Feature:** High Speed ## Images ![C2G RJ11 Modem Cable For DSL Internet - Connects Phone Jack To Broadband DSL Modems For High Speed Data Transfer - 7ft Long Ethernet Network Cable With Double-Shielding To Reduce Interference - 28721 - Image 1](https://m.media-amazon.com/images/I/71DISWgeaqL.jpg) ![C2G RJ11 Modem Cable For DSL Internet - Connects Phone Jack To Broadband DSL Modems For High Speed Data Transfer - 7ft Long Ethernet Network Cable With Double-Shielding To Reduce Interference - 28721 - Image 2](https://m.media-amazon.com/images/I/71BixHuNLJL.jpg) ![C2G RJ11 Modem Cable For DSL Internet - Connects Phone Jack To Broadband DSL Modems For High Speed Data Transfer - 7ft Long Ethernet Network Cable With Double-Shielding To Reduce Interference - 28721 - Image 3](https://m.media-amazon.com/images/I/71ekyLVVcVL.jpg) ![C2G RJ11 Modem Cable For DSL Internet - Connects Phone Jack To Broadband DSL Modems For High Speed Data Transfer - 7ft Long Ethernet Network Cable With Double-Shielding To Reduce Interference - 28721 - Image 4](https://m.media-amazon.com/images/I/71+VUoOIGeL.jpg) ![C2G RJ11 Modem Cable For DSL Internet - Connects Phone Jack To Broadband DSL Modems For High Speed Data Transfer - 7ft Long Ethernet Network Cable With Double-Shielding To Reduce Interference - 28721 - Image 5](https://m.media-amazon.com/images/I/71t1lSg6pzL.jpg) ## Available Options This product comes in different **Color, Size, Style** options. ## Questions & Answers **Q: Will this work well for AT&T U-verse?** A: Works great on U-Verse. I saw a small but quantifiable boost in internet speeds over the cable they originally used during installation. **Q: Would work with and adsl modem router?** A: I have used a similar cable for my CenturyLink C1000A and C1900A routers. This cable would also be an upgrade for old internal phone wiring (un-shielded twisted pair). **Q: I ordered this rj11(6ft). I received rj12(7ft) both had the #28721. will this rj12 work?.** A: Physically they are the same connector, so if an RJ11 plug will fit into a socket, then an RJ12 could instead.Where they differ is the wiring. RJ11 has wires to 4 of the 6 pins, where as RJ12 uses all 6. Yes, I believe it will. **Q: Can I exchange it for a longer one?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent RJ11 Cable *by B***T on July 10, 2021* I write this review in response to the guy who complained that the cable is from 1999.

Seriously, I have been involved in tech for going on 20+ years, and one of the things that I learned early on was that if there is an issue with anything that is connecting or connected to anything else - and where a cable is involved at any point - *always* check the cables! It's often not obvious - or even visible at all - when a cable has an issue, and it can cause a slow connection, or an erratic connection, or even no connection at all! It's also the simplest and cheapest thing to check! Most recently I ordered this particular cable because I had upgraded to a newer, high-speed modem, and trust me, when your ISP ships you that new modem, they are *not* including good quality cables (unless they are a very unusual ISP). So I ordered this cable, and I can confirm that it's a great cable, and works very well! ## Frequently Bought Together - C2G RJ11 Modem Cable For DSL Internet - Connects Phone Jack To Broadband DSL Modems For High Speed Data Transfer - 7ft Long Ethernet Network Cable With Double-Shielding To Reduce Interference - 28721 - C4000BG CenturyLink Bonded Line Wi Fi DSL Router - NECABLES CAT5E RJ11 Data Cable DSL Cable 6ft Heavy Duty High-Speed DSL Modem Cable 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.be/products/1439143-c2g-rj11-modem-cable-for-dsl-internet-connects-phone-jack](https://www.desertcart.be/products/1439143-c2g-rj11-modem-cable-for-dsl-internet-connects-phone-jack) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-21*
