Best Network & Cable Testers of 2025

"I just received this tool and used it right away for troubleshooting my complex home network. I wish I had this 10 years ago! It's perfect for finding bad cables and identifying the cables coming into a hub. The different ID terminators make mapping effortless. In my case, I discovered a port failure in a switch, not wiring issues. I would highly recommend this tester."

"If you're debating between this model and a cheaper one, I strongly suggest going with this one. I had a Klein tester that worked fine, but the backlit display and added features of this one really make my job easier. The built-in toner is fantastic. I appreciate its reliability, especially since I tend to misplace tools!"

"This product works like a charm! It catches every mistake I make—though I like to think I rarely make any! Some features were tricky at first, but once I figured them out, it became much smoother. I love being able to test multiple cables at once, turning a dreaded chore into a manageable task. It's definitely a time-saver for anyone needing efficient cable testing!"

“I use the LIQ for training, and it’s my favorite Cat cable tester for 5, 5e, 6, and 6A. The single pushbutton test might mislead some, but I found that I could customize all key test parameters easily. It’s light, charges quickly, and includes a remote and Cat 6A test cable.”

“After purchasing this device, it paid for itself on the second job by saving us time locating faults. If you're hesitating, I was too, but this is truly worth every cent.”

“I’ve worked with older buildings and never knew what to expect behind the walls. This tool has been a time-saver, allowing me to tone out connected cables and determine the actual cable types. The LinkWare PC software is also great for compiling results after jobs.”

"I find the Fluke Networks LIQ-KIT LinkIQ Cable + Network Tester Kit to be an excellent tool for network diagnostics. Its user-friendly design and accurate results make it perfect for both cable quality and network performance testing. The solid build quality and included accessories add to its versatility. I highly recommend it for anyone seeking a dependable tester."

"This device truly meets my needs. It checks switch POE power, cable length, and cable speed, although it doesn't certify the work. It's straightforward and does exactly what I expect."

"I've saved so much time with this tool! It allows me to track CAT5 cables in seconds. We now test all cables to a 10 GIG load, which has drastically reduced service calls related to cabling issues. Although it's expensive, it's worth every penny for the time savings it provides."

"I've relied on the MicroScanner2 since 2011. It's a reliable and accurate tool for measuring and troubleshooting thousands of cables. The toner generator is a great help in quickly identifying problems. I've purchased it four times and can confidently give it a 5/5 rating!"

"I initially hesitated due to some reviews claiming it wouldn't indicate Ethernet speed, but I found that it does show speed, ID, and pairs perfectly. My only suggestion is to use text alongside the icons for clarity. I don't regret spending my money on this Fluke product!"

"Despite being pricey, this tool has saved me more than it cost. It effectively identifies problems in LAN connections, even pinpointing which end the issue is on. It's an essential tool for anyone dealing with networking."

"This tool has been a game changer for my small access control and data drop installation business. While it doesn't match the capabilities of the DSX-5000 or DSX-8000, it certainly gives me a similar feel. I genuinely appreciate being able to present my clients with professional test results. I would definitely recommend this tester!"

"I take this tester to every job because it’s a Swiss army knife for network troubleshooting. It enables me to swiftly confirm or eliminate cabling issues, which I used to hesitate on due to costs. Now, I can confidently ensure that installations are up to spec, even after the datacom team thinks a job is complete."

"This device is fantastic for validating ethernet/IP and checking cable performance from 10mb/s to 10gb/s. It even performs ping tests to verify connectivity and switch diagnostics, making my job so much easier."

"I was initially skeptical, but I’m pleased to say it works exactly as expected. It may lack fancy features, but if you need to confirm connectivity on all wires, this device is definitely worth the price. I used it to verify a cable run from my attic to my basement, and it showed that everything was good. Speed tests on my laptop confirmed the expected speeds."

"I've had issues with cables pulling out due to broken clips. Rather than replacing five cables, I bought this tester along with a Klein Pass-Thru crimper and ends, and I was able to repair all my cables successfully. I’m now a happy DIY cable fixer!"

"This item is very simple to use and works well. However, I found the instructions to be a bit unclear."

"I needed a small network meter for testing data runs. Fluke is my go-to brand for networking meters. This one did everything I required and never gave me a wrong answer for cable issues."

"I initially bought this by mistake, thinking it would test cable throughput. It only reports advertised port speed from the switch. I gave it 3 stars because, while it's nice, it's overpriced for its functionality. I returned it unused, and the RMA process was fantastic through Amazon."

"This product is invaluable for troubleshooting a modern network. As the only IT person at my non-profit, it will definitely pay for itself by eliminating guesswork and avoiding expensive service calls to fix wiring issues."

"As a former cable man, I used three different Tone & Probe kits, from cheap ones to the Fluke Filtered T&P. For DIYers, cheaper options suffice, but if it's your profession, invest in a Fluke. It simply works well, especially in active networks where signal grounding issues can occur. I now own the Fluke and love its reliability. It's even great for bundled cables!"

"During a home renovation, I needed to trace circuits behind drywall. This tool was essential! The tone is strong enough to locate wires, but I did notice signal splash when multiple wires were in the same box. With patience, I sorted through the confusion and found each line. It works through drywall but requires some thought."

"As a master electrician for over 20 years, I’ve used this tone generator extensively. It’s a time-saver when locating wires in control panels. I've even given a few away to upcoming electricians, and they also love it. I highly recommend this product for anyone working with electricity, AC or DC. Can't afford to give more away!"

"I purchase a few of these annually for our elevator mechanics and fire alarm electricians. Dependable and always works well. I think the tone/pulse option is just there to annoy me."

"Having used Fluke products for years in the Fire & Life Safety industry, I can confidently say they are the leader in testing equipment. This tester is reliable, easy to use, and durable. I've had mine for over 5 years and it's fantastic."

"I recently replaced my old Harris T22A and opted for this one instead since I didn't want to spend $300. It gets the job done, and it’s straightforward to use if you're familiar with a butt set. Instructions are easy to follow, making it a must-have for testing POTS lines."

"I've been using this network cable tester extensively, and I'm thoroughly impressed with its capabilities and affordability. This versatile tool has made my network installations and troubleshooting tasks much easier. It features an optical power meter and VFL, making it invaluable for both fiber and Ethernet cable testing. The build quality is solid, providing the durability needed for regular field use."

"I feel like I got good value for what I paid. All the features seem to work fine, and I mostly use the unit to troubleshoot homemade cable terminations in my house. It has solved several problems for me, although the instruction manual is pretty much worthless. I found it easier to just jump in and start testing."
