NOYAFA Network & Cable Testers Editorial Review
The AT226-C network cable tester is a versatile device that can measure distance to short and open as well as provide an IP address by reading from DHCP. However, it cannot speed test a cable on 100mbs or 1000mbs, and the manual does not recommend its use with POE. The battery lasts for 8-10 hours after being fully charged, and the device also comes with a card slot on the side for extended memory. The reception of the product has been mixed. Some customers have expressed that it is an affordable alternative to Fluke testers and have found it useful in identifying cable faults and distances, with the ping function being a bonus. Others have stated that it did not work right out of the box, and some have had issues with the device not holding a charge or randomly stopping working.
