Ethernet Lan Cable Tester

This cable tester seems to do the job well so far.

Not much to say about an ethernet cable, except that it works.

This is the simple but versatile device that I recommend as a router for all my friends and family, and will also use as an access point for them or small businesses where integrated solutions are too complex for a handful of users. Qualcomm Atheros chipset, with 350 Mbps WAN To LAN capability routing. Firmware has stabilized and now I am able to fully recommend (January 2021), albeit feature set is still lacking compared to AirRouter predecessor, but offers core abilities for baseline users. For the airCube, plug the ethernet from the modem into the WAN (eth0), then you may connect your computer via wireless or ethernet to the LAN ports (PoE In, 2, or 3), typing in https://192.168.1.1 in your web browser, with ubnt as username, and password printed on the label beneath. Most people are now aware and desiring to minimize wireless radiation, so I recommend them to turn off the 5 Ghz wireless, and configure the 2.4 Ghz for 20 MHz Channel Width, select channel 1, 6, or 11, while starting with 5 dBm output power (transmit power is logarithmic, so 5 dBm is 3mW, wile 20 dBm is 100 mW), and choose the SSID Name and Password. Look for a signal strength of -80 dBm or better (-55 to -60 dBm ideal) is recommended for stable links, and increase the output power until that range is achieved for desired places. Obviously, line of sight and height is appreciated for more effective communication. Increasing the Tx power on any wireless device will create a noise for other wireless devices. The rest you could choose to remain as default or configure more.

I use this with a 20gbps ethernet SFP+ backbone uplink from the UniFi SFP+ Aggregation Switch. My LAN has never been faster!

Very well made tester. Used to check usb cable.

This is a great cable tester for the money if you will mostly be testing internet cable.

The cable tester I have cannot test A(male) to A(male), so this helps a lot.

Short Ethernet cable that works.

Ethernet cable wet dream.

A Ethernet cable that works! And it was low cost.
