Port Scanning

Port Scanning is one of the features that comes with the Fing app and doesn't require the Fingbox. I ran a quick test on this feature, selecting my router as a target for a port scan. As you can see in the below image, the Fing app identified that ports 53 (DNS), 80 (HTTP), and 443 (HTTPS) are open on my router.

Wake on LAN

Wake on LAN (WoL) is an interesting tool for sending a special packet called a "magic packet" over a network to remotely turn a device on. More details on WoL can be found in this article. The Fing app will send a magic packet to devices on your network. If those devices are equipped and enabled for WoL, Fing will remotely turn them on. Unfortunately, I have no devices that support WoL, so I wasn't able to verify this feature.

Bandwidth Analysis

The Bandwidth Analysis and all the other features I'll describe going forward require Fingbox. Bandwidth Analysis allows you to examine multiple devices on your network and see which ones are consuming the most bandwidth at any given time.

In the screenshot, I've selected my laptop (T460-Laptop-wired) and iPhone. I ran a speedtest on the laptop to make sure it was consuming bandwidth while I left the iPhone idle. As you can see, the Fingbox detected my laptop is consuming 65.7 Mbps while my iPhone is consuming 0.0 Mbps.

Internet Speed Testing

Fingbox measures your internet speed and uses the results to calculate the devices consuming the highest percentages of your bandwidth. I first ran a speedtest using the Fing app, which reported my internet speed at 25.6 Mbps down and 6.0 Mbps up. This was a lower than expected result, as my internet connection is supposed to be 50 Mbps down and 5 Mbps up.

I then ran a speed test from a wired PC on the same network using speedtest.net. This test from the wired PC returned a result of 70.88 Mbps down and 5.89 Mbps up. This method didn't measure my downlink throughput accurately, either.

I thought the discrepancy might be that the Fingbox speed test was running from my smart phone over Wi-Fi, but that wasn't the case. I disconnected Fingbox and the Fing speed test wouldn't run, which tells me the Fingbox appears to be running the speed test via its wired Ethernet connection. It's possible the discrepancy was due to the servers used for each test (Fing has partnered with M-Lab for speed testing). The Fing speed test says it was testing to a location in Atlanta, GA, whereas the speed test I ran on my wired PC was connecting to a server not far from my location in Charlotte, NC.

I ran the Fing test multiple times and later got a result of 64 Mbps down and 5.8 Mbps, which is closer to what I expected. A nice feature is the Fing app tracks your speed results and displays them in the internet Speed History menu, shown below.

Wi-Fi Performance

A useful Fingbox tool is the Wi-Fi performance tool that enables measurement of your local Wi-Fi speeds. The Fing app on your smartphone runs a speed test between it and Fingbox; no internet servers are used. This tool provides a handy means of measuring your Wi-Fi performance without inaccuracies introduced by using internet-based services.

Test results are averaged and displayed in real time on the screen shown below, so you can move around and see how speed changes. I used the tool in various locations of my house to discover where my Wi-Fi network was strongest and weakest.

Wi-Fi Speed Test

The history view shows past Wi-Fi speed test results. Note the Streaming Quality indication provided as part of the Wi-Fi Performance results. The 169.5 Mbps result shown above is deemed good enough for 4K streaming (25 Mbps). The SD and HD buttons will light up for measured speed of 3 Mbps and 5 Mbps and higher, respectively.
