WiFi Signal

4.2.2
30 October 2019

Monitor and troubleshoot the quality of your Wi-Fi connection.

Overview

WiFi Signal is a system menu bar application that provides easy access to your Wi-Fi connection details (name, channel, transmit rate, signal strength, noise, etc.), monitors the signal quality of your wireless network, and can find and recommend alternative channels for your network thus avoiding signal overlapping and channel conflicts that can result in connectivity issues and performance degradation.

Features
  • Simple, straightforward user interface
  • Accurate dBm to percentage conversion
  • Real-time signal strength and noise level graph
  • Signal quality ratings based on Signal-to-Noise Ratio (SNR) measurements
  • Automatic channel recommendations
  • Comprehensive app's help describes how to use the tool the most effective way

Note: Due to limitations of the Wi-Fi scanning framework, channel recommendations are based solely on the detection of other Wi-Fi signals, and do not consider external sources of interference or hidden networks (i.e., networks that do not broadcast their SSIDs).

Well, I've tested this out for an hour.
It's not something I need so I uninstalled it.

The only benefit I see is that it can display the info in the menu bar so you don't have to Option-click the Wi-Fi icon to see it.

I'm staying in a hotel right now and there are 4 different signals which use the same name but different BSSID's. Two use channel 4 and two use channel 8 (verified by WiFi Explorer). But WiFi Signal only shows one, and says "no better channels to recommend for this network." That's probably true since I am connected to the strongest one, but I'd still like the option to connect to one of the other signals.
Sometimes at this hotel my Mac has connected to one of the weaker signals and no matter how many times I turned Wi-Fi off/on it wouldn't connect to the strongest one.

There are 16 items you can choose to display. There's no text for most of the items, so you have to know what you're looking at. Right now after the signal name and BSSID # I have 2.4 n 4 20 -57 71 -80 33 22 195 217 23.
It won't display the device name for the hotel's router (WiFi Explorer does), but with everything else showing it's using five inches of menu space (of course no one needs to display all that).
There's no option to show the IP address.

I'd like to clarify a few things.

You can add any text you want as part of the display pattern. You're not limited to the items only. For example, you could do "Ch %C" to get "Ch 11" in the status bar.

There's an option to show the IP address in the popup window (but no in the status bar).

The app also offers notifications for when you join, disconnect or roam to a different network. Also for when the channel changes or the link quality degrades. It also gives you event logging, which is useful for when you're troubleshooting problems over time.

The app displays the device name if available, same as WiFi Explorer.

Finally, I agree that having the ability to connect to a specific SSID would be nice, but it could be more problematic than beneficial because the OS is still under control, so the fact that you connect to a specific SSID doesn't mean you will be able to keep it that way.

I use WiFi Explorer (https://www.adriangranados.com/apps/wifi-explorer). It costs a bit more but there is a trial version available. If you only need basic information then neither of these apps is for you. But WiFi Explorer tells me a lot more about my WiFi signal than Option-clicking on the WiFi icon in the menu bar does. As for how well WiFi Signal works, we won't know until someone is willing to risk buying it without trying it first and tells us about it. Since the last comment below was made more than two years ago, we may never know—not here, anyway. It is well rated at the App Store, if you want to check it out there.

PS: I just found out (at the App Store) that WiFi Signal and WiFi Explorer are from the same developer. WiFi Explorer, however, does not use the menubar. Other than that, there's no easy way to compare the two, except that Wifi Signal is less expensive and doesn't have a trial version.

So, for $0.99 it does what the FREE applications Signal Strength and WiFiSpy (among others) FREELY do for FREE?

I realize that $0.99 is not going to break the bank but how do you know it is better than the free apps that claim to do the same thing if you can't try it first.

Also, I clicked on the graphic you provided and even zoomed in to around 75%, but the resolution is too low to clearly see the icon or even read most of the text in the drop-down box (on a 20” OS 10.7.5 iMac)! I cannot determine what is written in the icon’s yellow area — is it WiFi connection strength in percentage (I hope so)? Is there a preference setting to change whatever’s written inside the icon to some other metric, or perhaps to include the noise level as well as signal strength? Can the icon be moved to any position I like along the menu bar, like the OS X Wi-Fi status icon can (while holding the Command button)? If its position can’t be changed, because I use a few other optional menubar items and most apps have so many of their own, then WiFi Signal's position at the left end would make it the first to be dropped/excluded/obscured/nuked, usually by the 'Help’ menu of whatever app is in use. Can your icon's color, font and font size be changed? If those things can be adjusted to my liking, and if you can make it available outside of the CrApp Store, I’d gladly pay 99₵ for it. BTW, thanks for spelling WiFi without a hyphen, it annoys me when developers spell it Wi-Fi.

same info you get if you hold 'Alt' (option) key and clickin WiFi icon in menubar and you see same data info about your signal, why you need for that install extra app?
