I was using this to debug a Netgear wireless extender issue.
Acrylic Wi-Fi Analyzer
https://www.acrylicwifi.com/en/wifi-analyzer/ https://www.acrylicwifi.com/en/downloads/

But it's only a 5-day free evaluation.
Running a few searches I found these might do almost as well.

Any others you might suggest for debugging Wi-Fi router issues?

I use Nirsoft Wireless Network Watcher. So I can see who or what is on
my wifi.
What are you trying to debug? You can usually log into your Wireless
router using telnet and read the logs. Have you tried that?

'netsh wlan show profiles' lists the WiFi profiles saved on your computer.

'netsh wlan show networks' displays the WiFi networks currently visible.

'netsh wlan show wlanreport' generates a detailed HTML report of your WiFi activity over the last three days, which can be very helpful in diagnosing connection issues. This report includes information about SSIDs you've connected to, connection attempts, errors, etcetera.

'netsh wlan show interfaces' shows details about your WiFi adapter.

'arp -a' shows you a table that maps IP addresses to their physical MAC addresses on your local network.

'netsh wlan show networks mode=bssid' gives you a more granular view of the Wi-Fi environment by listing the details of each individual access point (identified by its BSSID) broadcasting a Wi-Fi network. '

'nmap -T4 -A -v 192.168.0.1/24' scans all IP addresses in the range of 192.168.0.1 to 192.168.0.254 on your local network for live targets. https://nmap.org/zenmap/

'lswifi' displays the Wi-Fi characteristics of your wireless network. https://github.com/joshschmelzle/lswifi

Like the shadowy man said, the Nirsoft suite has a free information viewer,
a history viewer, and a network watcher on the Windows platform.

Some others which have been suggested on a.c.f in the past are below.

NetSpot: Offers both a free version and paid versions. The free version
allows you to perform basic site surveys and visualize your WiFi network. https://www.netspotapp.com/

inSSIDer: A well-regarded tool, often used by professionals, for scanning
and analyzing WiFi networks. While it might be more geared towards business use, it's generally user-friendly. There might be older free versions available, but current versions are typically paid. https://www.techspot.com/downloads/5936-inssider.html

WiFi Analyzer (Microsoft Store app): A free and straightforward app
available on the Microsoft Store that visualizes your WiFi network and
helps identify the best channels. It's good for basic home use. https://apps.microsoft.com/detail/9nblggh33n0n?hl=en-US&amp;gl=US

Vistumbler: A free and open-source WiFi scanner that provides detailed information about access points.

You can usually find a free version if InSSIDer for Windows at the MetaGeek site or at the TechSpot site, but both require a MetaGeek account.

The last Windows version that didn't require you to sign up is the "Legacy Version 3.1.2.1" https://www.techspot.com/downloads/5936-inssider.html https://files02.tchspt.com/down/inSSIDer-installer.msi

If you can't find a free wear version of InSSIDer, try Angry IP Scanner https://angryip.org/download/
https://github.com/angryip/ipscan/releases

IP Range: 192.168.0.1 to 192.168.0.254
Hostname: dave IP: 192.168.0.0/24 or 255.255.255.0 (either way works fine)

Are you sure it's a 5 day evaluation?
I only see a limit of 5 devices in the free version, however as I
haven't installed the programme I can't say for sure that this is the
only restriction.

I'm not sure of anything. In fact, I'm really quite confused as I'm
completely out of my element when it comes to debugging Wi-Fi networks.

I haven't had the problem for a full five days yet, but since I can't
unbrick my Netgear Nighthawk AX8 AX6000 Nighthawk Mesh Extender Model
EAX80, I've had to learn a lot of Windows network debugging commands. https://www.downloads.netgear.com/files/GDC/EAX80/EAX80_UM_EN.pdf

It's confusing to me when I have to work with ports & MAC addresses more
than with IP addresses when trying to debug why a mesh extender is failing.
arp -a | findstr 192.168.1.
192.168.1.250 3c-37-86-fa-4f-9e dynamic

Almost all of that I don't really understand because I'm only trying to
figure out what to fix so that I can make the mesh extender work on my LAN.

Alls I really want is to find a network-debugging tool that will tell me
what is going on when one mesh extender works while the other does not.

Luckily, I happen to have two of those EAX80 units on my network, where one
is working perfectly but the other is not working yet - where I'll term it 'half bricked' given it shows up on the network - but it won't work right.

So I put the bad EAX80 into recovery mode to try to flash the firmware. https://www.netgear.com/support/download/?model=EAX80

But Windows nmap network discovery commands are really complex for me. https://nmap.org

At first I tried tftp flashing (with & without the powerful freeware GUI).
But it's really hard nowadays to find the tftp gui as they're all dead. https://pjo2.github.io/tftpd64/
https://sourceforge.net/projects/tftpd64/ https://sourceforge.net/projects/tftpd/

But I thought I finally found where the TFTP GUI moved to but it failed. http://www.tftpd64.com/

It didn't matter as the EAX80 won't allow tftp port 69 firmware uploads.
nmap -sU -p 69 192.168.1.250
69/udp closed tftp

tftp -i 192.168.1.250 put firmware.chk
Connect request failed

So I have to use NMRP flashing freeware but this is uncharted territory. https://github.com/jclehner/nmrpflash/releases/latest

Not only do I need to deal with obscure ports & MAC addresses, but I even
have to refer to strange network naming conventions I've never used before.

nmap -A 192.168.1.250
MAC Address: 3C:37:86:fa:4f:9e (Netgear)(sometimes Epigram!)

nmap -sV -sC 192.168.1.250
53/tcp open domain dnsmasq 2.78

An example is you need to know the "net name" to flash with NMRP.
nmrpflash.exe -L
net9 192.168.1.22 00:13:ef:30:0a:6f (Wi-Fi)
net5 169.254.243.239 02:00:4c:4d:4a:50 (Npcap Loopback Adapter)
net8 192.168.1.100 00:26:55:4a:19:cb (Ethernet)

nmrpflash.exe -i net8 -f firmware.chk
Waiting for Ethernet connection (Ctrl-C to skip).
Advertising NMRP server on net8 ... /\/\/\/\/\/\/\/\/

Waiting for remote to respond.
Remote finished. Closing connection.
Reboot your device now.

The timing constraints are awful and mostly wild-assed guesses at how long
to hold the paper clip, when to turn off power & when to turn it back on.

But even after flashing, I can't connect wirelessly to the mesh extender.
netsh wlan show networks
netsh wlan show networks mode=bssid
netsh wlan connect ssid="NETGEAR" name="NETGEAR"
There is no profile "NETGEAR" assigned to the specified interface.

Nothing in the help files seems to be working for me in this problem. https://kb.netgear.com/29746/I-can-t-access-www-mywifiext-net-what-do-I-do

Unfortunately, even DD-WRT or Tomato or OpenWrt firmware doesn't seem to
exist for the EAX80 extenders (apparently due to use of Broadcom chips).

So I'm stuck with trying to figure out how to unbrick a Netgear mesh
extender where I have a good one to compare against but I'm dealing more in ports and Transport Layer Protocols and Ports and MAC addresses than in IP addresses.

Which is why I needed freeware similar to that of Acrylic.

In my searches to find some way of telling me the information I need to
debug why the one bad mesh extender isn't working, I ran across this report-generating native feature of Windows which is useful to try once.
netsh wlan show wlanreport

That detailed report includes all the SSIDs you've connected to in the past three days including all failed connection attempts, errors, etcetera.

Open the graphical report in a web browser on Windows using this URL. file:///C:/ProgramData/Microsoft/Windows/WlanReport/wlan-report-latest.html

Anyways, my biggest problem is I don't know how to debug when one mesh
extender is working fine while the other exact same model extender fails.

I was hoping Acrylic or some other Wi-Fi analyzer would help in the debug.
I will find out soon if it's only a five-day license or if it still works.

I was just pointing out that you might have downloaded the Pro trial
version of Acrylic rather than the free one.
