All right, my first guess was wrong - this looks like an initial or very early GS105Ev2" switch 8-)

From how I read the initial firmware 1.2.0.5 had no Web UI - it was added with GS105Ev2 Firmware Version 1.3.0.1 :

===
New Features & Enhancements:
Supports Web GUI management.
Using the Download Link below, download and extract the new firmware to a convenient place such as your desktop. The filename after extracting is GS105Ev2_V1.3.0.1.bin
===

Looks li it's time to make the **** utiltiy workable on your Windows 10 system.

> Where is the idea coming from there is a username and a password required?

Well, after having search on Netgear web site which password is supposed to work, I end up trying all the password for all the Netgear devices as none did work.

So step-by-step:

- macOS 11.0.1 (also tried with Windows 10 64bits without any luck, just for info)

- GS105eV2 is not connected to any LAN or server, only to the Mac (I tried different switch port, same results, just for info). It is a GS105eV2 version, as written on the back sticker:

sticker

- I've factory reset the switch several times (seeing all the led flashing simultaneously green after about 6 seconds)

- Mac Ethernet port configured as static IP, as follows:

en8: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=50b<RXCSUM,TXCSUM,VLAN_HWTAGGING,AV,CHANNEL_IO>
inet 192.168.0.210 netmask 0xffffff00 broadcast 192.168.0.255
media: autoselect (1000baseT <full-duplex,flow-control,energy-efficient-ethernet>)
status: active

- using the latest downloadable "NETGEAR Switch Discovery Tool", Version 1.2.102 (1.2.102), which sees the manageable switch as follows:

discovery

- the switch is discovered on the expected address

- clicking on "ADMIN PAGE" button gives:

- the user is prompted for a *login* and a password. I let it blanck initially, as as "password" which is supposed to be the default password, I tried many times, and ended up trying "admin" and other Netgear default logins without luck. So here, I've entered "password" (all lower cases), and the browser displays the same login again and again, as the password is rejected.

- I tried with Chrome, after Safari - same issue, password is not recognized

- I tried from the command line, just so that you can see that I do use "password" and nothing else:

eblot@thurso ~/Downloads [6]> wget --http-user='' --http-password=password http://192.168.0.239/

Connecting to 192.168.0.239:80... connected.
HTTP request sent, awaiting response... 401 Unauthorized

Username/Password Authentication Failed.

You can see that there is no intermediate device between the Mac and the switch, as the Mac knows about the switch mac address:

eblot@thurso ~/Downloads [6]> arp 192.168.0.239
? (192.168.0.239) at 20:c:c8:41:a1:39 on en8 ifscope [ethernet]

At this point what should I do?

Looks all fine, except of the wget test - this is a Web form, not a http basic auth header - which can't succeed.

Reads or feels like a browser compatibility thing to me.

It really looks like a HTTP basic auth header to me, not a web form. The login prompt rendering is different from one browser to another, and curl (and Safari debug console) reports the following headers:

eblot@thurso ~/Downloads> curl -D - http://192.168.0.239/ HTTP/1.1 401 Unauthorized Connection: close WWW-Authenticate: Basic realm="Switch" <html><head> <title>401 Authorization Required</title> </head><body> <h1>Authorization Required</h1> <p>This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required.</p> <hr> <address>Web-Smart Server</address> </body></html>
If I'm not mistaken, WWW-Authenticate: Basic realm="Switch" is the basic HTTP authentication header.

> Reads or feels like a browser compatibility thing to me.

Well, it fails with Safari, it fails with Firefox, it fails with Brave, it fails with Chrome.
What browser is it supposed to .. not fail ?

  The Netgear Smart Managed Plus switches coming with a web UI do not support http basic auth - it's always a Web form calling some cgi lightly encrypting the password for the travel over the plain text http connection.
  
  Does your switch show a Netgear branded and designed login form (probably not), or a browser side basic auth pop-up (probably not), or does it come up with a either an empty page (most likely)?
  
  Does the Netgear Switch Discovery Tool show a firmware version like v5.4.0.3?
  
  What is the complete model designation of your GS105Ev2?
  
  Here is my guess following the second morning coffee: The switch as you bought it is _not_ a Netgear version as sold and marketed with the GS105Ev2 designation - it's coming from some batches intended for an OEM, and has no Web UI (and probably other restrictions) and might be labeled as GS105E-2A1NAS.
  
  There are the official model/packaging versions available.
  GS105E-200NAS North America and Latin America
  GS105E-200PES Europe
  GS105E-200AUS Australia
  GS105E-200UKS United Kingdom
  GS105E-200JPS Japan
  
  It's possible to change the firmware to the standard Netgear one using the (almost obsolete, but OK for this purpose) Netgear ProSafe Plus Configuration Utility (available for Windows only I'm afraid).
  
  This was discussed e.g. here https://community.netgear.com/t5/Managed-Switches/GS105Ev2-FW-reads-v5-4-0-3/m-p/1562266/highlight/t... and several times again since.
  
  PS: Never had one of these OEM units, so didn't checked any of these.

    It shows nothing as it prompts for authentication first.
    
    > Does the Netgear Switch Discovery Tool show a firmware version like v5.4.0.3?
    No, the reported FW is 1.2.0.5
    I've attached some photos in a previous post, but although netgear web site accepted them and reported no error, they never show up in this thread (maybe it's a fake OEM Netgear support site ? :-))
    > What is the complete model designation of your GS105Ev2?
    I'm not sure where I can find this information, and it seems I'm not authorized to post a picture (I will try again)
    The sticker on the back reports:
    
    NETGEAR
    ProSafe (c) Plus Switch
    5 Gigagit ports GS105Ev2
    (FCC/CE, etc logos)
    MSIP-REM-NGR-GS105Ev2
    DEFAULT ACCCESS

    Serial: 3MX1435ED00470
    Made in China 272-12044-01
    
    The PCB as a silk white marking: 2976453602
    and a couple of sticker. One with the MAC address as a datamatrix (same as on the back sticker)
    The other sticker contains a barcode with
    
    RM14095085640957
    5508011305 REV:0
    
    On the bottom side of the PCB, there are additional silk white markings:
    SH1 94V-0
    E248779

    I have not kept the packaging (as it used to work).
    It comes with a EU power dc adapter, which has its own Netgear sticker BTW.

    I'll try to re-download it, but for some reason it refuses to execute on my Windows 10 /x64...
