GS105Ev2 not getting IP Address from DHCP
I have a GS105Ev2 that I plugged into my network today. All I have plugged into that is the cable to another switch and my laptop. My laptop gets an IP address from DHCP (192.168.87.43) just fine but...

Here's what I had to do once I figured out the issue was some jacked up firmware:
1. Install ProSAFE Plus Configuration Utility on a windows system
2. manually configure the laptop to use 192.168.0.210; netmask of 255.255.255.0
3. Download the latest firmware from: https://www.netgear.com/support/product/GS105Ev2.aspx#download
4. Apply the firmware using ProSAFE Plus Configuration Utility
5. Factory reset the switch
I was then able to browse to the switch and use the default password (password) to get in.
Thanks to everyone that helped.

You can't reach the 192.168.0.239/24 IP address because your LAN subnet is configured to 192.168.87.0/24 - two different IPv4 subnetworks.

The discovery does work on a different protocol - it can discover switches (while connected to the same LAN or broadcast domain). As explained above, the Netgear Switch Discovery Tool does use IPv4 to connect, resp. call a web browser with the discovered IP.

Double check the subnet is set to 192.168.0.0/24 (255.255.255.0) - if there is a smaller mask, the IP connection might fail again because of potentially multiple IP subnets again.
To exclude the impossible, try another port; try another network cable, ....

"You can't reach the 192.168.0.239/24 IP address because your LAN subnet is configured to 192.168.87.0/24 - two different IPv4 subnetworks."
Yes, I even stated I didn't expect that to work.
That's also the problem, why is it 192.168.0.239 and not getting an address from DHCP???
"Double check the subnet is set to 192.168.0.0/24 (255.255.255.0)"
I did.
I also tried multiple cables/ports. It's not working with DHCP.

One more idea (silly me checked the GS108Ev2 before): Does the discovery tool show a switch firmware version version number before 1.3.0.1? Reson asking is because of very early firmware (1.2.x.x) does not come with a Web GUI, and it was mainly an early factory firmware. In this case (I hope you have a Windows system at hand!), you need to go the hard way and use the ProSAFE Plus Configuration Utility _before_ the curent 2.7.2, e.g. https://kb.netgear.com/000051197/ProSAFE-Plus-Configuration-Utility-v2-5-3 for backward compatibility.

It shows V5.4.0.3 ... That doesn't seem to be a valid firmware.
