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.

My laptop gets an IP address from DHCP (192.168.87.43) just fine but the switch has the factory default (192.168.0.239). When I try to browse to http://192.168.0.239 it fails (as I expect it would).

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 NETGEAR Switch Discovery Tool does see it but I can't get to it. I've rebooted and factory reset many times and it won't pick up a different address. 

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, ....
