Lost access to Managed Switch via browser, prosafe utility & serial console port
I bought a used Managed Netgear switch Sept 2019 and have been using it with no issues. Recently I tried to login as I want to look at creating some VLAN's but noticed that there was no url to manage...
I reviewed again our conversation.
I have tried connectiong through the serial port again. The switch is set to DB9 I have the serial cable plugged into the rear of the device. I have checked in the device manager and can see the USB-SERIAL CH340 (COM5) device is working with no errors.
Since you tried using a DB9 console cable, this time, let's use the USB console cable that came with your M4100 switch package. Be sure that the switch at the rear part of the M4100 switch is set to USB console. For you to be able to use the mini USB port, you must install the USB driver on the computer. To download the Windows USB driver, click here. As reference, kindly read pages 22-23 of the M4100 Hardware Installation Guide here.
Also, try using another PC/laptop to further isolate the problem.

Just to verify. Since you bought the M4100 switch used already, were you able to configure a Management VLAN on it before deploying it to your network? If yes, were you able to access its web-GUI to manage it before?

I was able to access the Web-GUI for a few months after I bought it. At the time I didn't have the need for VLAN's but now I do

WOW. The drivers were hard to install as it was being blocked by UAC and Windows 10 security. Had to disable a few settings but eventually installed the driver. Followed the guide to connect. checked the COM port number. and connected the cable to the switch and flicked the DB9 switch to use the USB. I opened Putty and input all the settings in and it connected. Amazing. Now I need to research what to do next????
I'm thinking of doing a firmware upgrade and wiping the existing config to start again.
