The subject line contains the action I am considering after losing the ability to contact my DGS-1100-24V2.

I started making some VLAN changes and the switch lost contact with everything on the network.  Following a factory reset I am unable to login to the switch to reinitialize it.

I am following the standard process of plugging into the switch, configuring a static IP of 10.90.90.xxx, Subnet 255.0.0.0.0, and leaving the Gateway field blank.

However, when I go to http://10.90.90.90, the web page times out.

Have tried multiple resets, Windows 10 & 11 PCs, and most of the ports on the switch.

Prior to the VLAN change the switch had been working flawlessly for the last two years.

WTF is going on here?  Why won't the GUI respond at the fixed address?

Also, I can't ping the switch -- anything sent to 10.90.90.90 times out.

It's like the thing has bricked somehow.  Is there some sort of super-reset I can run to try and bring it back?  Have watched several YouTube videos and they all show the exact static IP config that I'm using.

And now it seems to be back.  I'm not even positive as to what I did. 

I think I executed several resets in a row, like 3 or 4 consecutively before trying to plug the cable back in.  At that point I could suddenly ping its address (10.90.90.90) and the web GUI responded when tested.

Sigh.
