Just what I wrote. When I pressed the button to toggle DHCP from OFF to ON, it would not change. Only after I did the SCPI command did it change. (Edit) Only after I did the SCPI command above was I then able to change it on the SDM3055.
The SDM3055 came pre-installed with 20R2.
When connected to my network, everything in between it and the main router before the modem - 3 switches, a mesh network used to bridge the internet connection wirelessly, 4 lab devices, 3 computers, 3 NAS, a printer, an AP, and all devices connected to the mesh network - looses internet connectivity, and even some LAN devices aren't accessible (NAS, networked printer).
I thought it might have been cause of the very different default IP address in my 192.168.xxx.xxx network. After I gave it a static IP, both in my router used for DHCP, and in the SDM3055. It even showed up in an IP scanner "Texas Instruments", and I could use it with EasyDMM. It seemed to work for a bit, but did end up breaking the network eventually.
I would consider myself advanced when It comes to networking... However, I do not have the time nor the patience to try and troubleshoot it. As far as I can tell, the SDM3055 works perfectly, and if I really need the ability to monitor it remotely, I can always try a separate ethernet to wifi bridge or something.
