After successful image reload, — No Ip addresses were changed from the screenshots. I just changed the wan from static to DHCP-Automatic. I have now lost all contact with the device, both the wan and lan side.

Does anyone have all the correct settings for an ECB-3500? Or even correct sittings for a router with a single ethernet port?

I’ve ordered the "hotspot in a box" to try and get this proof of concept done, as it needs to be deployed in a resort in Nantucket very soon.

I’m going go re-flash the ECB-3500 with the Sputnik ddwrt image which has been customized and tested with this device.

I may also reload the original build of ddwrt and try to get back to the working router with the exposed network.
