Do you have access to a PC running WinXP? If so you should be able to update the M1XEP Firmware however depending on the current version it could take several Bootware and Firmware version in order to get to the latest. If you are able to determine the current Boot and Firmware email this to techsupport@elkproducts.com and we’ll need to send you some BIN files. You could try the legacy 1.6.26 https://www.elkproducts.com/m1-owner-support-downloads/ but no guarantees it will run on Win7 with the latest MS updates and allow you to connect.
