My business has 1 LED sign (signtronix) and a program on my laptop that I create what I want on the sign. I use 2 Ubiquiti Loco M5's for my laptop and sign to communicate wirelessly. For some reason it just quit working? I replaced both Ubiquiti's. I have tried everything I know to try and get them to work, I tried Pinging them, I tried only allowing IPv4 address, I tried changing the IP addresses in the admin settings. Does anyone have an idea what I could do? I know its a long shot but I figured why not see if someone here would have a clue. The sign works, the program works, the ubiquitis work, I can't seem to get them to communicate. Any help would greatly be appreciated.
