micksmith How about saying what it is you are trying to connect to, i dont think there are many mind readers around here, i connect to the hotspot on my laptop sometimes when i have it with me, and thats not a phone, so more info might be a good idea
HA2NON You can find the instructions on how to setup the openSPOT4 for both home and phone Wi-Fi connections in the user manual at https://manuals.sharkrf.com/openspot4/en/home-and-phone-wifi.html#page-top The instructions are same for other Wi-Fi devices.
N1VGR I had the same problem, then I switched the outgoing hotspot signal from 5g to 2.5g and it seemed to see the hotspot. This seems like a juvenile problem to solve, but it worked...
