I believe from what you have said that your issue is you are not aware of what how to deal with connecting to your Magni once you have told your Magni to connect to your own wifi.
So lets say that you used pifi to add YOUR wifi network with SSID of ‘mynetwork’ so I can talk about what to do.
If the Magni connected to ‘mynetwork’ it will no longer present an ‘access point’ for it’s OWN network because there is no need. The Magni either uses the Pi wifi to present it’s OWN wifi Access Point, AP, OR if it is told to join your network it simply joins and gets an IP address from YOUR network access point (normally this is some Wifi Router that connects to the outside Internet.
So IF the Magni connects to your Wifi with your unique SSID (network name) the magni will be on your own network.
You must then find where the magni IP address was assigned. A rather recent change is to have this show up on the little OLED display but we are not fully shipping this little display quite yet and it is not automatically built into our software to always run the display so I don’t think that is ok yet.
What you then must do is have some OTHER device like laptop or Windows machine or an android phone and then have a tool on that device to ‘SCAN’ and show you the IP address of the Magni.
For Windows on that network I install and then use an app called ‘Advanced IP Scanner’. Once installed IF your windows machine is also on the same wifi of ‘mynetwork’ you just hit ‘SCAN’ and look for any raspberry Pi or look for hostname like ubiquityrobot to find it’s IP address that your own router assigned to it on your network.
If you have an android phone you can connect your phone to ‘my network’ and then use an IP scanner such as my favorite, ‘Fing’ available on google Play Store. This too will scan your network IF the android phone is in this case connected to ‘mynetwork’. Look for a raspberry pi with a name starting with ‘ubiquity’.
If you connect a linux laptop to ‘mynetwork’ you may then use ‘iwconfig’ to look up your first 3 numbers of your IP address and then use ‘arpscan’ so this is the most ‘unfriendly’ method but it does work. Lets say you connect your Linux Laptop to the same network SSID (name) you told PiFi to connect to. Lets say you run ‘iwconfig’ and it tells you your WIFI IP starts with 192.168.1
You would then on that linux box type: sudo arp-scan 192.168.1.1/24 (I know this is MAJOR cryptic but that in face is HOW linux is in general). Geeks LOVE cryptic command line stuff!
So in SOME way you find your IP address and after that you would use ssh like this (example IP)
Hope this helps. I think I will add the above to the Learn pages for others in the future!
