I recently purchased multiple GL-SFT1200s
I've set up a WISP connection to my home WiFi
On the Wireless screen I set up two SSIDs: OH2D02-2.4G & OH2D02-5.0G
both with the same password.
The 5.0 one shows up on my wifi analyser app, but the 2.4 one does not, even after a power off on.
I changed the SSID name from OH2D02-2.4G to H2D02-2 and could see the signal after a power cycle.
Then i went back and modified the SSID to OH2D02-2.4G and no 2.4 signal could be found.
I need to use these particular names!
Since your issue is not related to the original thread, so I split this post and to create new thread.
I tried reproducing this issue on my SFT1200 with v4.3.25, there seems to be work ok, both the PC and iPhone can search for SFT1200 which customize changed to OH2D02-2.4G SSID, and connect ok.
