Using a Netgear EX6120 wifi extender to reach to a somewhat remote igate with the following config:
TTGO_T_BEAM_V1_2
Igate Version date: 2025-06-20
Build date: 2025-06-19 16:16:27 UTC

the igate will not connect to the extender (other devices have no issue connecting) and always uses the second SSID in the Wifi Access list.
The extender SSID and password are different than the router . I have tried Address reservation and normal DHCP for the igate in the router, both produce the same result.

Is there something unique about connecting to an extender that the igate is not supplying or is the SSID connection period too short?

Thanks,
N2VEN

does the extender has " " or special characters in the SSID or Password?

SSID is: ext_zach and password contains only letters and numbers (11 characters long). The second SSID (which it does connect to) is: zach_net and password has only letters and numbers (9 character long)

can you avoid the "_" and test it on the repeater SSID ? (i've seen some esp32 had trouble with them on SSID and check that the SSID and PASSWORD of the first one do not have any " " before or after the characters too

Removed the _ in the SSID no change. Confirmed there are no " " before and or after the SSID or password

2.4G and 5G capable, I am using the 2.4G path to the repeater (selected by use of the SSID). I have also tried turning off the 5G path in the repeater, no change.

how many WIFI are defined and saved on the board?

save just the needed one and delete all the others (also use the needed one in the first position = don't have a empty wifi defined at first)

Only two are defined, first one is the repeater, second is the primary wifi router.
If the first and only one is the repeater, the igate goes into AP mode (192.168.4.1)

I have loaded Meshtastic FW and it also will not connect to the repeater! Must be something in the ESP32 wifi code that is not handling things properly, your thoughts?

nothing strange there besides the marks on one corner but this should not affect the wifi connections neither the wifi to one SSID and others don't (like the repeater)

maybe a reset of the repeater (as some do save for some time clients to avoid?)?

i'm running out off ideas :/

I agree, I'm out of ideas also that's why I sought your help.!
I am going to look into purchasing a different chipset board, is there one you could recommend?

different LoRa board? or different WiFi-Repeater ?

I configured the repeater in AP mode, the t-beam can now connect to it. Although not ideal for my application (since an ethernet connection is now needed) I can move forward.
Still a mystery as to why repeater mode will not work.
