The confirms it's a not a hardware issue at least. Which makes sense since the WPA auth should all be in software.

Yup iwlwifi can only be a client currently.

@stephenw10 Which of all the options, I review friend, thanks

The only WIFI NIC I know of that works in the 2100 is the WLE200NX. Most are simply not recognised though.

@Ehall_Pass_Pro maybe by implementing FreeRadius using a unique barcode / QR code on the hall pass as the ID and using radius on the SSID. In FreeRadius you could also limit the number of simultaneous connections to 1. You'd just then need to enable / disable the firewall rules associated to the SSID based on the time period.

@provels said in WLE900VX in pfSense 2.7.2?: (WLE600vx) I don't expect that work, that's also a .AC NIC. What are you using that in?

Is that only at the initial connection? Or when it rekeys?

Mmm, it won't be an easy config conversion but you would at least get current code, security fixes etc. And, yes, the ALIX was/is pretty much indestructible! https://openwrt.org/toh/pcengines/alix

@stephenw10 Thank you for your reply. I've purchased GW-R86S-T3 to replace my aging hardware since I'll be getting fiber internet soon and old hardware would not be abble to handle it. I used Wi-Fi card in my old box as a client to connect to my next door neighbour's AP with whom I have an agreement, to connect to his Wi-Fi in case my main ISP is down. Esentialy, Wi-Fi acts as a fail-over WAN automatically switching as needed. I was hoping to replicate the same setup with new hardware. Hopefully, my current hardware will get some support with some future version of pfSense.
