Hi,
Can we use WPA encryption with a WiFi network in Ad-Hoc mode?

I can use the RCM4400W in Infrastructure mode with WEP or WPA security. But I cannot get WPA to work in Ad-Hoc mode. I noticed that there are no comments in tcp_config.lib about this combination.

--Is WPA + Ad Hoc a valid combination for WiFi in general?
--Is WPA + Ad Hoc a supported on the RCM4400W?

Hi Carl,
Did you get anywhere on this subject? I have used the sample that was shipped with the system, and it worked without encryption. Like you, I failed to make it work with wpa enabled.

Managed to get WPA running under infra-structure mode, using DHCP. The code is taken from "\Samples\RCM4400W\TCPIP\PINGLED_WPA_PSK.C".
Good luck!

This is what we learned after looking into it:

infrastructure networks - no enc, WEP, or WPA may be used

Ad-Hoc networks - no enc or WEP may be used

Ad-Hoc networks don't typically use WPA because various networking devices either don't support WPA in Ad-Hoc, or support a flavor of it that is different from others. :mad:

So at least on the RCM4400W module, Rabbit didn't implement WPA for Ad-Hoc.
