WPA2 Enterprise with Windows 7
Hello I am being thrown into a project head first and trying to get up to speed. From what I have read I need to have a certificate for using WPA2 Enterprise. I would prefer not having to go to each machine spread geographically around a fairly wide area to install a CA certificate. Is it possible to use a purchased certificate so that Windows 7 recognizes it and will connect? I think I only need one certificate for the RADIUS server, but still unsure. Does it work with multiple SSID's from different AP's? What about redundant RADIUS servers? Do I need a certificate for each? I have googled and not seen anything definitive for these questions. I will continue to search, but hopefully someone who has this sort of setup working can answer those questions and I can carry on with getting it setup. Thanks Michael

Yes

No. The CN in the cert doesn't get verified against a URI like it does in something like https://. -Arran Arran Cudbard-Bell <a.cudbardb@freeradius.org> FreeRADIUS development team FD31 3077 42EC 7FCD 32FE 5EE2 56CF 27F9 30A8 CAA2
Hi,

yes, you can do that - but youll reduce your security profile

yes, yes, add multiple RADIUS servers to your NAS/controllers and no, can use the same cert alan

You can use such a certificate, but you still need to manually mark it as trusted for WPA2 Enterprise purposes (none of the installed CAs qualify "autoamgically", trust is configured explicitly). There's more to configure client-side than just install a CA certificate or mark it as trusted. Things like anonymous outer identity are nice features, but involve ticking the right boxes on the machines. There are tools which do that for you. Windows group policies can do it for Windows clients. For BYOD scenarios, web services like https://802.1x-config.org cover a wider range of clients (free, with some paid-for optional upgrades: https://802.1x-config.org/tour4.php ). If your project is by any chance related to the eduroam roaming consortium, your instance of this web service would be https://cat.eduroam.org which has the richest feature set, entirely for free for eduroam participants. Greetings, Stefan Winter

Okay, so if I need to touch every computer anyway there is no real advantage to getting a commercial certificate.
There's more to configure client-side than just install a CA certificate or mark it as trusted. Things like anonymous outer identity are nice features, but involve ticking the right boxes on the machines. My main purpose is for logging of what AP is being used by what device and when. There are several laptops running Windows 7 and/or 8 which are not on a domain so group policies are not an option. There are also a number of BlackBerry smartphones which I can control from the management server. For those I should be able to push out a certificate and send the updated WiFi configuration to them automatically. The AP's are various D-Link routers running DD-WRT. I put together a test setup, but I had to jump through some hoops to get a Windows 7 machine to connect, but that was because of the cert not being recognized.
I guess my next step is to generate a CA cert etc.
