Hi.

I have hardware that can use wirless g and one piece of hardware that can only connect at wireless n currently I have the wireless connection setup to g+n.

Is it possible to have one key for g and a different key for n, if so, how do I go about setting this up?

Thanks in advance.

if you mean password ?
I doubt it as there both going to share the SSID to Identify the Wireless Network.

there's only one radio in the device, so using a different password/login wouldn't make
any difference to the wireless method - if you have a 'g' device, it will make the
'n' devices run slower too.
