we have an implementation of Wlan distributed throughout several plant's, where there security implemented is:
1. SSID Hidden
2. 128 Fixed WEP Key
3. Cisco ACS with registration of MacAddress's
And we are then doing authentication based on Mac-Address.
We know that this is really a not safe solution, but what you would recommend, considering that we are Running Microsoft Active Directory, but avoiding the use of Certificates.
Thanks for any recomendation,
