WiFi will not connect unless some laptops ...

Some laptops like the Lenovo X220 / X230 do not connect to WPA2 on RV220W if we keep the configurations that seem standard today: 802.11n and automatic channel selection. And although Cisco does not see it that way. You will not find any trace of the possible solutions on the Cisco Support site, just those who complain.
It took several calls and stimulus to the support center to get a recommendation configuration: select a frequency or a fixed channel and preferably use the standard B / G instead N. implement Cisco's competitors today successfully N standard versions that operate at 300 or 600Mbps, but not Cisco. Similarly you can not activate 2.4GHz 5GHz frequencies and at the same time.
Do not attempt to deploy either 2 virtual AP with WPA2 authentication on one and EAP-TLS on the other, it does not.
The only thing that saves this case is part of the router / firewall whose configuration is similar (some) professional tools. The price is almost double that of other boxes on the market: it is not worth it.
