I have installed this LinkSys E4200 that I only use for wifi (I have a Sonicwall firewall externally).
Everything is working fine.
*Enable IPv6? Is default enabled, why?
*5Ghz AND OR 2,4 Ghz? Ipad works on 5Ghz when enabled, but my laptop or squeezebox don't.

-What network mode should I take ... and channel Width or Channel
*What wireless security, for best performance.
