Mireille,
The 792X (7925/7926) phone wifi phones are supported with the 6K. You are free to use them with any access points and protocols that are supported with the 792x phones. However note that Access points used will bear upon the reliability of the phones. The better enterprise grade access points you use with better roaming features, the better your call qulaity will be. With linksys, if they are consumer access points, you are going to get what you pay for.
