i bought new macbook air, 13" 1.8ghz lion preinstalled (latest model) our local apple store.

cannot mba wifi connect wireless n router (netgear wndr3700) @ 5ghz (dual band). using wpa2-psk (aes). when try join, "connection timeout".

other facts consider....

mba connects fine 2.4ghz part of router using wep no problem.

mba connects wireless access point @ 2.4ghz using wep fine.

have 1 month old 15" macbook pro, upgraded sl lion. connects fine 2.4ghz , 5.0ghz wireless routher. both before , after upgrading lion osx.

have several windows pcs connect 5ghz fine.

have done lot of searching on problem, cant find solution. again, 15" mb pro (with lion) works fine , has. before , after upgrade of osx.

of course, have tried standard stuff. rebooting mba, wireless router. changed wep , wpa keys, latest fireware, etc.

suggestions?
