wall mounting of WAC120?

I don't believe so, it is meant for desktop use.

@1_Heiko: Since the design of the WAC120 is for desktop deployment... I would recommend that you place it as high as 5ft. or more up from the floor. However, it would be your option if you want to improvise a mounting bracket if ever you really want to place the WAC120 to be mounted at the ceiling or side-wall. :D

Thanks a lot.
I hooped there is a solution I just didn't see.

seems a wall mount is now included in the package!? http://www.downloads.netgear.com/files/GDC/WAC120/WAC120_IG_GR_12Feb2015.pdf

unfortunately, support chat is unable to give any information about it. they didnt even know that there was no wall mounting before.
any ideas on how to get one without buying a new access point!?

I see, it's indicated on the package content as well.
