Hi @mobb,

Yup, just get the EAP225V3 for $59 instead (in the USA).  Unless you expect a super high density of clients (>40 / EAP) in a commercial setting.  Even then, I don't know that anyone's actually proven the EAP245 (w/4x4) is more performant under high user load.  it _should_ be, but is it?  Looking at Small Net Builder the performance of MU-MIMO across a number of product lines (granted mostly consumer) seems pretty sketchy.

EAP225V3 firmware gets updated pretty frequerntly.  EAP245 not so much.  EAP265 is "brand new" -- haven't seen any reports of users on this board yet, unless I missed them.

IMHO, better to go cheap now on the 225's, and plan to upgrade to the 620 or 660 in a year or so once the product (is released) and its firmware stabilizes.

Is this a commercial or residential deployment?

Educational environment with a lot of class rooms and old 802.11n access points with PoE, so the EAP245v3 or the EAP265v1 would fit perfectly. It seems I will have to wait until the first real benchmarks arrive and see whether there is any real difference between both access points. I do not want to waste money.

Hi @mobb,

If you have an AP in every classroom (not sure if that is true), and 50 or fewer clients per classroom / AP, the EAP225V3 will most likely be just fine -- and significantly better than your current equipment. 

Regardless re: 225, 245, 265, Don't forget to plan for Omada Server or an OC-200.  With the new SDN software now, you might also want to consider upgrading to an SDN compatible PoE switch for enhanced management.
