Just realized of the new version of wapAC
Two Gb ethernet, more RAm, powerful quad-core cpu, well done !

I noted a dual chain 5GHz wireless instead of old triple chain, any disavantage ?
Any review about new model ?

Thanks

It's literally a cAP ac in a weatherproof case, so that's what you should expect.

Disadvantage of the dual chain is that triple chain clients will perform less in comparison with the old wAP ac.
But in my opinion the improvements outweigh this drawback.

Thanks for feedback,
I would expect a wireless improvement or at least other improvements with no wireless one, rather than a step back.....
Old wapACs were very good in 5GHz performances, let's see these new ones...
