We do have plans for a Portal Authentication on Deco in an upcoming firmware (Version 1.9).  We do not have any details or know release plans for this new frimware version.  Also keep in mind that plans are just that a plan.  We cannot gaurantee it is comming until it actually launches. I don't forsee it not comming but there is a chance it could be delayed.  Older models, like the Deco M5, generally receive new featrures later in the deployment cycle too.
