One of the critical features missing is the ability to set "WPA2 Only" as your wireless security protocol on the Deco M5 (which is what I have) and many other Deco units. The device defaults to WPA/WPA2 mixed mode and *cannot* be changed. This means the device always has the older, inferior, and insecure WPA mode available to all potential clients. iOS and Android are about to roll out an update on all their phones which will cause them to warn and then refuse to connect to any device still using the out-of-date WPA protocol. So, when that happens, these devices will virtually be useless. Many devices already have safeguards built-in that refuses to connect to any network still running WPA… so odds are you may have a handful of smart devices that won’t work with this system out of the box.

Users have been trying over and over again to get some kind of response from TPLink about this issue, and it's either ignored or we're told: "we'll take it under advisement". Why can't you give us what other routers and devices have been giving us for 10 years? I see you have bee doing firmware updates, but for features nobody is asking for (like "smart" commands). 

I'm giving it another week before I will simply have to return my Deco M5 (so I am within my product return window) and get another product. It's absurd that this feature has been an afterthought. Especially when you consider iOS and Android are just about to release the new versions of their software which will render these devices useless. Basically, most Deco units will soon become nothing more than glorified paperweights.

If you can't offer us any solid indication as to *when* an update that allows us to choose "WPA 2 Only" will be available, I strongly encourage EVERYBODY here to return their devices and get another brand. It's simply not worth it having such a gaping security hole in their network, no matter how much more "convenient" TPLink thinks it is for the end-user.

As somebody who can also provide some insider information: There are already numerous high-profile tech blogs and review websites lined up with articles drafted and ready to publish as soon as the iOS and Android updates go live to expose all devices forcing users to use WPA. It's going to be bad news for TPLink when all these articles recommend to people to trash or return their Deco units. Things are going to get very interesting for TPLink in the coming days.
