Yes, this is a pretty major issue that TPLink has been informed about for months and has yet to provide any proper feedback or guidance as to when they will be rolling out a firmware update to fix this. Basically, they need to allow users to select what type of WPA security protocol to use. Users should be able to select "WPA2 Only" at the very least. However, most Deco devices default to WPA/WPA2 mixed mode and this cannot be changed. This mode is insecure and the reason why many more devices are flagging them as "insecure connections".

In a matter of days, these updates for iOS and Android will roll out to everybody and basically render most people's Deco devices useless. By default, iOS and Android devices will refuse to connect to any wifi network still using the older WPA protocol. 

If TPLink is unable to provide an update or at least specific guidance as to when an update will become available to fix this, I strongly recommend all Deco users return their devices and get something else. Otherwise, you are going to be left with both an insecure and virtually useless WiFi network very soon. 

Apple just announced that iOS 14 will be released tomorrow - Sept 16, 2020. 

There is no solution from TP link, so prepare. Starting tomorrow iPhones and iPads will start complaing about "weak security" and refusing to connect to Decos automatically.

I have the same problem with Deco M9 Plus, my iOS 14 device and Windows 10 said that my connetion is weak security. We need WPA AES support for Deco.

Hello All,

I just updated my iOS and started facing the same issue. I wonder a company like TP link doesn't have this security level check. How were even this deco devices rolled out without such security check. 

I don't even find to turn on the WPA3 toggle in the deco app like mentioned in the earlier comments. 

We request the company to roll out an update for all the decos as soon as possible, else the devices will stop connecting this wifi network and it is going to be useless. 

FYI : I am using deco E4R.

When can we expect to get this new update, right now you cannot connect to your ipad or iphone which is ridiculous.  You have known about this for some time, please supply us with a date when to expect the update.

@StormMJ Hi, what do you mean by: "all devices will stop connecting wifi network and it's useless"?

I have E4R + M3 and Iphone XR running on IOs14 and the only result of this issue is message "weak security" under name of Deco network in WiFi settings on my IPhone.

I can connect this network and it is running as usual.

Thank you for the update, The manual beta upgrade sounds cool, but I think I will wait for the official release, that would be more reliable. 

Would be awaiting for it.
