Weak Security WiFi on iPhone

Will the new update that came out today fix the "weak security" issue??

You fix the weak security issue by making the security on your WiFi network more secure.

No, this warning has nothing to do with your password. Is your router set to WPA?

After changing router settings you need to forget the network on each device, then reconnect to it.

My 2.4ghz channel doesn't show the security warning on all upgraded IOS devices. My 5ghz channel shows the warning on all upgraded devices.

The security settings for each bandwidth in the router need to be set separately.

If you set your router to use WPA2 as specified on your iPhone and you still have the weak security message, all you have to do is shut off the phone and turn it on after 20 seconds. The message will disappear.

NO, it’s not an Apple issue. It’s an issue in your mis-configured router, which has always had weak security. You just didn’t know it until now. You can ignore the warning and your network will continue to have weak security. There’s nothing Apple can do to fix the incorrect settings in your router or in your range extenders, if you have any.

Just remember if your change to wpa2 your older products might not work work ? , this is only a issue with ISO 14

You would be talking about VERY old products. WPA2 was first introduced 16 years ago.

And it isn’t an issue with iOS 14. The network has always had weak security. You just didn’t know it.

So, a problem with that security mode (WPA2 AES) is that it can be too restrictive on people's devices. I work in IT and I have seen many times where customers call in and report that their internet has been down for days or intermittent for weeks and once we update it to the "weak" security it resolves within minutes.

I prefer to have the settings set to WPA+WPA2 TKIP as it allows a more stable connection to the customers devices. I have found no issue having my network set to the dual protocol since I've changed. The only problem is that we don't have the ability to change to WPA2+WPA3. I don't think our system allows that at this time.

Just my input.

Maybe it’s connecting to a different network. Try forgetting the network, then reconnecting. Also, restart your router. If the problem continues: Settings/General/Reset - Reset Network Settings.

The iPhone “asks” the router what the encryption level is. Apparently your router is replying that it is TKIP.

update - turning bluetooth off fixed it for some reason!

Forget the network from your Mac, then reconnect.

The weak security message is never false. Did you forget the network on your Mac and reconnect?

Just downloaded IOS 14 and the same submessage "weak security" appears in my iPhone Wi-Fi. Spoke with my Internet Provider and told me the same Mr. Lang stated, "One possible downside. If you have much older devices that connect to the router that don't understand any security protocol newer than WPA, they'll no longer be able to talk to the router." The message won't appear in my vintage MacBook Pro (13" Late 2011) and an old iMac I have. Most likely because they do not have IOS 14 but do that make them less secure as well as my iPhone. I think Apple should have think a little more about this. If I update the router I make run the change of not being able to connect to Wi-Fi. Just waiting for a resolution on this. I cannot accept seeing a "Weak Security" message in my update IOS 14 iPhone. :(

Good analysis. “Weak security” is a threat to the network itself, not to devices using the network as long as the devices always use TLS/SSL connections, which is the default for all services on an iPhone. So if you use a public network that has weak security it is the network owner’s problem, not yours.
