Weak Security WiFi on iPhone

A new wrinkle. I’m back at my home house using a completely different router/modem -Comcast/Xfinity Arris TG1682G. I’m having the same issue. Both 2.4ghz & 5 ghz bands are set for WPA2 AES each but I get the error on the 5ghz band only. I’m still thinking that this message is from an issue with the iOS 14 upgrade. Two completely different locations and router manufacturers and only the 5ghz band produces the error. It doesn’t seem to impact functionality though.

That's the most illogical layout I've ever seen for a router. You choose a "generic" option of WPA/WPA2, but then specify with a radio button under that which security version you want to use. And it still isn't clear enough you've disabled WPA by choosing WPA2.

Wrong

i have 3 devices on iOS 14 and 2 still on 13. X. Router is WPA2. 14 shows weak signal. You can blab all you want, and it’s bull. it’s a iOS 14 bug. Out with the old bugs in with the new. Anyone having this issue, just give it some time. They’ll have a fix in an update. Unfortunately, out with the old bugs in with the new’ will still apply.

Again, i have to reiterate what i wrote at an earlier. This is most probably an ios bug, and they will eventually de-bug. I wouldn't go messing around with router settings, because things can go pretty wonky. Give it time, there'll be a fix.

He is suggesting that you go to System Preferences > Network and forget the network and connect again. If you go to the first screenshot in this thread you will see what he is talking about.

If you are directly connecting to your printer network then yes you will need to fix the security settings for that as well as your WiFi booster.

I have contacted Apple Support. I have tried shutting down my Mac and unplugging the electricity supply. I have caused my Mac to 'forget' existing networks and re-establish them. These remedies have not worked. I still have false information in network settings and the 'weak security' warning still appears.

Apple support has suggested 'Reset NVRAM or PRAM' but for me, I think this is a bridge too far. If it fails to produce a solution, we are left with an unfathomable software issue.

Actually, after assessing the issue, I think there is greater risk to my peace of mind than to my wi-fi network being invaded.

I had the same problem so ordered a new 3.0 router from Virgin. It arrived yesterday evening so I connected it. Guess what? Weak security... HELP!!!

Have you reported the issue to Apple with all of the details about your router? If not you may be waiting quite a while. I read your experiences, you are still far, far short of Lawrence's expertise.

Our Linksys Routers use the term "WPA2 Personal" instead of "WPA2 (AES)" or "WPA2-PSK (AES)" for the appropriate level of security.

Try telling your iPhone to forget the connection, then add it again as new.

You are right! The message disappeared for a while after I shut off and turned on the phone . The cause might be an extender, because the router is setup properly. I’ll check today the extenders.

The warning has absolutely nothing to do with being able to use the network. It is just a warning.

If you are using an ad hoc WiFi network for your printer check to make sure your Mac is not connected to it. And do you have a WiFi extender?

Ah. Sorry, missed that.

In that case, open System Preference > Network. Click the Advanced button. Click the Renew DHCP Lease button.

Had to do a little experimenting. My iPad and iPhone also had the same complaint. Yup, my router was set to WPA/WPA2. I had it that way because my wife's old iPhone (which we no longer have) wouldn't connect to WPA2.

I changed the router's setting to WPA2 only (no option for WPA3). Went back to the iPhone and it was still complaining about WPA. Turned the phone's Wi-Fi off, then back on so it would reconnect to the current setting. Still complained about WPA even though it was no longer being used by the router. Finally, I shut the phone down completely, waited a few moments and powered it back up. The security message was finally gone.
