Greetings. I recently upgraded my Linksys WRT1900ACS from 21.02.3 to 22.03.2. After the upgrade, some devices, such as Amazon Fire tables and Amazon Echo devices reconnected to the WiFi, but other devices, such as Google Pixels and Apple iPhones did not.
Any thoughts on how to troubleshoot this issue?
Start by sharing your config files:
Please copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
cat /etc/config/network

cat /etc/config/firewall
Thanks for the prompt response.

try changing your encryption to standard WPA2. Some devices have issues with WPA3 and WPA2/3 mixed mode.
Done, but no change in behavior:

I also saw a couple of posts about disabling 802.11w Management Frame Protection under the Wireless Security section, but that did not help either.
is there anything helpful from logread cmd?
OK. I think the cause might have been:
After saving the changes and restarting the interfaces, the phones did not connect. But I went back into the phone settings, and saw that they were giving a "bad password" message.
"But the password did not change"
On one device, I re-entered the password, and it connected. I went to another device, and clicked on the wireless network name to force it to connect, and it connected as well, without having to re-enter the password.
My guess is that the failed authentication attempts on the phones may have temporarily disabled the WiFi networks, but a reboot of the phones did not resolve the issue. It turns out that the phones just needed an additional, manual nudge.
I had tried grepping the logs for the MAC address of the phone, but nothing was appearing in the logs UNTIL I gave the phone the previously mentioned manual nudge.
