Can someone help me how to deal with this strange issue. Suddenly, a Windows and Android device cannot connect to 1 wifi end point (even after restart Android and restart the router, and check the password, doing forget and reconnect, etc.). It still works with another end point on the router. For the end point that the Android and Windows do not work (wrong password), a Samsung TV and IPhone work fine.
Any help is appreciated.
To help, we need to see the configuration.
Please connect to your OpenWrt device using ssh and 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:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
Thank you for helping. I am sorry for not getting back yet. I have been very busy but I will get back to this ASAP.
Thanks to your help, when looking at the wireless configuration using command cat /etc/config/wireless, I saw an odd option that other wireless network does not have "wpa_disable_eapol_key_retries '1'". When I unchecked that and applied, everything works! I don't know why suddenly it stopped working.
