I have an RUT955, f/w RUT9_R_00.07.04 just been installed at a remote site 200km away.
Was operating on the bench, connecting via WiFi (we created a new AP with the same SSID and password as the remote site).
Has a cellular SIM as backup.
Now that it's at the remote site, it's not connecting via wifi.
Network scan shows the nearby WAP as 69% signal (-62dB, Quality 48/70), same SSID, channel 8, mode Master, Encryption "mixed WPA2/WPA3 PSK, SAE (CCMP)"
When I look at WIFI status, it shows this configured interface with the correct ssid, "interface status" is Running in green, with 4/5 bars, followed by 0%. Says Mode: Client, Encryption psk2+ccmp
I've confirmed the password by checking on the WAP itself and copy/paste even as well as typing (carefully).
I've checked the Wireless Security for this connection, got Encryption WPA2-PSK (also tried WPA-PSK/WPA2-PSK Mixed Mode and WPA2-PSK/WPA3-SAE Mixed mode), and No Encryption.
I've tried Cipher Auto, Forced CCMP (AES), and Force TKIP and CCMP (AES).
Nothing seems to get it to actually connect. What am I doing wrong?
The WAP is an ancient DD-WRT and other things are connecting (and connected) to it ok.
I've tried disabling this interface, then going to Scan and "Join Network" but I just get an error saying "Maximum number of one client for one device allowed. To specify few possible clients use Multi AP" but it won't let me enable multiAP either?
I don't know where to go from here, and being 200km away and in a locked compound, I can't easily get to it.
