GL-X750 Wireless Printing

I am trying to connect my Brother DCP-L2530DW printer to my GL-X750v2 (router mode, latest firmware) over WLAN however I am unable to get the printer to connect. The printer can see the SSID of the router however after inputting my password, the connection fails. Could anyone give me any help please? Thanks in advance…

Managed to get it working by changing Wi-Fi Security from WPA2/WPA3-PSK/SAE to WPA2-PSK. Not ideal but solved the issue. A bug perhaps?

It’s not a bug when the client device interface adapter doesn’t support a newer encryption/authentication standard. If that’s a security concern deal breaker, run some Cat 6 to a unit w/ a NIC.

Surely “WPA2/WPA3-PSK/SAE” implies backwards compatibility with a WPA2-PSK device? In this case the device only worked when the security was set implicitly to “WPA2-PSK”.

Correct me if I’m wrong but does that not suggest a bug?

Superficially it would imply one, sure… but the devil is in the details:

Wireless Network Security
WEP 64/128 bit, WPA-PSK (TKIP/AES), WPA2-PSK (TKIP/AES)(Wi-Fi Direct supports WPA2-PSK (AES) only)[1]

Combine the fact this is an 802.11n device & you’re experiencing first hand that a combined authentication/encryption standard (WPA2-PSK/WPA3-SAE) doesn’t always work on older tech. Not all radios/adapters are created equal. You’d have to contact Brother to confirm if it supports the minimum use of CCMP-128 (AES-128 in CCM mode) encryption algorithm (or other mandated spec) as in all likely hood, the 802.11n adapter doesn’t know how to handle such a ‘new mix.’

(Side note: It doesn’t matter what Wi-Fi encryption you use; it’s all compromised anyways.[2])
