MECH-WIFI
Brother · HL-L2350DW 32 ppm Wireless Duplex Mono Laser Printer with WiFi and USB Connectivity
The printer repeatedly loses its Wi-Fi connection, fails to connect to the network, or is not discoverable by computers and mobile devices on the network. Brother printers are known to have issues with 5 GHz networks and mesh Wi-Fi systems — they only support 2.4 GHz Wi-Fi. If your router broadcasts a combined 2.4/5 GHz network, the printer may have trouble maintaining a connection. Create a separate 2.4 GHz SSID for the printer or ensure your router allows 2.4 GHz-only devices. Check that the printer is within reasonable range of the router. On the printer's network settings menu, verify it has obtained a valid IP address. Assigning a static IP address to the printer can improve reliability. If the printer frequently goes offline, check for firmware updates from Brother's support website — several updates have addressed Wi-Fi stability issues.
