Wi-fi troubleshooting
Note about 2.4 GHz networking:
- In most cases Wi-Fi routers automatically handle all devices
- But in some cases, wi-fi router may have two separate network names (SSID). In that case make sure to connect to the option without “_5G” in the name because the printer has 2.4 GHz Wi-Fi module and cannot connect to a 5 GHz Wi-Fi network.
- Usually the router doesn't need any configurations after this and devices in 2.4 GHz and 5 GHz can communicate automatically in local area network.
Note about the M587 S”XYZ” P”12345” command.
- Remember check and use capital letters if any in the SSID name
- Maximum password length: Maximum command length is 42 characters in the current display on-screen-keyboard version. If you have very long SSID name or password name, it may be necessary to shorten them.
- Wi-Fi network without password, use for example P”12345678” instead for the password.
