Brother DLP2550
Unable to connect my printer to my home internet router; re: The authentication/encryption methods used by the selected wlan access point/router are not supported by your machine.
Do I need to update the software/fitmware on the printer to be compatible with the T-Mobile network?
This can probably be resolved by adding a second network (SSID) to your gateway, for your printer and anything else that you have trouble connecting to the default network. I think the default network is better for most things; but some things won’t connect to it. I always recommend setting up the second network with 2.4 GHz only, and WPA/WPA2.
T Life Instructions
Some devices, such as printers, have trouble connecting to the gateway’s default configuration.
You can have several Wi-Fi networks on the gateway. You want to leave the default network alone (2.4 & 5 GHz; WPA2/WPA3 and AES security) and add a second, dedicated 2.4 GHz network. This second network is for devices that can’t connect to the default network.
Using the T Life app on your phone: Tap Connect (at the bottom). Tap Things (at the top). Tap your Gateway. Tap the magenta button Manage. Tap Network (at the top). Tap the magenta + Add Network.
You should now have an “Add new network” page. Under General details, Enter a new Wi-Fi network name (SSID) and a password. Under Advanced settings, change the Frequency Band to 2.4 GHz. Under WPA Version, change WPA Version to WPA/WPA2. The WPA Encryption Mode should automatically change to TKIP+AES. Tap Save at the bottom. Connect your device to this new network.
Use the default network for your other devices, as much as possible. Note that WPA/WPA2 (on the second network) is less secure, so I recommend setting this network to be Hidden. You can hide it after you get your devices connected to it. (The Hidden switch is in Advanced settings, below WPA Encryption Mode.)
