HP 8600 PRO Printer and Gateway connection

If you have your wifi separated between 2.4G and 5G, make sure that both your printer and your computer are on the same one…..In my case, I think my printer only uses 2.4G wifi, so when I go to print, I need to make sure the computer is using the 2.4G wifi. 

The Wi-Fi set up wizard on the HP simply looks for the router name and then the user enters the passcode for that router. The T-Mobile router will not accept my HP8600 pass code.

According to a quick search HP support states - 

• 802.11 b/g/n – 2.4 GHz networks only

This means you will probably have to either separate the 2.4 GHz radio from the 5 GHz bands OR

You can add an additional SSID on the 2.4 GHz radio only (provide a name for the printer net)

Authentication type is “probably” WPA or WPA2 so include WPA/WPA2 authentication types

If you still have issues trying to get the printer to connect direct to the gateway and have a wireless extender or an older wireless router you can connect to the gateway then you can run only the 2.4 GHz radio on the older router and use either as a workaround for connecting direct to the gateway.

Note: Printers that only work on the 2.4 GHz band (especially older ones) can have problems connecting to and staying connected to the T-Mobile gateways via the 802.11ax protocol solution. Some other routers play nicer with this but the ones that T-Mobile use don’t seem to play nice with older 2.4GHz adapters. In some instances it comes down to older drivers not working well with the newer standard. I know it is supposed to be backward compatible but reality is old drivers are not always perfect either.
