XB7-CM and HP LaserJet Pro color M451dw

This printer has ALWAYS been a bit of a challenge to set up with a new network but the XB7-CM is challenging me like no other past router.

I have a thread going here at HP's site: click here

Bottom line thus far is I have tried a myriad of things to get the wireless printer connected to the new wireless network.

The previous XB6-T was just fine.

I suspect that it might have something to do with this XB7's lack of ability to assign 2.4 or 5 GHz.  It chooses for you.

I'm pretty certain I installed it on the 2.4 GHz frequency with the XB6-T.

I finally did a "Restore Defaults" on the printer and that actually fixed it being permanently stuck in "Error 79" mode.

Now I can't get the wireless of the printer to link to the router.  Even WPS results in a temporary Error 79 mode.

Every attempt to get the wireless going results in Error 79 on my printer.

Anyway, any thoughts from the collective here?  This is quite frustrating.

The two WiFi bands have recently been combined into one with the Comcast gateway devices. Some devices get confused and don't know how to see / talk to combined bands.


If you are not using any Xfi Pods, you can try separating the 2.4 and the 5.0 bands and give them two different broadcast names / SSID's;

Associate the printer with the 2.4  band's SSID (broadcast name) and password.

Cool.  Thanks for the information.

I'm going to go ahead and shut down the 5 GHz band and see if I can get my printer setup with just 2.4 GHz available.
