XB7 Gateway will not allow HP WiFi printer to communicate

Up until yesterday, I had an XB6 gateway and all was well, except for the occasional "issue" with speed.

I switched to the new XB7 and everything reconnected to my WiFi networks (2.4 GHz and 5 GHz) without any issue.  Except for my HP LaserJet M451 printer.

I was able to connect to the network using the WPS feature. So the Printer is visible as a device. However, when trying to establish communication from a laptop to print over the WiFi network, it seems like the gateway blocks any traffic.

This only happened since getting the new XB7.   Also the IP address assigned by the Gateway is not a 10.0.0.XX but a 169.xxx.xxx.xxx series.

When I connect the printer using a cable, then the IP address is 10.0.0.XX

I have heard others migh be having the same issues with their WiFi Printers?

Re: XB7 Gateway will not allow HP WiFi printer to communicate

Had same issue - older HP printer did not like mesh of XB7.  It did work for a while when it conected to a pod 2 rooms away at 2.4G.  Can you put a pod close to it, and connect via ethernet.  Bet that would work and how I have had to connect some devices that do not like mesh or have no wifi.

 

I bought a new HP laserjet.....  fixed the issue

Re: XB7 Gateway will not allow HP WiFi printer to communicate

aha

Older printer - figures...

I have the printer connected to the Gateway via ethernet

in the situation I need to move away - I have Comtrend PoE plugs I can use

thanks

Seems like an ethernet connection for printing is more reliable anyway

 

thanks

Re: XB7 Gateway will not allow HP WiFi printer to communicate

some say you can hard code through the HP app, but i think it is a combo of wifi6, mesh, and older printer that got me...

I can try to force the IP address on the printer to be 10.0.0.x like all the rest of my network using the TCP/IP from the printer control panel.  But using the Comtrend PoE adapater which allows ethernet over powerline works great  - I currently use them for my Arlo hubs which need an ethernet connection.

Re: XB7 Gateway will not allow HP WiFi printer to communicate

Had exact same problem.Comcast techs seem to never of heard of it.Anyway i went back XBT6 after two days of trying to work it out.I believe the printer is too old to work with that router.I could not see where the XBT7 was any better,except has more ethernet ports

Re: XB7 Gateway will not allow HP WiFi printer to communicate

One would expect a new device would enable backwards compatibilty, ie, everything that connected to an XB6 would work on an XB7.

 

To make matters worse, comcast customer service are idiots.

I had spent about 6 hours trouble shooting the issue on my own, updating FW on the printer, connecting using WPS, connecting using USB, reseting the the printer to factory default, erasing all network settings.

I decided to call in to see if Comcast had any reports or informaton.  I asked to be connected to a network expert, having explained my HP printer would not communicate, but it was connected.

I also explained all my steps.

Guess what the first thing they did.... they remotely restarted my Gateway without telling me.  As everyone knows, we are all working from home.  My wife was on a Zoom conference call with her comapany and she was cut off becuse the Comcast agents first step is to reset the Gateway.  Then they ask me if the printer is now connected - duh!.

I tried to explain that they should never do a remote reset without informing the customer first.

Yeeeesh I just spent 3 hours working on trying to get my HP CP1525nw printer to connect to the XB7. Should've checked here first.

Re: XB7 Gateway will not allow HP WiFi printer to communicate

For what it's worth - I struggled with this for a full day (including a not helpful call with Xfinity tech support).  I seem to have found a workaround: the HP wireless laserjet has its own WiFi signal.  While it says it's connected to the XB7 Gateway, it won't print through that.  But, if on your laptop or smartphone you switch that devices Wifi from the XB7 wifi to the wifi of the printer, you can then send your print job to the printer and (at least for now) it seems to work.  Then you can switch your device back to the XB7 based Wifi.  A bit of a pain but better than having to buy a new printer...

Re: XB7 Gateway will not allow HP WiFi printer to communicate

Thanks - I actually jsut wired it via ethernet and let the XB7 handle the conection to the printer.  so if it is close enough to the XB7 or a pod, this seems to work.  At least at the printers new home.  🙂

Re: XB7 Gateway will not allow HP WiFi printer to communicate

The new gateway has an advanced security setting that is enabled as a default. Try to go into your xfi account or app and disable that security setting. Restart the gateway and try to set up the printer wirelessly.
