Upgrade from hAP ac2 to hAP ax3 AirPrint not Working

wgilthorpe · December 30, 2023, 4:21pm

I recently upgraded my main home router from the hAP ac2 to hAP ax3. I have been using ROS for a while, but I do not change settings very often, so I am by no means an expert.

I cannot figure out what I did differently in this config than the previous (upgraded about 6 mo ago).

On the old router, I would print from my iPhone no prob, but with the new router, my iPhone just gives no air print printers found.

I can print from computers just fine and my GF can print from her Samsung phone as well (after I manually put in the IP).

Both the iPhone and the printer are on the same network (wifi 2.4gHz limitation of the printer). Using the old router, it did not matter as both the 2.4gHz and the 5gHz are in the same bridge. For some reason, the AirPrint packets are getting filtered out somewhere (I assume).

I am not knowledgeable enough to know if this is an error in my config, or if this is a bug with the new ROS 7 (hAP ac2 ran ROS 6).

My config is posted below. Please note that this is just what I have cobbled together using the default config and trying to customize for my needs (and learn).

I have been reading on the forum, but have not seen any issues like mine (again makes me think I did something wrong).

I have seen tons of posts about the how the hAP ax3 has bad wifi, but my experience has been incredible, other than this small issue. I get the full bandwidth of my service (600mb) in rooms near the router. In the near future, I plan to add a cAP ax on the other side of the house.

Feel free to pick this apart and let me know what I have done incorrectly. Thanks in advance for any advice.

Though probably not the solution, I do notice some things:

Why did you add the Guest wifi (as it is part of the same bridge as the home network)? Aah, you added a bridge filter…
Why is the DHCP lease time set to 10 min? You probably want to change it to a couple of hours.
Are you using detect-internet? It has turned into some strange behavior, perhaps turn it off?
UPnP…mmm, not interested in security?

Sure both printer and client are conencted to the same (not guest) network?
Does the printer respond to ping?

erlinden,

Thanks for the quick reply.

Why did you add the Guest wifi (as it is part of the same bridge as the home network)? Aah, you added a bridge filter…

I followed a how-to on Youtube to isolate the Guest network

Why is the DHCP lease time set to 10 min? You probably want to change it to a couple of hours.

I guess that is default when using quick setup. I will change if that is best practice.

Are you using detect-internet? It has turned into some strange behavior, perhaps turn it off?

I am not using this. Not sure why that is enabled.

UPnP…mmm, not interested in security?

I enabled this trying to get the AirPrint to work. This was part of my troubleshooting. I will disable as it did not seem to make any difference.

Sure both printer and client are conencted to the same (not guest) network?

That was my first thought. I did verify this.

Does the printer respond to ping?

Sure, I can access the config page via the browser.

Thanks again. I will disable both the internet detect and the upnp. I will also up the DHCP time as suggested.
