ORBI RBK53 (AC3000) "No AirPrint Printers Found" After Firmware V2.1.4.10 Installed

[ZoneMaster]

Have been running my ORBI RBK53 system for almost a year. AirPrint from multiple iOS devices (1x iOS 9.3.5 & 3x iOS 11.3.1) worked flawlessly until a few days ago. The only thing that changed was the ORBI firmware, which is now at V2.1.4.10. Wi-Fi printing from iMac & Windows is still working but my two AirPrint printers (one HP & one Brother) are reported as "No AirPrint Printers Found".

I have performed the following troubleshooting:

1. Verified printer settings are unchanged
2. Performed network port scans
3. Rebooted ORBI network & printers numerous times
4. Factory reset of the OBRI units

I have observed the following:

1. There is NO discovery of AirPrint printers
2. I can still print via AirPrint if a printer was still listed as a previous printer
3. Rebooting printer may reenable AirPrint for a very short time
4. The network scan shows no Bonjour/Zeroconf services

It appears the latest ORBI firmware is suppressing AirPort discovery.

I have been running the 2.1.4.10 firmware since last week. Network scan via "Net Analyser" iOS app showed NO Bonjour flags present

I have performed the following additional toubleshooting from my iMac (which is fairly distant from my Comcast/ORBI gateways):

1. Connect ONLY via my Comcast Wifi Modem:
   1. Powered off ALL ORBI units:
   2. Turned on WiFi on my Comcast Router
   3. Logged in to my Comcast WiFi
   4. Weak signal & slow upload/download speeds
   5. mDNS/Bonjour/AirPrint was rock solid
   6. Network scan via "Net Analyser" iOS app shows Bonjour flags are present
2. Connect ONLY via ORBI RBK53:
   1. Turned off WiFi on my Comcast Router
   2. Powered on ORBI RBR50 Router
      1. Logged into ORBI WiFi 
      2. Better signal & faster (but not max) upload/download speeds
      3. mDNS/Bonjour/AirPrint working. Network scan via "Net Analyser" iOS app shows:
         1. macOS & iOS seem to reliantly report Bonjour as present
         2. AirPrint printers (HP & Brother) sometimes don't report Bonjour as present
      4. Waited
   3. Powered on ORBI RBS50 Satelite closest to my iMac
      1. Max signal & max upload/download speeds
      2. mDNS/Bonjour/AirPrint working
      3. Waited
   4. Powered on final ORBI RBS50 Satelite
      
      1. Everything working
      2. Waited

While mDNS/Bonjour/AirPrint is still sometimes glitchy. It is working under the 2.1.4.10 firmware after starting the router & satellites in slow sequence.

What FW version was it working on? 

Try a factory reset and set up from scratch.

[ZoneMaster]

Don't know firmware version prior to update, only that I have never had problems before afew days ago. I have rebooted ORBIs numerous times & performed factory resets/new system config at least 3x.

Something you might want to contact NG support about and ask for help with. Might need to revert to prior working FW.

How do I contact NG without a paid support contract?

i have a rbk20 and this issue popped up after upgrade from 2.0 to 2.1.4.10.  I ended up disabling MUMO, Fast Roaming and Beam Forming to fix the AirPrint issue.  I don't know if all or just one option is the cause but I have no patience at this time to further troubleshoot.

BTW: NG's "90 day & then you pay" support is terrible! Heck, Apple (which so many love to compain about) still lets you contact them after 90 days & has a knowledge base for questions & error reports. NG has a paywall & community support!
