RAX200 AirPrint Intermittent

Config:  Nighthawk RAX200 with latest Firmware. ISP Router (192.168.x.x) with one connection to Nighthawk (10.0.0.x).  Nighthawk only has a couple of devices hardwired, all others are Wifi. ISP is 500/800 up/down on average.

 

I have a Canon MFC743cdw (latest firmware) on static IP / wifi off Nighthawk (10.0.0.74).  If I reboot my router, I can discover my Canon (Printer / Scanner) via AirPrint from Mac(s) and iPhones, great.  but after some period of time, sometimes hours, sometimes 24-48 hours, the AirPrint connectivity is no longer available.  I can connect via LPD to the printer but that doesn't help iPhone connectivity.  happens with two different printers and three different Macs.  Seems to be consistently working if I reboot the Nighthawk...  Any suggestions?

    Might help to fix your double nat.

    Cascading routers (with both in router mode) can cause issues. 

     

    Options? 

    1. Put the isp modem/router in passthrough/modem only mode. 

    2. Put the netgears IP address into the ISP router's dmz

    3. put the netgear in access point mode.
