RAX50 doesn't accept any port value in the Outgoing Mail Server Port Number field

The router rebooted as part of the firmware update process, so "step 1: reboot the device" cannot be a solution.

This feature has been in Orbi routers forever, so it is hard to conceive that Netgear has botched the code on this single router. "step 2: Factory Reset" may be the only recourse.

Because Factory Reset takes me over two hours of tedious data entry, especially considering the number of typos I make, it often helps to do a "soft reset".  i.e.:

• Back up the router configuration to a computer.
• Do the Factory Reset by sticking the end of a paperclip into the little hole and holding it for 15 seconds.
• When the router reboots, log in and begin the configuration proess.
• Do NOT set anything you don't have to.  Do not "register" the router.  Do not change the WiFi credentials. Do not sign up for Armor, Parental Controls, etc.
• Simply plow ahead until reaching a screen that offers a choice:
  o  Continue configuring manually, or
  o  Load a saved configuration
• Select Load a saved configuration and use the configuration that was saved to the computer.
• The router will reboot and "everything is back"
  (except, we hope, whatever garbage was causing the problem)

I have done the entire process in under 10 minutes.

If THIS doesn't fix it..... oh damn.
