"192.168.1.1 didn’t send any data." Error when attempting to edit device in attached devices menu

   Which "the Netgear app"?

> Firmware: 1.3.2.134

   You might try a different/older version.  Recently there have been
complaints about editing on the Attached Devices page on multiple

models.

   Visit http://netgear.com/support , put in your model number, and look
for Downloads.  (For older versions, under Firmware and Software
Downloads, look for "View Previous Versions".)  Find the kit(s).
Download the kit(s) you want.  Read the "Release Notes" file for
instructions. (In the User Manual, look for "firmware", and,
especially, for a topic like "Manually Upload Firmware to the Router".)
When that fails because of a deficient User Manual, try:

   Netgear typically puts more effort into formal support requests
(warranty or paid) than complaints posted here.  Which is more annoying
when they break some existing feature, affecting post-warranty devices.

   Duh?  Read much?  Or just post the same old boilerplate, regardless?

   I don't see how.  Clearly, the web browser is talking to the
router's management web site (at the router's default LAN IP address).
