After upgrade to 1.0.2.90 R7800 (X4S) does not open an http port.
Logged into the R7800. The GUI informed me that a firmware update was available. Using GUI downloaded and upgraded firmware from 1.0.2.62 to 1.0.2.90. Routing and WiFi are working, and the router ...
Do NOT user the TFTP method to upgrade the router. This is only for last resort.
First try the factory reset with the router and setup from scratch with a good browser and wired PC at 192.168.1.1.

A factory reset did not improve matters. While the router and WiFi still functioned, HTTP and the GUI were not functional.
A successful tftp upgrade to 1.0.2.90 did not improve matters either. The balky R7800 still does not expose the GUI.
If I were the supervising engineer or manager I would ask two questions at this point:
1. Was the upgrade to 1.0.2.90 regression-tested back to 1.0.2.62? (I suspect not.)
2. Were there any changes to the download or DFU code between '62 and '90? (Entirely possible.)
If so, what were they?
As I no longer have tech support on this product, I have no way of injecting these questions into Netgear tech support
and I am unlikely to get any answers. My best bet is to locate and load successively older firmware versions for this
router until I find one that works.
Thank you both for your timely and valuable advice.
A couple of thoughts to add to this discussion.
The term “Factory Default Reset” is a misnomer that is scattered far and wide on message boards and in OEM manuals. The recessed push button action does not return the router to factory default firmware. The action returns all settings to the default values established within the firmware that is currently installed (flashed) on the router. Something definitely got lost in translation.
I own an R7800 router and would not operate it for one hour without installation of Voxel’s firmware. Voxel takes the stock Netgear firmware and polishes it to where it works reliably. Start with the Read Me file on his web page: http://www.voxel-firmware.com/Downloads/Voxel/html/index.html. It is easy to go back to Netgear stock firmware from Voxell if you want.
As you have found out, the startup sequence and timing is critical to establish a connection between a modem and router. In particular when you change out one or the other.
When you save a configuration file for later use, be sure and rename the file to establish which version of firmware was in place when it was created. The configuration file for firmware version X-01 most likely is not compatible with the configuration file for firmware version X-02. Lots of headaches can be created by backloading a configuration file that was created with a different firmware version than is presently flashed on the router.
