V1.0.4.122_10.0.95 Update on R6400v2 kills lon in page

michaelkenward...

Checked in this afternoon and saw your post. I am happy staying on V1.0.4.120_10.0.91 for now. After trying the Netgear reset method to get tftp to work several times and failing I tried to log in and got a log in prompt. This was after reseting the router about three times trying to get tftp to work. When I loggrd in I saw the router was at V1.0.4.120_10.0.95, but the web pages were kind of off and I had trouble navigating to the update page. So I reapplied V1.0.4.120_10.0.91 and reapplied my config settings I saved before the update. Now everything works as it should. As I said I am leary of the new update and plan to sit on the old version until the dust settles. I have put numerous updates on my older and this Netgear routers without any issues. As I said I noticed that the router was not showing the http/https ports open after the V1.0.4.120_10.0.95 upgrade, which would explain why you could not log on to the GUI as the web service for the GUI was not reachable. Any one that gets the error message I reference in my 2021-12-22 01:24 PM post above can try using nmap to see if ports 80 or 443 are open. Is easy to use and free on all platforms. A quick scan will tell you if the ports are there or not. It may help Netgear to know this if enough users see this problem. I don't know if it is an install issue or not but it seems others are gettin the same issue.

Here is an nmap scan I router and as you can see port 80 and 443 are there. They were not when the router was running the newer update (see my post at 2021-12-24 12:34 PM).

$ sudo nmap -T4 -F 192.168.1.1

michaelkenward I noticed your last post at https://community.netgear.com/t5/Nighthawk-WiFi-Routers/R6700v3-Firmware-update-V1-0-4-122-10-0-95-problem/td-p/2174695

ie - "OK. That adds up to enough cases to warrant escalating this."

Hope this helps...
