R6400 - Random 'Page cannot be displayed' since Firmware update
Ever since I did a firmware update to my R6400 router, I'm getting random 'Page cannot be displayed' on different websites, no pattern.
I tried it on other PC's in the house and i'm getting the same problem. It also happens when I try to enter the router. After it says page cannot be displayed, I click retry, sometimes once or sometimes I have to click retry multiple times, then finally it goes to the website.
I never had this issue before the firmware update. Here is my setup. I have a comcast gateway with wifi turned off and my R6400 connected to it with 2.4 & 5ghz. As a test, I turned on the wifi on the comcast gateway and when I connected to it I did not have any issues.
I also have AT&T and when I use their gateway I do not have this issue. So everything is pointing to the Netgear router since the firmware update. Please help me figure this out. Thanks !!

a couple things.
1. any time theres an issue after a firmware upgrade, I usually recommend a factory reset and then a clean install. by clean I mean don't use a backup configuration for the install.
2. Turning off the wifi doesn't disable the ISP's gateway's routing functions. It can still causes a double nat.

Have you tried the R6400 in access point mode?
- VinnnyTutorI'm not sure it's a configuration issue only because I have this setup for 2 years without any issues until I just updated the firmware. The first thing I will do is a reset to factory. I will also check if the Comcast gateway will go into bridge mode. Thanks.

Here's an update
I tried factory reset but the problem still occured. I was able to find previous versions of the firmware, so I tried the one under the latest since I don't know which one I originally had.
I had to go 2 down (R6400-V1.0.1.68_1.0.43) to finally solve the issue. No more 'page cannot be displayed'. Does anyone know what date that version came out ?
