Re: Nighthawk R6400 appears to be blocking some web sites

kn4hh · ‎2021-11-25

I have a AC 1750 R 6400 Ver 2 router connected to a Surfboard cable modem. I am running Windows 10. Just recently, I have not been able to log in to a number of web sites and applications that need to connect to the internet. On some sites if I click the browser refresh icon a number of times, the site will eventually load.

I removed the router from the modem and connected a pc directly to the modem and the problem goes away. I have logged in to the router and I do not see any firewall or blocking set.

I would appreciate any suggestions.

Netgear has set up a community forum specifically for General Router products. Most of the people who watch that forum are more likely to have experience with older routers and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:

Please use this link to the main forum product list to review and choose where to make your posts.

Model number for the modem?

There's a lot of them out there, some of them modem/routers.

What firmware do you have on the router.

Do the router's logs give any clues?

Is this question related to your earlier one?

PS Unless you have a hardware specific issue, for generic questions like this there really is no need to dive off into another section, where there are far fewer visitors. The main difference between your router and a Nighthawk router is probably the price.

I thought this might be related to my past problem. I was running Firmware version 1.0.4.120_10.0.91

I went back to version 1.0.4.118_10.0.90 and I still have web site blocking.

Here is the latest log entries.

So sorry for the delay in replying. I finally did a complete system reset and all web sites are now available. However, if I update to formware version 1.2.0.88, the problem returns. I ended up going back to the previous firmware version which cured the problem.

Thank you for the suggestions.
