Nighthawk X6 AC3200 Smart WiFi Router (R8000) DNS ISSUE
My router firmware version is: V1.0.4.84_10.1.84
I am having intermittent issues with DNS. I see this in a web browser. When I first go to a site it displays not available. but then a couple of seconds later it displays. It appears the first failure is because of a site not found error. For sites I go to frequently they always come up quickly. My dns server for my windows 11 desktop is my Netgear Nighthawk X6 AC3200 Smart WiFi Router (R8000). IPCONFIG /ALL show "DNS Servers: 192.168.1.1" My desktop is direct wired to it. I have tried 2 different DNS settings on the router, but it seems to make no difference. 1 is to get automatically from ISP, and the other is to manually set 8.8.8.8 and 8.8.8.4.
Using Fiddler to try to understand this. First time I try to browse to dji.com...
GET http://dji.com/ HTTP/1.1 Host: dji.com Proxy-Connection: keep-alive Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7 Accept-Encoding: gzip, deflate Accept-Language: en-US,en;q=0.9
The response is...
HTTP/1.1 502 Fiddler - DNS Lookup Failed Date: Fri, 09 Jun 2023 15:48:57 GMT Content-Type: text/html; charset=UTF-8 Connection: close Cache-Control: no-cache, must-revalidate Timestamp: 08:48:57.535
[Fiddler] DNS Lookup for "dji.com" failed. System.Net.Sockets.SocketException No such host is known
Then I immediately browse to dji.com again, and it connects completely without issue.
I am highly suspicious of the DNS provided by my router in this.
FWIW - This is my home computer, not on a domain, but rather a workgroup.
What may be causing this intermittent issue, how can I diagnose it, and more importantly how can I fix it?
