Too frequently, there is a 10 to 50 second delay (usually nearer the lower end) between when I tell my browser (which is what I use most) to open a web page (usually in a new tab) and when the browser actually shows anything. If you’re using any kind of firewall software or hardware, it may be configured to be overly aggressive, blocking legitimate traffic along with potentially malicious traffic.

Some are not implemented very well and can see your own normal browser traffic as an attack, killing connections. See if your router has any kind of “intrusion detection” features you can turn off or reconfigure. If this works, you can investigate further to figure out why your previous configuration isn’t working. If you’re using your ISP’s server, try using a third-party one like Cloudflare (1.1.1.1) or Google (8.8.8.8). If you’re running your own DNS server, try using the one your ISP provides. If your primary DNS server is unavailable or acting flaky, then you might be seeing timeouts while your browser waits for a response, fails to get one, and then tries your secondary server.

In the absence of any other information, I would start by checking:ĭNS servers.
