I am not an expert in computer neworks, but I thought that I know enough to diagnose most basic problems. But this problem leaves me completely stumped.
When I am connected to my home Wi-Fi, my ability to actually surf the web comes and goes randomly. About half the time when I try to open a new website, I get an error about my internet connectivity (DNS_PROBE_FINISHED_NO_INTERNET in chrome, The DNS name does not exist in edge). However, I am still connected to the internet - for example, I can continue chatting using Facebook messenger or WhatsApp web client.
This sounds like a DNS problem, except when my ability to surf is "gone" I cannot even enter a website using its IP address. In fact, I cannot even reach my router's configuration page (which again, I am trying to reach using its IP address - 10.0.0.138). A few minutes later the problem will resolve itself and everything will work fine, a few minutes later the problem will return and so on.
So if the problem is not with my Wi-Fi connection to the router or with the router connection to the internet (as I can use messenger), not in the DNS sever, not in the browser (as I tried both chrome and edge), where else can the problem be? What should I try to diagnose it?
If it matters, I am using Windows 10.
