Why does wifi keep disconnecting only on Ubuntu and only on a single wifi network?

I'm having problems with network connectivity on my Ubuntu 22 install on my laptop. I have a dual boot system with Windows 10 and Ubuntu 22.04. The problem is that when I visit some websites, they keep loading for a long time and then error out saying that it took too long to load the page. The strange thing is that I am able to visit popular websites just fine, e.g., google.com, youtube.com, reddit.com, etc. When this problem happens, I can't visit stackoverflow.com, slack messages don't load on the web/browser version,etc. I don't know how to debug this or how to solve this. It seems like a very niche and strange problem.

Also, this problem doesn't happen when I'm on Windows on the same laptop. It also doesn't happen when I'm on another wifi network. Another thing is that if I disconnect and reconnect wifi on Ubuntu, then it starts to work. But after a while, the same problem happens again.

Does anyone have any useful information about how to fix this?

I would use a certain DNS server like 1.1.1.1 on all cases and move the Wi-Fi AP to a less used channel ([this](https://askubuntu.com/a/1373700/349837) might help). Then `mtr` and `ping -f` might help too.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
