Cannot Ping Server Despite UFW Inactive, Server Can Ping Other Devices

bb flag

I'm running Ubuntu Server 22.04.2 LTS on a computer on my home network, connected via wifi. It can connect to the internet, and can ping other devices like my main Windows PC and my phone just fine, however whenever I try to ping the server from my PC, the requests just timeout.

UFW is disabled on the server so the pings shouldn't be blocked. I've also tried it after enabling file and printer sharing on my main PC, and I even disabled Windows Defender, just in case the responses were being blocked for some reason.

I've checked at least a dozen times using ip a and ifconfig, and I'm confident the IP of the server is correct, I'm not using docker0, eno1, or lo, but rather wlp1s0, the wifi network adapter that gives a valid IP.

I'm at a loss for what the issue could be, so any help would be really appreciated.

Edit: SSH also times out, and Zenmap/Nmap traceroute shows that it is up, but doesn't give any further info.

I think you have "wi-fi" isolations in your router...check it and update us

While that wasn't the issue, your answer did get me thinking about the router side more. As it would turn out, my place has two different routers, and my PC and server were connected to different ones lmao. My PC has a wired connection that runs through walls, while my server was connected via WiFi, so while dumb, it wasn't an obvious error to spot, at least at my knowledge level. So thanks since it did help anyway haha.

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.
