无法ping通公网IPv4地址的问题排查求助

Hey everyone, I’m stuck with a frustrating issue where I can’t get a proper response when pinging my public IPv4 address. To rule out firewall interference, I’ve disabled both my Windows local firewall and my router’s firewall for testing purposes, but the problem still persists.

I’m really scratching my head over this—does anyone have any potential reasons or troubleshooting tips that could help me figure out what’s going on here?

Here’s some additional network details pulled from my machine:

IPv4 Address. . . . . . . . . . . : 192.168.1.8
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : fe80::1%19
                                    192.168.1.1
