Wifi vs Wired network debugging

If wifi can ping wired, but wired cant ping wifi - why?

Check the firewall settings on the Wi-Fi device and ensure that it allows incoming ICMP echo requests

To allow ICMP through firewalld:

sudo firewall-cmd --permanent --add-icmp-block-inversion
sudo firewall-cmd --reload

Also, worth checking nmcli device show

Other debugging options (last resort):

  • turn off Selinux sudo setenforce 0
  • turn off firewall temporarily sudo systemctl stop firewalld
