WLAN clients cannot ping each other
Posted: Sat May 24, 2025 4:23 pm
This topic has been addressed already but I haven't been able to solve it.
I have the Openwrt router with 2 AP's running in the same network address family. The router has a static IP that ends in 1. The AP's end in 2 and 3, static addresses also.
The DHCP server is set to send addresses from x.x.x.100 to x.x.x.150. I have all my known clients with static IP's.
I became aware of this problem when I needed to print a document after my router replacement. I cannot ping my printer if both clients (Laptop and printer) are connected to the wireless network from the router. It happens only in this case.
I know know that it happens with every client that when connected to the WLAN of the router.
"From x.x.x.x icmp_seq=6 Destination Host Unreachable"
I have tried the "isolation" setting. The hairpin of the phy0-ap0 becomes "1" after reboot, but I have tried to put it to "0" with no success.
My expertise is not networking. I consider myself mostly self taught in the matter. This issue is making my head spin. Help will be very appreciated.
Best regards
