View Full Version : I cannot ping either of my F12 laptops but can access internet from them

Hoping for help here.

Firewall disabled.
Static IP addys given to each laptop, but makes no diff when dhcp derived IP addys.
using wlan
Cannot ping either laptop from a windows box, bit windows box pings other computers

Can access internet from either laptop and Samba works too.

I can ping one laptop if I plug the LAN wire into it. In fact I can ping either the wlan IP addy or the LAN addy this way. WHen I remove the Lan wire I can still ping the wlan on the laptop, but restarting screws it all up again.

I see that iptables and other files change when I plug the LAN cvable in and then remove it again.

What can the fault be?

no fault

you could have an iptables rule on the laptops that restricts icmp replies out the wlan

or you have a setting in /etc/sysctl.conf that disables icmp replies ...

your netmask could be different on the laptops than on your windows box , so a broadcast ping will not reach them...

there could be many reasons . ...... hope this helps you find one
