I buy a WRVS4400N router. Setup to surf internet successfully.
But each client can't ping, samba, file sharing to each connect to WRVS4400N.
In the router admin page. We can see each client connect to the router.
I have one SSID only. And setup the
Wireless Isolation (between SSID w/o VLAN)
and
Wireless Isolation (within SSID)
both to disable.
And have reboot it several times.
