I am using a DLink DI-624 on the LAN as an access point. DHCP is disabled, the WAN port is disconnected, DNS forwarding is enabled. I have the DLink’s IP set in the static table (DHCP configuration.) After a period of inactivity, I am unable to get beyond the DLink. I cannot ping the ZS box from a wireless client. I can connect to the AP, and using the DLink’s built-in ping utility, I can ping the ZS box LAN interface as well as external hosts. If I connect the PC to the wired LAN and then disconnect, I am able to regain wirelesss connectivity. Anyone else experience a similar problem?
