Right, without the PPPoE disabled the modem operates in a half-bridged mode (essentially it is a router running dhcp and 1:1 NAT). I would disable NAT, dhcp and PPPoE on the modem so that it is in fully-bridged mode and then see if the problem is resolved. Your symptoms are typical of a half-bridged router and a dynamic IP address from the ISP. Usually, the client on the LAN does not know when the ISP's WAN side IP address has changed and will not pick up the new address until the dhcp lease on the client has expired. To overcome this botched implementation the half-bridged modem has a short lease. This doesn't always work, as I suspect is the case here. HTH. -- Regards, Mick
