Hi, I have a network with two routers. One Zyxel connected to the internet (my ISP requires the Zyxel). A BEFW11S4 connected to the zyxel lan-to-lan and with DHCP disabled as the Zyxel takes care of that. Now - when connecting wireless to the BEFW11S4 there is no issue at all, but I have just tried to install a WRE54G expander, and it has been succesfully installed and I can connect to it, but then it's not possible to obtain an IP and I only have limited access to the network. Why is the expander screwing up the process of obtaining an IP ?
