Hi. I'm having trouble with this for several days. Please help. We are in a small business running 30 workstations connected to a Win 2K Adv. Server with DHCP enabled. We don't host a website. it's just a server to handle normal business jobs. We have Linksys BEFSR11 router, hubs, and a dsl modem. We used to have verizon dynamic dsl, but are trying to upgrade it to a static IP address. Current settings in TCP/IP, which is working fine, is as following(It is not set to get an automatic IP): IP: 192.168.1.100 Subnet:255.255.255.0 Gateway: 192.168.1.1 DNS 1: 192.168.1.1 To change to a static IP, I changed TCP/IP settings like this(I got them from verizon): IP: 66.124.13.45 Subnet: 255.255.255.240 Gateway: 66.124.13.41 Then, I went to a router setting page, and changed the settings as above. Still, I can't get an internet connection, and a weird thing is the internal network is not working either. I had to set it back to the previous settings, but I need to reset it to the new one. How should I do it? Thanks for your help.

Looks like the Gateway should be set to the routers IP.

No. The internal IP address would not change. The 192.168 address would all stay the same. The gateway would be set to the IP of the router, but the router will have to addresses (or more). It will have an IP for the internal network, probably 192.168.0.1, and an IP for the external network - probably 66.124.13.41. With a subnet mask of 255.255.255.240 you are probably assigned several valid IP addresses. Like about 14 of them. This depends on the router and whether it is doing network address translation ( NAT). T Try leaving the internal IPs like they were with the 192.168.0 addresses and only change the external interface. That should work for you. Verizon should have given all the setup info this.

Glen is right, IP: 66.124.13.45 Subnet: 255.255.255.240 Gateway: 66.124.13.41 This is your public ip address and is for the WAN port on your router. Follow your ISP's instructions on PPPOE (usually for DSL). You can still use DHCP for the internal side of the network, just enable the router to enable the DHCP server on the LAN side. Everything should work like before except your public ip won't change, but since your not running a web server I don't see why it would matter either way.
