Static config
DHCP is superior to Static IP in every conceivable way. It is not any slower. However, when you FIRST connect to a dynamic ip router, your computer and the router have to handshake a bit, which takes a few seconds.
After that, they are at the identical speed. DHCP shields you from all sorts of trouble like colliding IP addresses, DNS server, subnet masks and gateways. It is way better and more reliable to go with DHCP.
Static ip is only useful if you *need* static ip, e.g. if you want to host a server on your router and you need the computer's dns server to stay the same.
That said, if you still want to use a static ip, here's how:
Simply disable the DHCP server in the router's settings. Also, go into the router's "status" page and take note of the DNS ADDRESS(S). You will need this later.
(Please note, if you disable the dhcp server, the only way to get back into your router and re-enable it is to use static ip on the computer, or to hard reset the router)
Then, you configure each computer connected to the router to use a static IP as opposed to obtaining it automatically. To do this in windows XP:
Go to start->control panel->network connections
Right click on Local Area Connection and go to Properties
Select "Internet Protocol (TCP/IP)" from the listbox
Click Properties
In the general tab, tick the radio box "Use the following IP address"
Type in the ip adderss you want (e.g. 192.168.0.105)
Type in 255.255.255.0 as the subnet mask
Leave the default gateway blank
Type the ip address of the DNS server you took note of earlier into the "Preferred DNS" section at the bottom of the form.
Click ok and ok and ok until you're out of all the boxes. Your IP is now static, and cross your fingers. If you did everything correct, it will work. If not, check your settings.
