Help with D-Link Router Setup

Need help in setting up a wireless router.

Router: DLink WBR-2310
Mac: Intel 2.5 - MacOS 10.5.2
Modem: Comast Highspeed

Friend suggested this was a good router to get but can't figure how to setup. Is this a big waste of time or is there an easy fix.

Please advise,
Thanks.

Read the manual.

Watch the video here.

The basics are...
Plug the router into the modem.
Plug the Mac in via an ethernet cable.
The router will have a default address, likely 192.168.1.1 or 192.168.1.0.
Open Safari, and type http://192.168.1.1 and the router should come up.
The manual will tell you the default password and username if there is one.

Once into the router, you have do some setup depending on if you are using the wireless or not. What security options to use. Also you may need to setup you Mac to use DHCP which it likely already is unless you changed it.
