Before we move on, we need to change our router's WAN (Internet) connection IP type.
Generally speaking, if you had DSL before, your WAN type would be PPPoE that requires an user name and a password; On the other hand if you had Cable before, your WAN type would be Dynamic IP (DHCP-Assigned).
If you had Cable, or your current WAN type is on Dynamic IP (DHCP-Assigned), then you are good to move on. Might just well double check before you move on so we don't get confused.
If you had DSL, or your current WAN type is PPPoE, you might want to change your WAN type to Dynamic IP (DHCP-Assigned), refer to your router's manual to change it.
Like mentioned before, this method provides most flexibility and preserves all your previous settings including your wireless network and firewall settings. So you don't have to completely abandon your investment and manually enter all your settings into the RG.
Advantages: Preserves all your existing settings; Not limited to a 802.11g network infrastructure if you have a better wireless router/AP; Provides flexibility.
Disadvantages: Can be troublesome for beginners; requires some knowledge of networking.
Let's get started. First off all, let's take a look at the back of the RG (not to scale):
Also let's look at the back of the wireless router. Note: this is just an example to represent MOST of the wireless routers in the markets right now. Most of them look identical in terms of connectivity they provide.
You don't have to turn them off during this process. However after certain steps you might need to power down and up the wireless router to refresh the settings. Of course it's just an suggestion, you don't have to.
In my case, I have the TV set-top box connected to the RG. As you can see here, it showed both my wireless router and the set-top box. However the set-top box is in IP form and my wireless router is in the NetBIOS name form.
You need to figure out which one is your wireless router. By default, the new wireless routers will have it is model name listed in the "Local Devices" since RG is smart enough to learn it. Of course, if you know your current computer's name or IP address, you can easily figure out which one is the wireless router.
If you click on "View Details", it will show a more detailed page about the change. Again, do double check if the "Device" is your wireless router.
