Getting older, not necessarily wiser!
In this post we will discuss converting an old router into a Wireless Access Point. In this case I used a NETGEAR WNDR3700v3 Wireless Dual Band N600 Router I picked up at a thrift shop for a buck US (literally).
Note: not an endorsement for NETGEAR, it just happened to be the router I used.
While this post is specific to the router I am using, I will endeavor to keep things generic enough that the process can be applied to most consumer routers. I like the N600 series NETGEAR routers because of no external antennas. They can easily be set on a shelf or hung on a wall and are not visually obtrusive. The router also has a built in four port switch which makes a few extra wired connections available.
I am assuming you have run already run a network cable from your Main router/switch to new location, power is available, and there is enough physical separation to make using the wireless Access Point (AP) practical.
I am also assuming you have done a factory reset on the router and know the default user/password/IP address login.
If you have not done so already, please review theses posts on routers and Access Points.
Your router should have two interfaces, most likely labeled WAN and LAN. The WAN interface is a single network jack, and depending on your router the LAN interface is probably four network jacks (builtin switch).
Your routers NAT service is located between the WAN and LAN interfaces. Since we are keeping everything on the LAN, we are not going to use the WAN interface or the builtin NAT.
By default most routers come with DHCP enabled. We want to use DHCP on our main router, so we will need to turn this service off.
Because we will probably need to access the router interface at some point, we also want it to have a Fixed static IP address.
The way this works is your wireless device tries to connect to your homemade AP, it forwards the request back to the main router, which determines a network IP address and sends it back to your homemade AP, which in turn sends it to your wireless device, establishing the connection.
This is similar to how the built in AP of your main router works, except on your main router it is built in and does not require a separate static IP address.
We have created a quick procedure for turning an old router into a Wireless Access Point (AP). It should work with most older routers you come across. As I stated the one I did this to I picked up in a thrift store.
This is a quick way to expand your Wifi Network to cover areas of your home where the signal is weak.
