Not enough RJ45 ports? What to do?

We are out of RJ45 ports and need advice on what to do. We have Time Warner Cable with turbo that gives us about 50 Mb/s. We have the Time Warner Modem. From the Modem we have a RJ45 cable going into a Netgear Gigabit Router Duel Range WNDR3700 that has 6 ports on the back. Plugging in the Time Warner Modem, that leaves 5 ports left. We really would like at least 3 or 4 more ports. Five or six would be even better for future growth.

We want our home network to see everything else on the network (just one big network), but are not sure how to proceed. Cost is not really an issue. What are we missing?
 
Hi,
Add a small switch to benefit from additional ports. then plug computers, printers,... on the switch ports. You'll be able to have LAN connetivity and Internet connectivity. That's what I do in small deployments.
 
Thanks for the response. I just checked Microcenter for a switch. Would this work? Yes, 24 ports is overkill, but its only $99. Would I just run an RJ45 cable from this switch to my Netgear WNDR3700 Router and then plug in all my devices into the switch? Leaving the five ports in the router unused?

I purchased an unmanaged plug and play TP-Link 16 port Gigabit Switch at Microcenter for $66 model TL-SG1016D.

After I hooked everything up, I keep getting DUPLICATE IP ADDRESSES on Network 192. 168.1.1 on all my computers. How do you fix this?

Here is how I have things hooked up:
Time Warner Modem connected to Netgear WDN3700 Router, Router to this new TP-Link Switch - all computers, printers, TV's plugged into the switch. If I plug a computer directly into the Router, it works just fine. The switch seems to be causing the problem with duplicate IP Addresses.

I've reset all the equipment numerous times, but there is obviously something else wrong.

Any Network GURU's out there that have seen this before?
 
The first thing I would check is how large your DHCP range is. Make sure it is large enough to support the increased number of devices.

Being an unmanaged switch means it shouldn't modify anything DHCP related.

Also make sure you don't have any devices set to use a static IP inside your DHCP range.
 
You need to check all the computer's, printers and TV's and see if any of them have a static IP address. Plug things in one at a time to trouble shoot.

Also both devices may have up-link ports that need to be used. Using anything but the up-link port may cause problems.
