I'm trying to setup a static IP on my desktop PC so I can set up port forwarding to run a Ventrilo server. I successfully set up the static IP but the laptop that connects to my wireless network couldn't get online at that point.

My internet is through DSL. It comes into a Efficient Speedstream 5100 which then goes into a Netgear WNDR3400v2 wireless router. My desktop PC is then connected to that with a Cat 5 and my wife's laptop connects to the wireless. This may not be the best way to do the system but it's what I figured out.

My question is, how do I set up the static IP and still have the laptop connecting? Did I mess something up in the wireless when I changed the IP to static? Or should I just set up a static IP on both computers? It seems that if I set up a static IP on my desktop that shouldn't mess up the connection of the wireless through the router and modem but maybe it does.

All help is appreciated.

How have you assigned the static IP? Have you disabled DHCP on the router? I'm assuming your wifes laptop is getting a 'limited or no connection' error?

Basically the best way to do it with a home router is to go to the LAN DHCP settings, make sure it is enabled. There should then be a bit for DHCP reservations. From there you reserve an IP address specifically for your PC using your PCs MAC address.

I've just copied the below from the manual, should guide you through it - http://www.downloads.netgear.com/files/GDC/WNDR3400V2/WNDR3400v2_UM_03APR2012.pdf

Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it accesses the router’s DHCP server. Reserved IP
addresses should be assigned to computers or servers that require permanent IP settings.
 To reserve an IP address:
1. In the Address Reservation section of the screen, click the Add button.
2. In the IP Address field, type the IP address to assign to the computer or server. (Choose an
IP address from the router’s LAN subnet, such as 192.168.1.x.)
3. Type the MAC address of the computer or server.
Tip: If the computer is already on your network, you can copy its MAC
address from the Attached Devices screen and paste it here.
4. Click Apply to enter the reserved address into the table.
The reserved address is not assigned until the next time the computer contacts the
router’s DHCP server. Reboot the computer or access its IP configuration and force a
DHCP release and renew.
To edit or delete a reserved address entry, select the radio button next to the reserved
address you want to edit or delete. Then click Edit or Delete.

I have to admit I don't know what some of this stuff means. Every time I believe I've figured out addresses I learn of a new one! I appreciate the information and I think it will help, I simply need to wade through a bit more learning.

Initially I set up the static IP using a walkthrough associated with the Mumble wiki I believe. It had me check my IP, subnet mask, default gateway, and the DNS servers and then change my internet settings on my PC to use a static IP which I created and the same subnet, gateway, and DNS servers. It technically worked but only in the sense that my desktop remained online.

So what you are saying is that I can basically leave my PC and my wife's laptop settings alone and go into the router to specify a specific IP address ONLY for my desktop PC and that will keep it static while assigning her's like usual? That sounds logical. Can I find the MAC address in the ipconfig? It looks as though it is listed there.

I also had a friend suggest that I don't need to set up a static IP but simply look up my actual IP address that the rest of the world would see by going to www.canuseeme.org and using that IP for my Ventrilo server. Do you know if this is possible?

Thanks again for all the help.

Essentially with DHCP you can have it assign different addresses each time, or you can create reservations for certain MAC addresses, which ever you choose can be done on a host by host basis. So, yes you are correct with paragraph 3. Yes, you can find your MAC address by typing ipconfig /all into a command prompt. It should be listed as:

Physical Address. . . . . . . . . : BC-5F-F4-59-C9-F9

Leave everything else on both machines as normal and you should be good to go.

Your friend is kind of right, basically, that is what you are trying to do. If you assume that your internet/outside/WAN address 207.56.98.27 and you were forwarding port 8080, and you are trying to get to a web based management page. You would simply open IE go to 207.56.98.27:8080 and it will follow the port forwarding to your device. Essentially, everything on your network is seen as that same single address on your router.

Also, something you may want to consider is using a Dynamic DNS service. Because your ISP will change your outside IP address of your router from time to time. Netgear routers are compatible with it. But, one bit at a time.
