I have a Windows 7 machine on a home network that is reporting the "More than one device is performing Network Addressing Translation" error. The home network is both wired and wireless. The router is a Linksys WRT54G connected to a Smart Stream 5100 DSL modem. Both have the latest firmware. The modem connects to an AT&T/Yahoo ISP.
There are two computers connected on wired connections and various laptops connect at various times over the wireless circuit. The Windows 7 machine cannot see the other machines on the network, nor can they see the Win7 machine but they can all see each other. Other than that, everything seems to work OK. I do not have a Home Group set up on the Win7 machine because none of the other computers are Win7. I use them for testing software on different OS’s and different versions of Microsoft Office.
When I first installed Win7 the machine connected to all the other machines just fine. I’m not sure what changed to cause this problem but right now I have to use a USB drive to move data form/to the Win7 machine and it’s a pain.
I have researched the problem on the internet but the only solution I saw that looked promising was to download 3rd party firmware for the router and go through a long, drawn out process to get the router into bridge mode which I didn’t fully understand. I’m not a network engineer but it doesn’t seem reasonable to need that level of knowledge to set up a home network. I’m leery of the 3rd party router firmware and haven’t found any way to determine exactly which devices are performing the NAT functions so I don’t really have a grasp of where the problem is other than there is more than one.
The Win7 and other machines are set up to be DHCP clients and the router is set up to be a DHCP server. The router and LAN machines are on 192.169.1.x and the modem is 192.168.0.1 so they aren’t on the same network. The ISP assigns a DHCP address to the modem but since they aren’t on the same network I don’t see how that is causing the problem.
I tried a repair install but it didn’t change anything. I’m not averse to buying a new router but I’m not sure that will correct the problem. I don’t want to spend the money and then still have the same problem. Any help or advice will be greatly appreciated.
