I agree with tangman... I am wondering if it's your router setup that's the problem, because the iphone supports B and G networking, and so if you have a B, G, or N router, the iphone should be able to communicate with it, since N is backwards compatible to B and G.
However, you can do what you are trying to do. Without getting some background info from you, my description of this process is going to be 10 pages long, and though I know everyone here is used to my 10 page posts, I'm not up for it this morning. Here are my abbreviated instructions:
1. Locate an available IP on your network (this is what I need more info for).
2. Connect a PC to your old router's LAN port, and get into the web management for the router.
3. Disable DHCP on the old router, disable any WAN functionality, and give it the unique IP address found in step 1.
4. Connect one of the LAN ports on your OLD router to one of the LAN ports on your NEW router using a crossover cable
That's basically it. It's really not that complicated if we can find out some background info first.
Open a command prompt on your computer (I assume it's connecting through your new router). Run the command "ipconfig" and look for a section of information containing IP addresses that start with 192. Post back the information from the IP ADDRESS and DEFAULT GATEWAY sections and we'll see what we can do.
But I'd really recommend figuring out why the iphone won't connect to the new router before you go rigging up this solution. Tell me... what is the make and model number of your currently in use (new) router? Do you use any security on your network?
