I have a question. I currently am using a Belkin Wireless N Router for my DSL wireless network, but is it possible to hook up another modem to another DSL and buy a D-link gaming wireless N router and bridge the two routers. This would give an option to choose two different networks but also set a stronger signal if its possible to bridge two different brands. Any suggestions??

Both routers need to support bridging. Typically this is done with one router and one Access Point. It is typically a good idea not to mix brands. You won't need another modem. If you want separate networks (no idea why) you would need to use different subnets and a different subnet mask.

I see. Thanks for the advice. The reason I was wanting to was in case of one network failure which probably never happens, but it was an idea.

This is known as "redundancy" and is typically only done when you have two ISPs or a redundant line from your ISP. In that case you would want a dual WAN router.
