Can I have a cable modem AND a DSL modem on one home network?

My cable modem is speedy, but the service has too much downtime, so I also ordered DSL.  Is there some way I can use both modems to increase bandwidth, or at least to automatically switch over when one goes down?

If you search for "dual WAN router," you can find a number of options. Unfortunately, most of them are pricey. Hawking sells one for under $100, but CompUSA's listing includes a scathing user review. Others listed in a Network World review ( are $500 and up, though the review is 18 months old and a quick check with Froogle indicates that prices have come down somewhat.

You would need a dual broadband router or a second router and then manually switch between the two using a ROUTE command.

Do you know any manufacturers of dual broadband routers?  I can't find any.
Sorry for being so un-knowlegable, but what's a ROUTE command?

TCP/IP is routed over the internet.  I have two systems at home acting as routers.  When I want to use cable, I alter my default gateway/default route to the internet.  Normally, it's , but to use cable, I use by issuing the command:

I think your question was is there a way to INCREASE bandwidth using 2 sources, not switch between the two --- using a different gateway/route... am I wrong?

to do that you will need a router capable of load balancing..

Also ... remember the basic limitation of dual WAN links.  Each individual transaction (page retrieval, image on that page, etc.) will only follow ONE of the paths.

So while you get some benefits from parallelism (two image files really can be retrieved simultaneously), it will not help large transfers.
