So I just got DSL, but I still have my cable internet active for a few more days. I connect to the DSL wirelessly, and was wondering if there were a way to use both connections at once (perhaps connect cable to computer via ethernet). Would I get addtional speed, or would the computer use one over the other?

One at a time unless you have an aggregation router and even then, each connection can only be handled by one of the connections. You will never get a connection at the combined speeds/capacity of both pipes.

You can use both links simultaneously, but only by statically routing some traffic over one connection, leaving all other traffic to use the default route through the other router.

For example, assuming your DSL router is at and your Cable router is at, you can set your Mac's default route to (the DSL line) and tell the system to manually route specific subnet's over the cable modem via the route command:

route add -net netmask

This command will route everything for through the cable router.

Of course, the trick is knowing which traffic is best suited by each connection. There are routers that can handle that via BGP, but I don't know of any home router that can handle that.
