Can you connect a 2-wire DSL wireless modem router to a cable modem?

Not directly. To create a local wireless ethernet network connected to a cable modem a Wireless Ethernet Router Box (WERB) would be required. It connects to the Cable Modem (CM) using an ethernet cable.

If all you want is to have a local wireless ethernet network, the WERB would do that for you and you won't need to use the 2-Wire DSL wireless modem router.

The 2-Wire DSL wireless modem router really does the same as CM + WERB but for connection of local computers and peripherals to a 2-Wire DSL ISP instead of to a cable ISP.

Normally a cable modem connects to an ISP's cable network on one side and, on the other side, to either a single computer or to an ethernet router which could be either of the hard-wired "local cable" type or a "local wireless" type. The ethernet router then connects to several local computers or peripheral devices such as printers, scanners, etc.

A DSL wireless modem router connects to an ISP's 2-wire copper telephone line on one side and, on the other side, via a local wireless ethernet to several local computers or other peripherals such as printers, scanners, etc., each of which must have a local wireless ethernet connectivity device.

It is not clear from the question that you want to enable local computer users to connect reliably to either the ISP handled by the DSL wireless modem router or to the ISP handled by the cable modem. If that is what you want, then, if you are not already familiar with setting-up ethernet devices -- which may be the case as you asked this question here -- either get an ethernet router expert to help you or read the instructions that come with all modems and routers to find out what to do.
