    Snake the line. If no clean out access, remove the closest toilet.

    I've had luck with a rubber bladder which goes on the end of a garden hose. Get a bladder the right size for the pipe. You feed the hose into a cleanout in the basement. Feed it in as far as possible so there is not a lot of air between the bladder and the clog. Attach the hose to a faucet and turn on the water. The bladder expands to fit the pipe tightly and a small hole in the end of the bladder lets out water to put pressure on the clog.

    Here's an example:
