Wireless Access in Bay Ridge other than Starbucks.
Where in Bay Ridge (abouts) are you? I ask only because I live way down at the very end near the water, which would make spots in the 60s/70s a decent hike for me. That said, Omonia cafe/bakery (sp?) on Third Ave and 76th Street has -- I think -- free wireless. I was able to find nothing else (and I looked fairly thoroughly).
In the end, I had to suck it up and get Time Warner high speed modem. Day of defeat. Good luck, though! I hope somewhere new has started offering it.
