Help! I have the same problem and it is giving me fits.
I can ping my BBB from my computer (Windows 8) [ping 192.168.7.2] just fine but cannot ping my computer from my BBB [ping 192.168.7.1]. I'm using the provided USB cable and have scoured the internet for help. Any idea what it could be?
After running ifconfig on the BBB:
eth0 Link encap:Ethernet HWaddr 7c:66:9d:55:a8:f1
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0
