One of the wireless networks I use has a class B public network with a 6 bit network mask. The Vibrant ignores the net mask and tries to connect to anything on the whole class B directly, instead of using the gateway. As far as I can tell it does get the correct subnet mask from dhcp, but doesn't use it. I'm using the ifconfig app from the market to see what subnet mask it got, and it is the 6 bit mask. Has anyone seen this?
