Here is some detail about the problem I am having. I have a hard and
wireless LAN going to the same AP. I used the commands that you specified
and at first it seem like the wireless LAN started working. but as soon as I
disabled the hard LAN I could no longer ping anywhere. I have label each new
command with (***) and comments with (A1). Let me know what you think.
Thanks
After fresh reboot
