Are both wired and wireless enabled?  Your original posting
doesn't
show any records for eth0.  In the 'slow' state, what is the
output of
'ifconfig -a' and route?

Hi Richard!
Here are three cases.

I apologize for my error.
However....

Case #1 - Cold boot, only wire enabled
--------------------------------------
(without CONFIG_NET_IPGRE)
net.eth0 in default runlevel.

NB: route and ping www.google.com are fast.

Case #2 - Cold boot, only wireless enabled
------------------------------------------
net.eth0 deleted from default runlevel.
After modprobe ndiswrapper and /etc/init.d/net.wlan0 start:
