Thank you for your useful comments on this problem. From what you
mentioned, I can see it suggests, at least, two problems that
contribute to the failure connection.
1) The adapter that should be shared is the D-Link card; and
2) It is a PPPoE type of connection.
For 1), I've changed accordingly and after that it shows at least some
sign of connectivity (instead of not connecting at all before change).
The way I can see the connectivity is when I ping the default gateway
on the client (Windows ME) machine, it shows

However, I can have no way to load ANY internet page at all. If I ping
www.yahoo.com, for example, it shows
Unknown host
www.yahoo.com
after about 10 seconds of waiting. That makes me suspect the problem
is caused by PPPoE. Someting related to the max MTU setting. When I
did a

and 1470 is the best number I can achieve so far. I also noticed that
this number (1470) is not a fixed number but varied every time I
restart my client machine. In the worst case, it dropped to somewhere
below 1440. I've also tried to manually regedit
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans\0002
by adding MaxMTU=1470.
But it doesn't seem to solve the problem. I still cannot access any
web page. Any idea whatelse can I try further in order to rectify the
problem? Or, can somebody confirm to me, in this case, the whole
problem came from PPPoE? Thank you.
