Not sure is that the best basic settings I've done.
Hope anyone can help me tweak a little to make it much better.
I'm confuse on the dhcp both are enable at the moment.
Below is the vigor 120 settings

only ticked that PPPOE-Pass-through. Username & password is greyout.

The DHCP just leave it as default & the rest of the vigor settings are default.
WR941ND (Gargoyle)

which the lan dhcp enable too.
Thanks
