How to change Nighthawk R7000 from PPPoE to DHCP Internet service provider

> [...] Model: R7000|AC1900 Smart WIFI Router

   Firmware version?  Connected to what?

> ISP [...] told me to change my router from PPPoE to DHCP.

   That's _all_ they told you?

   Knowing nothing, my guess would be that you need to change BASIC >
Internet : Does your Internet connection require a login? to "No".  And
then "Get Dynamically from ISP" in various places below.  Presumably,
your ISP would know if their new scheme does or does not use a user name
and password ("login").

   Alternatively, you could do a settings reset, and then let the
router's set-up wizard try to puzzle out the Internet settings at its
next start.  I'd save the current settings first, then reset, and, if
the wizard gets the connection to work, examine the BASIC > Internet
settings to see how it was done.  Then, if manually reconfiguring
everything would be a bother, restore the saved settings, and manually
make the appropriate changes to the BASIC > Internet settings.

> Under advanced Lan setup the DHCP box IS checked.

   ADVANCED > Setup > LAN Setup?  LAN is not where your problem lies.

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual (at least).  Read.  Look for
"Specify Your Internet Settings", "Return the Router to Its Factory
Default Settings", and "Manage the Router Configuration File".
