7550, Can I add a WiFi extender?

[Ltcjc]

I live in rural NC and can only get AT&T DSL (phone line) internet service. My AT&T Netgear B90-7550025-15 modem/router has very weak WiFi for my large house. Can I get a WiFi extender to work with this Netgear 7550 device?  Thanks

   Why not?  Can you find an extender which prohibits that particular
modem+router, or which requires some property which it lacks?

   If you can run an Ethernet cable between the two gizmos, then I'd
expect configuring your "a WiFi extender" as a wireless access point to
provide the best performance.
