Slow speed

Despite the router being new it appears it may be using older or end of life technology as how it's not establishing a gigabit link to the modem.  Can you try bypassing the router and testing your speeds again to see if that makes a difference?  Note you'll need a paper clip or some similar small pointed device to push the reset button on the modem after connecting a PC for it to work.

The WNR2000 does have it's limitations.  I'd suggest trying without and see what your speeds look like.

Thanks for your help, I can get 48 to 55 MBPS connected direct but that will go way down to less than 20 MBPS many times.

Working with laptops so hard wire is not a option at this time.

Thank You

Indeed this isn't intended by any means to be a solution but it does confirm for us that it might be time for a router upgrade.  I'd suggest looking at routers that support gigabit Ethernet connections and preferably wireless-AC if that is within your budget.
