New R7800 will not connect to Brother printer

I just bought a new Netgear R7800 this morning, and have been able to get everything set up and working except for my printer.

I currently use a Brother HL-2275DW using a wired ethernet cable into the router, and while it was working fine for my previous Asus router, on the Netgear it never fully connects. The router always shows the LAN port, whichever one I choose, as amber (never goes solid white), and the printer status on the comptuer shows as offline. 

I've tried restarting the router, the computer, and of course the printer, all with no success. 

I've deleted the printers from Windows and redownload the drivers, but when I go to install them it will not allow me to continue as it does not see a printer connected to the network.

So basically, I'm stuck and can't do much because the router seems to not be recognizing the printer. It does see it as an attached device, but will not fully connect to it.

Running Windows 10 by the way, with the Anniversary upodate.

Any help you guys could give would be most appreciated.
