Recommend a good router/modem combo please

My Nighthawk has worked flawlessly for a couple years. I put Bitdefender on it (sans the VPN) and other than blocking an attack by my trail camera (my doing) the Bitdefender runs without issue.

A speed test shows I get better than advertised upload and download speeds.

But if you are going new get the latest and greatest. Spend the extra $$$ to go overkill. 
And be sure it is compatible with your service providers signal.  

If you live in a fairly large metropolitan area, you will find many routers for sale at cheap price. I got an Orbi router plus mesh satellite unit for $150.

Music streaming usually uses the UPnP protocol. For it to work well, you want to turn "IGMP snooping" off in the router settings. Orbi lets you do this; the TP-Link routers I've seen do not give you the setting and do not document whether the firmware has it on or off.

FWIW, I will be placing my Network Acoustics Eno streaming System filter and cable on USAM next week. It will be at a bargain price,  IM me for details. I am the original owner bought from a authorized dealer. I have something new coming next week to try.
