So I've been running Netgear R7000 since 2014 and about 2 years ago moved into a bigger place around 3000 sqt. While the coverage is not bad and speed is good, my office in downstair suffers lag and signal lost at times. I already have hard able running to the computer so it's my phone wifi that I am trying to solve at the moment. My router is centered on my 2nd floor. Pretty much cover 90% of the house. I did purchase some wifi extender, but it requires me to create another ssid which is a problem when I walk around the house. Is there any product that would give a bigger boost in the signal without adding additional network? Should I just invest in a mesh? I have over 50+ devices connected to my router
