3 floor home , each floor approx 900-1000 sq foot. Provider Spectrum (only one I can get) Plan 300 Mbps

Equipment: Nighthawk R7000 (serves as spectrum modem/router) Eero 6 Mesh. Hub connected to R7000 on middle floor. One extender each in basement and 2nd floor.

Speed tests are around 200-250 consistently, sometimes 300-350 on slow hours. Some devices seem a bit slow/laggy at times though, bandwith issue?

Basically I’m wondering if I should be upgrading my nighthawk given the R7000 is like 8-10 years old . And if yes , than to want?

Further question is should I keep the eero 6 mesh network or just replace everything with one beefy modem/router? Or…replace just the nighthawk with a dedicated modem and use my current eero 6 as router/extender?

Purpose is mainly streaming and gaming. Don’t do much work at home. Have about 4 devices on 3rd floor , about 7 on main floor and 5 in basement floor.

Also have a couple outdoor stuff , and doorbell, all Blink set up.

Wondering if I should update my stuff solely based on age, maybe old tech?

Would love and appreciate any advice!! Thanks everyone in advance.
