Feel like your “100 Mbps” plan streams more like 10? Before you scream at the ISP, peek at the blinking relic under the TV—odds are it’s the bottleneck. Here’s a cheat-sheet that matches your speed tier, square footage and wallet to the perfect COMFAST router (no jargon, no upsell).

1. 100 Mbps or less | 1-2 people | ≤ 60 m²  

Goal: cheap, cheerful, better than the free box.  

Pick: CF-WR300S (300 Mbps single-band)

Goal: solid 5 GHz for Netflix + TikTok + homework.  

Pick: CF-WR1200AC (AC1200 dual-band)  

Why it wins: 867 Mbps on 5 GHz, 300 Mbps on 2.4 GHz, four-core chip keeps ping steady when the smart-TV, tablet and two phones all scream at once.

3. 100-500 Mbps | 4+ people | 80-150 m² | thick walls  

Goal: one SSID that follows you everywhere.  

Pick: CF-Mesh1200 (AC1200 Mesh 2-pack)  

Why it wins: press one button, nodes wire themselves together; add a third unit if the garden calls. Seamless roaming, no drop when you Facetime from bedroom to kitchen.

Quick reality check  

Don’t pay for AX6000 if your laptop is still 2×2 AC—buy the router you’ll use in three years, not ten.  

Any of the above work straight out of the box; no CD, no command line, no “please hold for support.”  

All support WPA-3 encryption and parental controls—because safety should be default, not DLC.

Match your tier, click “buy,” and let the next movie night be buffer-free.
