I've been seeing terms like "tri-band," "4x4 MU-MIMO," and "8 antennas" thrown around a lot in stores lately. So, do we all really need such powerful routers, or will a basic model suffice? Even in a crowded home, how much performance can you really get out of a cheap 2-antenna model? What are your thoughts? What do you focus on to boost wireless network performance?
Is a multi-antenna router necessary or is it overkill?

If your home is on the smaller side and you're not running dozens of devices simultaneously with high bandwidth demands (like multiple 4K streams, massive file transfers, or IoT devices with heavy data usage), a simple router with 2-4 antennas will do just fine. I personally used a budget-friendly 2x2 MU-MIMO router for years in a 4-room apartment with up to 3-4 users without any serious issues—the connection was stable as long as there weren’t other interference sources like microwaves or crowded neighbor Wi-Fi networks hogging the frequencies.
However, I noticed a real difference after upgrading to a **tri-band router with 4x4 MU-MIMO**, especially when handling **multiple simultaneous 4K streams** (e.g., two kids watching YouTube while I download a large file). The extra 5 GHz band and higher throughput really cut down on latency. For everyday use, it’s overkill, but if you’re dealing with **actual network bottlenecks** (constant buffering, sluggish gaming, or a ton of smart home devices), an upgrade is worth it. For me, the **better antenna distribution** (slightly improved range and more stable connections in edge areas) was the deciding factor.
If your home is of normal size (1-2 floors, up to 150m²) and you have heavy Wi-Fi usage (many devices, 4K streaming, teleconferencing), a router with at least 3-4 antennas makes a serious difference. The price is a bit higher, but you might face stability issues with cheap 2-antenna models, especially if your walls are thick. Try to use the 5GHz band more instead of 2.4GHz—it's less crowded.
