If you’re using 2.4 GHz, the answer is simple. The best bandwidth for 2.4 Ghz is 20 MHz . In the majority of cases, using wide widths on 2.4 GHz isn’t worthwhile. The performance tradeoffs from interference on overlapping channels will likely outweigh the throughput benefits.

The average internet download speed ranges from 12 to 25 Mbps . This is what most people in the US have. But there are other options: “Basic” service will go from 3 to 8 Mbps download speed, while “advanced” service will exceed 25 Mbps (that’s also defined as “fast internet” by the FCC).

In crowded areas with a lot of frequency noise and interference, a single 20MHz channel will be more stable . 40MHz channel width allows for greater speed and faster transfer rates but it doesn’t perform as well in crowded areas. However, noise and interference is not always the issue.
