WiFi speed is slow and you're not sure why
WiFi channel width (20MHz vs 40MHz) affects speed. Changing it in router settings can improve performance.
WiFi channels can be 20MHz or 40MHz wide. Wider channels (40MHz) are faster but more prone to interference. Your router can switch between them automatically or you can set it manually.
