  "account": "Gigabit broadband and modern 5 GHz routers can fail to meet advertised speeds due to random throughput drops and erratic latency. Default router settings often set them to use a limited range of non-DFS channels in the lower 5GHz band, causing radio frequency saturation in densely populated areas. Users often blame ISP throttling, faulty hardware, or inadequate coverage, leading to unnecessary investments in mesh nodes or hardware upgrades. By manually assessing local RF congestion and shifting 5GHz Wi-Fi transmissions to less congested DFS or higher UNII-band channels, users can alleviate co-channel interference and enhance real-world throughput without purchasing new equipment. The 5GHz spectrum is divided into multiple UNII bands, with channel configurations varying by country. In the US, UNII Band 1 has non-DFS channels 36, 40, 44, and 48, while DFS channels 52 to 64 exist in UNII Band 2A. UNII Band 2B and UNII Band 2C cover channels 72 to 92 and 100 to 144, respectively, while UNII Band 3 contains channels 149, 153, 157, 161, and 165. Co-channel interference, where neighboring access points on the same channel contend for transmission airtime, can result in queue delays and severe latency spikes. Wide 80MHz and 160MHz channel configurations exacerbate this issue, especially in apartment complexes or dense suburbs. DFS channels, standing for Dynamic Frequency Selection, are typically reserved for radar systems and require access points to monitor for radar signals and vacate affected frequencies when detected. These channels can unlock less congested spectrum, but their availability depends on the radar environment and router compatibility. When switching to DFS channels, a mandatory 60-second Channel Availability Check occurs before broadcasting, which can delay router reboots. Legacy client devices may not support UNII-2 DFS channels, causing the 5GHz network to become invisible to them. Before switching, it's advisable to conduct a site survey to identify optimal channels free of co-channel interference and radar interference.",
