Смысл: The main idea is that to maximize Wi-Fi performance in the 2.4 GHz spectrum, one must avoid overlapping channels at all costs, as partial overlap prevents devices from coordinating traffic and causes severe speed degradation. The author advocates for the '1-6-11' rule and explains that sharing a single channel is more efficient than partial interference.
To avoid severe Wi-Fi slowdowns, never use overlapping channels in the 2.4 GHz band; instead, stick to channels 1, 6, or 11, as sharing the same channel is better than partial interference.
Смысл: The main idea is that Bluetooth and WiFi dongles placed in adjacent USB ports can interfere with each other because they share the 2.4 GHz frequency band, and this can be fixed by physically separating the devices.
Placing Bluetooth and WiFi USB dongles in adjacent ports causes signal interference due to shared 2.4 GHz frequencies, which can be fixed by using a USB extension cable.
Смысл: The main idea is that switching from the congested 2.4 GHz band to the 5 GHz band significantly increases Wi-Fi speeds in urban areas, provided that physical obstacles are minimized and high-quality hardware (like router-based clients) is used.
An experiment proves that switching to 5 GHz Wi-Fi and using a router as a client outperforms USB adapters and 2.4 GHz bands in congested residential areas.
