Things That Can Block Your WiFi
If your WiFi network seems slow, it may be that some other household devices are hampering its performance. A recent study confirmed that consumers lose an average of 30% of the data speed of their broadband connections when they use WiFi at home. Microwave ovens, baby monitors, and cordless phones can all slow down WiFi performance. But your neighbors' WiFi networks are often the biggest source of interference.
The problem is that most existing WiFi equipment operates on the crowded 2.4GHz band, with three non-overlapping channels. For those who live in densely populated areas your neighbors' networks could be interfering with yours and hindering its performance. The solution is to buy a dual-band router that operates simultaneously at 2.4GHz and 5GHz. This will reduce the congestion and speed up performance on newer devices.
