Does your Wi-Fi feels much slower than you expect it to be? Is it typically slow at the times when your neighbours are also at home, just after work for example, on weekends? Does it perform better when most of your housemates or neighbours are asleep? In the affirmative in some of these questions, you may be experiencing Wi-Fi channel overcrowding. If channel overcrowding is the issue, you can solve it easily by moving your wi-fi router to a quieter channel.
