Even some other gadgets and electronics like cordless phones and microwaves can interfere with Wi-Fi as well.
Fortunately, there are possible ways to get the Wi-Fi speed fixed.
It is proven fact that there are some channels which indeed provide more speed than others.
Channels 1, 6, and 11
Most of the modern Wi-Fi home routers broadcast in various frequencies.
The Wi-Fi home networks make use of a narrow radio frequency range between 2.4GHz and 5GHz for signal transmission.
Spacing between the channels is really important as overlapping can result in awful wireless online grid.
Recent observations has highlighted that using the 40MHz channels gets affected due to airwaves being congested.
Similar to television channels, this range has been distributed further into some smaller bands or channels.
Fortunately, channels like 1, 6 and 11 are spaced with enough distance ensuring no overlapping.
802.11 a, b, or g).
Further, stick to channels 1, 6, and 11, if you use 802.11n with 20MHz channels.
What channel should you use in a crowded area?
Channels 1, 6, and 11 are your best choice for minimal interferences and maximum throughput.
For instance, tools like Vistumbler can help you find the best and clearest channel.
Both 802.11n and 802.11ac can offer 23 non-overlapping 20MHz channels.
However, fine tuning the channel on the router might still be required.
