Yesterday I wrote a post on the List of Latest Game Ports, now it is no less important to discuss the list of wifi signal channels. Is it important to control the wifi channel? Isn't there an Auto feature in the settings? Yes, it is important, if you set it to Auto, indeed the router will use a frequency that is not busy. But in reality, it is not so, in fact, interference often occurs, namely frequency collisions with existing wifi signals due to choosing the same channel.
As a result of the signal interference, the bandwidth that comes out of the router/access point (AP) is not optimal. For example, when I first played AP, I set it to Auto. After I checked it turned out that the router was using channel 1. While a lot of wifi was using channel 1 as well. I set the bandwidth setting to 20Mbps (I used Mikrotik, previously also used OpenWrt) apparently after I checked via the AP, it only got around 10 Mbps. I thought, there must be something wrong with the AP or AP that has been damaged.
Because it is not possible (because it is new), there must be something wrong with the settings. After I was browsing and I asked a question in the Facebook group, the experts said there was interference. Must be set manually to a frequency that is still empty or not busy (next time I will discuss this method in a separate article).
How to set the frequency channel? In some APs, they only mention the frequency. There are also APs that personally call channels 1 – 13. Yes, most APs only offer channels up to 11. So we have to know what the frequency of these channels is.
Oh, yes, the channel I discussed above is for the 2.4 GHz frequency. If the frequency is 5 GHz another time. Because most of them are often used in the field, namely the frequency of 2.4 GHz.
WLAN Hotspot Signal frequency list
Channel 1 2,412
Channel 2 2,417
Channel 3 2,422
Channel 4 2,427
Channel 5 2,432
Channel 6 2,437
Channel 7 2,442
Channel 8 2,447
Channel 9 2,452
Channel 10 2,457
Channel 11 2,462
Channel 12 2,467
Channel 13 2,472
Channel 14 2,484
Finally I set it to channel 9 because in my area it is still rare to use channel 9 (each area is different, you must know which channels are empty in your area). After I checked my wifi network, it was able to run normally. I set 20 Mbps yes I get also 20 Mbps.
