Yesterday I wrote an article List of the Latest Game Ports, now it is no less important, namely discussing the list of wifi signal channels. Is it important to set the wifi channel?. Isn’t there already an Auto feature in the settings? Yes, it’s important, if you set it to Auto, in terms of features, the router will use a frequency that is not busy. But in reality this is not the case, instead interference often occurs, namely frequency interference with the existing wifi signal due to the selection of the same channel.
As a result of the signal interference, it will result in insufficient bandwidth coming out of the router/access point (AP). For example, when I first played AP, I set it to Auto. After I checked, it turned out that the router uses channel 1. Meanwhile, there are lots of wifi that use channel 1 too. I set the bandwidth setting to 20Mbps (I used Mikrotik, previously also used OpenWrt) and it turned out that after I checked through the AP, only around 10 Mbps could come out. I thought, there must be something wrong with the AP or the AP is damaged.
Because it’s impossible to damage (because it’s new), there must be something wrong with the settings. After I was browsing and I asked on 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 can I set the frequency channel? In some APs it only mentions the frequency. There are also APs that immediately mention channels 1 – 13. Yes, most APs only provide channels up to 11. That’s why we have to know what the frequencies of these channels are.
Oh yeah, the channel that I discussed above is for the 2.4 GHz frequency. If the frequency is 5 GHz, just another time. Because most of what is often used in the field is the 2.4 GHz frequency.
List of WLAN Hotspot Signal frequencies
| CHANNEL | FREKUENSI |
|---|---|
| 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 |
In the end, I set it to channel 9 because in my area it’s rare to use channel 9 (each area is different, right, you have to know which channels are empty in your area). After I checked my wifi network, it turned out to be running normally. I set 20 Mbps yes I received 20 Mbps too.
