To reduce the posbility of interference between 2 AP/WiFi Router, Highly recommend that set radio channel manually.
 
Navigate to the '''Network → Wireless → Radio → Edit 2.4GHz'''. Configures as follows:
 
<ol>
 
<li>Select '''Channel''': 11</li>
 
</ol>
 
* '''Note''': For the 2.4 GHz band, the best options are typically channels 1, 6, and 11. These channels are the most widely recommended because they don’t overlap with each other, reducing interference and improving overall performance.;
