The next setting that should be checked it titled Control Channel. Make sure you are on channel 1,6, or 11. To find out why read our WiFi Channels guide.

Now scroll down to the section labeled WiFi Protected Setup (WPS). We highly recommend avoiding WPS if possible. WPS is an easy way in for a network intruder. Learn more in our What is WPS Guide. Make sure to Disable the WPS Config.

That's all there is to it, just click the option of Apply before you exit.
