Screwed something in radio settings

So.. I was in radio settings trying to switch wifi channels because my internet was shakey. I couldn't touch them so I started looking at the other settings, one of which just said 'enable' and I could choose from enable or disable. Standard setting was disabled. I figured what's the worst that could happen, so I enabled it.

My wifi is gone. I can't connect to the internet on any device and I can't get back to those settings because they require internet.

I restarted my router, unfortunately nothing happened. I honestly don't know what I did, and I hope anybody here has a clue.
