Nobody wants my info dump. I know way too much about networking and computers. The topics are massively deep, like iceberg levels of deep. One for each topic.

I could lecture for an entire day on the nuance and considerations of picking a Wi-Fi channel, or you can ignore me and just hit "auto" which may or may not take some, or all, of my considerations into account when selecting a channel.

If anyone is keen to hear some generally good advice about home networking, here's my elevator speech:

Wire when you can, wireless when you have to. Wi-Fi is shared and half duplex, every wired connection is exclusive to the device and full duplex. If you can't Ethernet, use MoCA, or powerline (depending on what internal power structures you have, this can be excellent or unusable, keep your receipts). Mesh is best with a dedicated backhaul, better with a wired backhaul. Demand it from any system you consider. The latest and greatest Wi-Fi technology probably won't fix whatever problem you're having, it will only temporarily reduce the symptoms and you won't notice it for a while. Be weary about upgrading and ask yourself why you require the upgrade. Newer wireless won't fix bad signal, or dropouts.

For everything else, Google. That's how I find most of the information I know.

Good luck.

I'll be around in case anyone has questions. No promises on when I'll be able to reply tho.
