Hey all! I'm new to the whole internet thing and not sure what some stuff means. I have a couple questions, any help would be much much appreciated! Thank you ahead of time and sorry if these questions seem dumb!

What does the Max rate mean? Mine is at 144. Does that fall under the mode for my router channel bc I have it set to 300mbps?

RSSI? My RSSI jumps between -33 to -48

Lastly, I've been told Channel 1,6, and 11 is best used but they all have quite a few people on them. So i went with 10 where no one has it. Is that ok?
