I'm I able to Band Lock? If so how do I?

[TerriVegan]

i have the same setup. I have the router and everything all in the same place. I was getting about 20Mbps-30Mbps and all of a sudden 3 weeks ago the signal changed and got weaker.

I've unplugged and moved my router to various parts of the house and the number are just about the same.
