Bobster, I got two of
these here monkey bumpers.
One is in the front of the house in the office, takes care of the office, shop, and upstairs.
It's hardwired.
The second is line-of sight, but in the sunroom. That's the extreme back of the house.
It's just set as an extender.
With the two, I have internet goodness aplenty on the entire property.
If I take a minute to explain to my beautiful wife the line-of-sight thing, she'd probably quit moving the extender all the time.
It really does matter with these routers, the speed falls off significantly through two walls or more. Not so much that it interferes with work or browsing, but it'll slow streaming to a point where things may need to buffer.
