For sure they will not understand what you say. The more different from English, the better. For example, Arabic is a good option.
Oh, wait...
Well, the answers are "maybe (or maybe)", "no" and "I try to, but not too hard"
Although summers are quite hot here (around 32C/89.6F), I live on a hilltop where temperatures are somewhat cooler (26C/78.8F). I take no special measures other than putting it standing verticaly on one of its sides (rather than laying on its bottom side) to increase airflow around it. No air conditioners at home (never felt the need of them).
Just for the curious people out there, it's a Conceptronic.
No desert, no third world country (yet). But only ONE WiFi around: mine.
When I first installed my router, about four years ago, I was able to reach the signal from the garage. Now I'm still able to do it. I didn't measure numerically if the signal degraded along the years or not, but for practical purposes the answer is NO: I'm still able to connect from the garage, with the same two "dots" in the "intensity" display.
So, in my case, the signal did not degrade with time. Therefore, I think the neibourghs deployment theory makes sense: taking me as a "control subject" in the experiment, you can say: "The guy with no neighbours suffers no [significative] degradation in the signal intensity".
Obviously those satellites neglected to fly over my garden. Despite my continuous fight, kudzu, weed (not the smokable one) and other wild plants (and even trees) are invading it more and more.
