Questions on Wifi signals and fluorescence

[Guest guest]

Hi

Nice to find your group. [] Thanks to whoever created it.

A few of questions for the group. Any information is appreciated,

including links to check out.

- We have a lot of neighborhood WiFi signals coming into our house. Is

there a way to block them or reduce their strength?

I've noticed that signal strength can vary even though I've only

traveled a few feet. For instance, there are signals with 2 bars on 1

kitchen chair, and the signals on the chair directly across the table

from it has 3 bars.

Outside the family room glass sliding door are 3 and 4 bars. Inside

near the door is 2 and 3.

- How do the WiFi signals travel? What impedes them?

- Do WiFi signals affect each other when they are in the same location?

- Is there a purchasable meter of any kind that can measure signals from

fluorescent light?
