Remember the old "box fans",lightninganyplace close (same block) would

Some campers were sleeping beneath a tree when lightning struck that
tree. Those who were sleeping tangent to that tree were unharmed.
Two who were sleeping pointed at that tree required emergency medical
transport being struck directly. Struck directly? Lightnng struck
the tree - not campers?
Lightning that struck a tree only harmed two. Follow the current.
First, the path is from cloud to earthborne charges maybe miles from
those campers. The path was down to tree into earth, up campers head,
down and back to earth via feet, and then on to charges. So yes, only
the two campers who completed the direct electrical circuit suffered a
direct lightning strike.
That is more likely the reason for router failure. EMF from
lightning is so small as to be made irrelevant by protection inside
all electronics.
A direct lightning strike was to the building lightning rod. That
means the entire lightning strike traveled to earth via a wire outside
the wall. On the other side of that wall and only four feet away was
a running computer. Computer did not even crash or reboot.
Destructive EMF fields exist where half facts are posted. Most damage
from nearby lightning is, in reality, a direct strike to appliances.
What was the current path to and through earth? Same question
describes why only two campers suffered from a direct lightning
strike. And suffered massively.
A long wire antenna sees maybe a few thousand volts due to a nearby
strike. Then we reduce that thousands of volts to near zero by
connecting that antenna to earth via an NE-2 neon glow lamp. Notice
how near zero volts is created by conducting only milliamps to earth.
Many will hype the thousands of volts and forget why we make that
induced surge irrelevant with only milliamps through a neon glow
lamp. As noted above, many will preach the dangers of EMF from nearby
lightning by only discussing the voltage; by ignoring current and by
ignoring how little makes the EMF transient irrelevant.
