The Italian Red Cross says residents’ home networks can assist with communications during the search for survivors.
On Wednesday a 6.2 magnitude earthquake struck central Italy and killed more than 240 people.
More than 4,300 rescuers are looking for survivors believed to still be trapped in the rubble.
The Italian Red Cross posted a step-by-step guide which explains how local residents can switch off their wi-fi network encryption.

Normally opening a home wi-fi network is risky but added that those concerns are trivial in the context of the rescue operation. The risk is that a hacker might potentially has access to certain devices and files.
However that is nothing compared to the risk of people dying because rescuers can’t get a decent wi-fi signal. Besides what sort of psycho goes to a town like Amatrice so they can launch a cyber-attack on someone else.
