Sending large files and opening ‘dodgy’ links when connected to someone else’s network are among the top ‘Wi-Fi-faux pas'

A study of 2,000 adults discovered the ‘rules’ everyone should follow, with not using their phone to go online at a dinner table and not changing someone’s password also featuring.

Others believe you should never use a coffee shop’s connection without buying a drink.

But the average adult admitted to breaking the etiquette rules once a month.

It was also revealed people typically wait less than half an hour to ask for the Wi-Fi password at someone else’s home, and a tenth ask within the first 10 minutes.
