You’re at your neighbour’s house, and their Wi-Fi is blazing fast. You sneak in for a quick Netflix binge. Harmless, right? Not quite. According to lawyers, even briefly using someone else’s Wi-Fi without permission can land you in legal trouble.
"Under Kenyan law, using someone’s Wi-Fi or hotspot without permission may amount to unauthorised access of a computer system, especially if the network is password-protected," explains Mary Audi, senior associate at Muri Mwaniki Thige & Kageni Advocates.
"Even if the Wi-Fi is open, intentional access without authorisation can still be interpreted as a violation of the law."
The main law covering unauthorised Wi-Fi access is the Computer Misuse and Cybercrimes Act (CMCA), specifically Sections 14 and 15. Section 15 also covers cases where someone accesses a network with the intent of committing another crime, such as fraud or identity theft.
"The Data Protection Act may also apply, but only if the access leads to viewing or processing personal data," adds Fridah Muriithi, associate advocate.
"For instance, accessing emails or browsing histories without permission could result in liability under both the CMCA and the Data Protection Act."
Even the Penal Code could apply in certain cases, considering unauthorised Wi-Fi use as dishonestly obtaining services, similar to electricity theft, if tied to fraudulent activity.
Most cases are treated as criminal matters, but a Wi-Fi owner could pursue civil action if they can demonstrate actual loss or misuse of data.
According to Audi, "A civil suit is possible if the owner proves quantifiable loss, such as bandwidth theft leading to financial harm or misuse of personal data."
Penalties under Section 14 of the CMCA can include a fine of up to Sh5 million, imprisonment for up to three years, or both. If access is obtained with the intent to commit another offense, penalties can increase to Sh10 million, 10 years' imprisonment, or both, even if no actual harm occurs.
Although the law is clear, prosecutions for "simple piggybacking" are rare. "Law enforcement typically prioritises cases involving fraud, hacking, or cyber harassment. Most neighbour disputes are settled informally."
There are situations in which using Wi-Fi is acceptable, such as public networks in cafés, hotels, or on public transportation, or when the owner gives consent, either explicitly or implicitly.
To protect themselves, Wi-Fi owners should use strong encryption, change the default router credentials, create guest networks, and monitor access logs. Users should always ask permission before connecting; even brief use could technically trigger liability.
"Many Kenyans think using a neighbour's or unsecured Wi-Fi is harmless borrowing," says Audi. "People assume that open networks or brief access carry no consequences when, in fact, unauthorised use can lead to criminal liability or civil claims."
While you’re unlikely to be hauled to court for a one-time Netflix binge on your neighbour’s Wi-Fi, Kenyan law is clear: unauthorised access is illegal.
The safest approach is to ask first, stay cautious, and enjoy public Wi-Fi responsibly.
