Portal Tech publishes practical, carefully sourced guides for people who want to understand and maintain the technology they use at home.
Our focus
We concentrate on home networking, Wi-Fi, internet troubleshooting, device maintenance, backups, privacy, and digital safety. This focus reflects the author’s training in Computer Networks and keeps the site accountable to a defined area of expertise.
Who writes the guides
Luan Wagner dos Santos holds a degree in Computer Networks from Cruzeiro do Sul University. He writes and reviews the site’s procedures, explains the limits of each test, and links to the documentation used.
How to use this site
Start with the symptom, record a baseline, change one variable at a time, and keep a rollback path. A guide cannot see your equipment or replace a qualified technician, but it can help you collect better evidence and avoid unnecessary purchases.
