What people actually say.
Karl has been fantastic to work with. He's helped us out twice now on a property I manage, and each time he's been efficient, reliable, and easy to communicate with. I wouldn't hesitate to recommend him and will definitely use his services again.
We reached out to Karl from Why Oh WiFi because we bought a new computer and the internet was terribly slow. Karl worked out the problem and now our internet speed went from 27 Mbps to far higher. I'm also glad we could sort out the printer and find a better deal with our provider.
Karl is absolutely brilliant and great at breaking down and explaining any issues, then rectifying them as well, and installing our boosters. Highly highly recommend.

Now Geelong's WiFi specialist.
I'm Karl. I started Why Oh WiFi because I kept hearing the same story — people had been told to "buy a new router" without anyone actually measuring what was wrong.
So I built a proper diagnostic process: enterprise-grade tools, plain-English reports, honest answers. If you don't need new hardware, I'll tell you. If you do, I'll install it as part of the price.
