Wi-Fi, internet security, connection troubleshooting, and networking for small businesses. All written in-house.
Security
The Dangers of Free VPN Apps and How to Judge One
Running VPN servers is expensive. If you aren't paying with money, something else is paying.
For Business
Wi-Fi for Libraries and Community Reading Spaces
Library visitors come to sit for a long time. The network has to hold up for hours across many people, without one user taking all of it.
Regulation
Permits and Obligations for Paid Wi-Fi Businesses
The line isn't drawn by the size of the business. It's drawn by whether people pay for the access itself.
Hardware
Planning Your Network When Building a House
The most expensive networking decision in a house is made before the house exists, usually by someone not thinking about networking at all.
Security
Two-Factor Authentication and Account Security
Most accounts that get taken over weren't guessed. The password was already known, leaked from somewhere else and reused here.
Security
File Sharing Security on a Local Network
Sharing a folder locally feels safe because only people in the house can see it. The problem is that a local network is rarely as small as imagined.
Networking
Network Requirements for Live Streaming
A stream that fails mid-event is almost never about download speed. Upload decides it, and upload is often a tenth of the number printed on the plan.
For Business
Networking for Catering and Cloud Kitchens
In a kitchen with no dining room, internet isn't an amenity. It's the only door orders come through, and a kitchen is the worst place to put a router.
Regulation
Moving Your Internet Subscription
The costliest mistake when moving house is cancelling first, then discovering the new address is outside the service area.
Hardware
Documenting Your Own Network
The expensive part of an outage isn't the repair. It's the time spent remembering how the network was set up in the first place.
Troubleshooting
Testing Your Network After a New Installation
Installation defects almost always surface days later, once the technician has gone and the evidence has disappeared.
