Troubleshooting
Laptop Wi-Fi Drops After Sleep: What to Check, in Order
A laptop that's opened again should simply reconnect. If you have to switch Wi-Fi off and on every time, one setting is almost always involved.
Troubleshooting
Wi-Fi Printer Keeps Going Offline: Causes and the Order to Fix It
A printer rarely truly drops off Wi-Fi. More often, the computer is looking for it at an address it no longer uses.
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.
Troubleshooting
Network Problems After a Power Outage

Troubleshooting

Troubleshooting
Phone Won't Connect to Wi-Fi After a System Update
The router hasn't changed, the password hasn't changed, other devices work, only the freshly updated phone refuses. It's almost always the phone introducing itself to an old router in a new way.
Troubleshooting

The Rp300k provider router is replaced by a Rp1.5m Wi-Fi 6 router, and the speed test goes down. The router isn't at fault, a new router ships with defaults that may not suit your home.
Troubleshooting
Smart TV Slow on Wi-Fi While the Phone Next to It Is Fine
The TV is in the same room as your phone, on the same Wi-Fi, but Netflix on the TV buffers while on the phone it doesn't. That's no coincidence, TVs really are different.
Troubleshooting
Router Keeps Restarting by Itself
All the router lights go off then come back on, the Wi-Fi vanishes for a minute, then returns as if nothing happened. If this happens more than once a day, something needs checking.
Troubleshooting
Streaming Buffers Despite a Fast Speed Test: Here Is Why
