Common symptoms
- The device repeatedly changes between online and offline
- Calls drop while other local functions keep working
- The problem appears only in certain rooms or on one Wi-Fi band
Possible causes
- Weak signal, interference, or aggressive band steering
- Power-saving or network-adapter driver behavior
- Router instability or DHCP conflicts
- An ISP outage that leaves Wi-Fi connected but internet access unavailable
How to diagnose it
- Check whether the Wi-Fi icon disconnects or only internet access stops
- Compare another device in the same place and the same device near the router
- Test Ethernet to separate radio issues from the internet line
- Record the time and frequency instead of repeatedly resetting equipment
Solutions to try
- Move the access point away from obstacles and interference
- Update the router and device network drivers
- Forget and rejoin the network after confirming the password
- Use Ethernet or a better-positioned mesh node for fixed devices
- Contact the ISP only when the wired connection also drops
Frequently asked questions
Can a website diagnose the Wi-Fi radio directly?
No. Browser security prevents direct radio and router inspection. DeviceTriage can observe online state and route behavior, then guide controlled comparisons.
Should I factory-reset the router first?
No. A factory reset removes configuration and often hides the evidence. Start with location, device, Ethernet, and timing comparisons.
