Netgear troubleshooting
Wi-Fi is slow on only one device
Isolate a single slow client by checking band, signal, driver, background traffic and power saving.
Stop if you notice a swollen battery, burning smell, exposed mains wiring or liquid inside powered electronics. Protect important data before resets, firmware changes or recovery work.
Where this problem appears
One phone or computer on an otherwise fast network.
Symptoms to confirm
- Speed tests are poor on one device while others perform normally nearby.
Likely causes
- The client uses 2.4 GHz, has a weak driver, background sync, VPN or aggressive power saving.
Work in order
Step-by-step fix
- 1
Test beside the router
- 2
Compare the connected band and link rate
- 3
Pause VPN and cloud sync
- 4
Forget and reconnect to Wi-Fi
- 5
Update the device wireless driver
- 6
Disable adapter power saving for a test
- 7
Reset network settings only after simpler checks
If the main path does not work
- Test the same device on another Wi-Fi network.
How to reduce repeat failures
Keep client drivers current and avoid stacking VPN/filtering apps.
Common questions
Is this safe for a beginner?
Some steps require careful technical judgment. Stop before powered disassembly, battery work or wiring changes if you are not experienced.

What should I record before contacting support?
Record the exact device model, software or firmware version, the full message shown, when the problem began and which steps changed the behavior.
