NETWORK NOTES

Wi-Fi or upstream connection?

Wi-Fi is the link to your local router. Internet access also depends on the router and everything beyond it.

Make a fair comparison

1. Move close to the access point and repeat the same task.
2. Compare with an Ethernet connection if available.
3. Check whether another device has the same symptom.
4. Record whether the problem affects local services too.

Change one setting at a time

Switching frequency band, restarting equipment and changing DNS simultaneously makes the result hard to interpret. Keep the original settings so a change can be reversed.

Record the pattern

Note time of day, location, signal conditions and whether the device had just resumed from sleep. Repeated observations are more useful than a single speed test.
