Start with measurable causes
Do not infer the source from one speed number. Compare the same device, destination and time under controlled conditions.
CONNECTION DIAGNOSIS
Why Does My Internet Keep Dropping?
Repeated connection drops can come from unstable Wi-Fi, overloaded equipment, signal problems, congestion or competing traffic. Look for a pattern across time, devices and wired versus wireless tests.
Compare, don’t guess
Monitor several tests over time. Keep other variables stable, then change one condition at a time.
What can create this pattern
Wi-Fi signal or interference changes
Confirm this possibility with a repeatable comparison before changing equipment or service.
The router or modem becomes overloaded
Confirm this possibility with a repeatable comparison before changing equipment or service.
Background traffic starts and stops
Confirm this possibility with a repeatable comparison before changing equipment or service.
The access line or upstream route is unstable
Confirm this possibility with a repeatable comparison before changing equipment or service.
Test it in this order
Monitor several tests over time
Record the result, keep the test comparable and continue only after this step.
Compare two devices
Record the result, keep the test comparable and continue only after this step.
Test over Ethernet
Record the result, keep the test comparable and continue only after this step.
Record modem warnings or outage times
Record the result, keep the test comparable and continue only after this step.
Use more than download speed
Read throughput together with ping, jitter and packet loss. A browser result describes this device, route and moment; it does not by itself prove an ISP fault.

Why Does My Internet Keep Dropping?
Repeated connection drops can come from unstable Wi-Fi, overloaded equipment, signal problems, congestion or competing traffic. Look for a pattern across time, devices and wired versus wireless tests.
What should I test first?
Monitor several tests over time. Jitter, loss and minimum speed reveal instability that an average can hide.
Does one test prove the cause?
No. Repeat comparable tests over Ethernet and Wi-Fi, on more than one device and at different times.
MEASURE BEFORE YOU CHANGE

Save the result, repeat under comparable conditions and use the difference as evidence.
