Problem
The network connection is active, but data takes longer than expected to travel, causing delays.
Symptoms
Noticeable delay in online gaming or video calls.
High ping times when testing connection speed.
Actions take longer to register in real-time applications.
Latency spikes intermittently rather than staying constant.
Possible Causes
Network congestion from multiple devices or heavy usage.
Distance from the router or weak Wi-Fi signal.
ISP routing issues.
Outdated router firmware.
Background applications consuming bandwidth.
Resolution
Step 1
Run a ping test to measure current latency.
Step 2
Connect via Ethernet instead of Wi-Fi to rule out wireless latency.
Step 3
Close background applications using bandwidth.
Step 4
Restart the router and modem.
Step 5
Update router firmware.
Step 6
Contact the ISP if latency remains high on a wired connection with no other explanation.
Prevention
Use wired connections for latency-sensitive tasks when possible.
Limit simultaneous heavy network usage.
Keep router firmware updated.
