Use safely: Follow these steps only for a router or network you own or are authorised to manage. Never send Router Portal a router password, Wi-Fi key, MAC address, serial number or private screenshot.

Quick answer: A connection can have adequate headline speed but large queueing delay when uploads or downloads fill the bottleneck.
What this page covers
Compare idle and loaded latency with a controlled, authorised test and a wired baseline where possible.
Step-by-step workflow
- Measure idle gateway and Internet latency.
- Repeat while one controlled upload or download runs.
- Compare wired and Wi-Fi results.
- Test documented QoS/SQM changes one at a time and recheck.
Decision table
| Check | What it tells you | Safe next action |
|---|---|---|
| Idle low, loaded high | Queueing at a bottleneck is plausible | Check upload/download shaping |
| Gateway latency rises | Local Wi-Fi or router queue involved | Test wired and local path |
| Only one device spikes | Client or application load | Check device traffic |
Limits and verification
There is no universal good latency threshold. ICMP replies can be deprioritized, so use multiple observations.
