We recommend conducting a speed test online at Gazelle Speed Test. Results should show
50 Mbps download
2 Mbps upload
Ping below 80ms
Jitter under 30ms.
Note that if there are others in your home/environment that share the internet, your performance will be drastically reduced. The best solution is to plug directly into your modem/router with an ethernet cable to get the most accurate reading from the speed test. If you run the test while connected to wifi and do not pass, you will need to stay plugged into the router in order to ensure the quality of calls.
While it is possible to take calls using WiFi this is not recommended for stable reliable calls. Using WiFi may increase the occurrence of dropped calls and call quality problems. Try different areas of your home and run the speed test and find the optimal space.
