SK Virtual Visit requires an internet connection and a weak connection can result in issues accessing parts of the application or being able to see or hear people. An easy way to test your connection is to navigate to:
This will tell you your speed, which you can compare against the following:
Excellent 1280x720 - 1000kbps (or 1Mbps)
Acceptable 1280x720 - 350kbps
Acceptable 320x240 - 150kbps
If you are not able to match these speeds or are unable to complete a test due to lack of bandwidth, you may need to talk to you Local IT or your internet service provider.
NOTE: it is best to complete this test in the location where you work as bandwidth can change due to the proximity you may have to the router or modem.
