Always use a wired connection when possible.  Any glitch in the connection can have consequences for participants.  Participants also may have an improved experience if they use a wired connection.

Always set room bandwidth to DSL over the default LAN

Set video quality to "Low," unless showing actual video.  

When using Screen Sharing, Screen Sharing quality should be set to "Low," unless showing a video from the host computer.

Meeting host should reduce CPU usage as much as possible, quitting background programs that may be running updates or other CPU-intensive processes. Adobe says that if the CPU hits 80% capacity, then it may cause audio/video problems for others.  For older computers, running Adobe Connect alone on the default LAN setting may cause the CPU to hit 80%.

ALL OTHER USERS should be instructed to download and install the Adobe Connect Add-in.  This uses 1/2 the bandwidth of Flash Player running in the browser.  There are also issues with dropping out of meetings and losing video or audio related to cookies in the browser and the cache of Flash Player.  Using the add-in avoids those problems.  Have participants check their own internet speed and whether or not they have the add-in installed with this website: https://greenville.adobeconnect.com/common/help/en/support/meeting_test.htm.

If a participant can't log in, suggest to the student to clear the browser cache and cookies.

Promoting other participants to Presenter increases bandwidth usage, though it is uncertain how much.  Promoting multiple participants to presenter apparently increases bandwidth accordingly.  The same is true of microphone rights.  It uses less bandwidth to give participants control over specific pods (using "Attendee Options" under the Attendee drop-down menu) and to give microphone rights only to those who need it.
