2] Open your System Tray and right-click on the Teams icon and select Quit. Now, open the Task Manager and End all the Teams processes.

3] Open File Explorer. Copy the following path and paste it into the File Explorer’s address bar.

This information is available on microsoft.com. If you have selected the wrong plan, you need to upgrade your plan. It will be beneficial for you if you replace your current router with a high bandwidth router.

Wired connections are always more stable than wireless ones. Before replacing your router, you can try one thing, connect your system and the router with an Ethernet cable and see if it helps.

How do you stop students from muting you in Teams?

In Microsoft Teams, only the presenter has the right to mute other participants in a meeting. A presenter simply has to right-click on the other participant’s name in the meeting and select the desired option. If you want to stop students from muting the other participants, you have to make them Attendees. When you make a student an Attendee, he/she will not see any option to mute or remove another participant from the meeting when he/she right-clicks on the participant’s name.

You can do this in the following two ways:

1] During a meeting, select Show participants to view the list of all the participants present in the meeting. Hover over the participant’s name, whose role you want to change, and select More options. After that, select the Make an attendee option. If you want to make him/her the presenter again, follow the same process and select the Make a presenter option.

2] During a meeting, go to the Calendar and double-click the meeting. Select Meeting options. Click on the Who can present drop-down menu. By default, this option is set to Everyone. This means that every person who joins the meeting will get the right to present the meeting automatically.
