Troubleshooting performance issues while connected to the Citrix platform

Using CED virtual labs requires the Citrix plug in and a stable speedy internet connection. If you are experiencing delays, lagging, or connection drops while using Citrix remotely in a CED Lab Computer, there are various potential causes. Such causes can often be related to your WiFi router, ISP, or network. Here are some troubleshooting steps that you can take to help you optimize your connection:



 1) Update the Citrix viewer/workspace application

a.  Click on the citrix app and select update (same for both PC and Mac)


2)  Close and reopen the browser.

a. PC:

     (i.) Firefox – Click on the X in the top right corner; or click on the three bars below it and select exit;

                        or hit alt + F4;



     (ii.) Chrome - Click on the X in the top right corner; click on the three dots below it and select exit;

                          OR hit alt + F4;



b.  Mac:

Mac Users, Please Note

  • If your computer does not have it, please download Adobe's Flash Player (sometimes this can help).
  • When you click on either the CED-Lab214 or CED-Lab479 computers to access it, your computer may "download" a file to access it (no matter if you use Safari, Google Chrome, etc.).  You may need to click on that downloaded file, as opposed to the actual Citrix Workspace app.
