Difficulty playing video lessons can be caused by several different problems:
Incorrect software configuration – You can use the latest version of the major browsers for Acellus students, but we recommend that you use the Acellus App. If you are using a browser, check our Technical Specifications page to be sure that your student’s devices are using supported software. In addition, make sure that your students are using the latest version of the Acellus App.
The browser’s cache is too full – Browsers often cache up data in order to minimize loading and buffering times. When students watch multiple videos, their browsers may cache up more data than their computers can hold and still function properly. When this happens, performance suffers, and sometimes Acellus videos will not play. To correct this, clear the browser’s cache.* You can find instructions for how to do this on your browser by doing a quick search on your favorite search engine. If clearing the cache does not work, try having the student use a different browser, reboot the computer, or try a different computer.
*Note: If you are using the Acellus App, clear the cache on Internet Explorer for Windows, on Safari for Mac or iOS, or on the native browser for other devices.
Network/Internet connection problems – If you are using Wi-Fi in your home, we recommend that you optimize your Wi-Fi:
- Use 802.11n wireless for the client computers.
- Use high-quality wireless hardware. Check for interference using the tools provided on your access point.
- Make sure your student’s work area is close to your access point.
- Make sure to avoid mounting the access point close to fluorescent lights, microwaves, other sources of electrical interference.
- Use WPA2 with AES security.
If you’re still having issues after implementing these suggestions, you may be experiencing interference from other access points. Contact your Internet service provider.
Video issues can also be caused by insufficient bandwidth. If possible, be sure that you have sufficient bandwidth to handle the number of students who are using Acellus in your home. (Each video stream is approximately 300 Kbps. Typically, an online user plays video 50% of the time.)
