This is a brief summary to help you understand how the course information reaches your device, pointing out various causes that may be involved in the malfunctioning of the courses.

The lessons, in the form of video files, are hosted on a server with sufficient bandwidth to serve all students at the same time. These servers are continuously monitored to check that they are working correctly.

These files "travel" from the servers through the internet to your computer, mobile or tablet. They pass through different companies that provide internet service until they reach your home, or wherever you are watching the course from. Our servers are located in a place that is guaranteed to have excellent internet communication. On the other hand, our homes may be located in places where the communication is not very good. This affects our connection quality. We need to be aware of this point when checking if the course is working well.

The connection that reaches us ends in a device (router) that distributes the signal, either by cable or by radio (wifi). If the connection from the computer is by cable directly to the router, we ensure that we have a stable connection, without interference (as stable as our internet provider can guarantee).

 If we connect with a mobile phone, tablet or laptop via radio (wifi), we no longer have a stable connection. As a radio signal, it can be interfered with by other stronger radio signals, by the walls of the house or even by household appliances. This problem occurs on many occasions, so it can be a very likely cause of malfunctions in the course.

When the information arrives at our device it is read by a programme, in this case an internet browser (Google Chrome, Firefox, Opera, Brave...). There are many browsers and it is advisable to try another browser when we see that the operation of the course is not correct.

Browsers (and other programs) have a function called "cache". It is a kind of temporary storage of files. Files are stored in memory, unbeknownst to us, to make everything run faster and smoother. Sometimes, when there is a connection problem, this problem is "recorded", and every time we try to access the course, the same problem appears. To solve this, you can clear the cache of your computer. Or try opening an "incognito" tab in the browser. It is also advisable to exit the browser and re-enter after deleting the cache.

As you can see, there are many variables that intervene in the process of running the courses and our responsibility lies only in the first point, in making sure that the server we have contracted is competent and always works well.

We cannot control the rest of the variables; they are the student's responsibility.

The best thing to do is to check the quality and stability of your connection. Try to access, as far as possible, via a wired connection. To test with other browsers. To clear the cache often, etc...
