We rely so much on the internet that when our connection goes down, or behaves very slowly, it is not only very frustrating but has an impact on our business and personal lives. It's even worse if internet connection problems are intermittent or ongoing!

Getting to the bottom of WHY the problems are happening can be "a needle in a haystack", so this course is intended to provide some basic understanding, along with things to test - in order to identify whether the problem is with something at your premises, the Internet Service Provider or (in the case of Broadband/Fibre) the underlying phone network. This should help to save time (and frustration!) when contacting your Internet Service Provider, as you'll be more informed and can try things ahead of speaking to them.

I produced this course with small business owners and home users in mind - the topic is technical by nature, but I've tried to stick to the fundamentals and break it down into methodical steps. It is focused on Broadband and Fibre (as these are what I had to deal with during my time working in IT infrastructure), but some of the principles could be applied to other forms of internet such as cable.

Later in the course, I touch upon issues relating to Wifi and also the idea of a "Backup" Internet Connection (so you can keep working when you main internet connection goes down). There are also lectures on restarting a router remotely, introduction to IP Addresses (including Fixed IP's) and introduction to firewalls.

Ultimately, no one wants to waste more time and energy than they have to dealing with internet problems, which is why I'm sharing my experience through this course - I hope you find it useful and helpful.

This is best for those who don't know what to do if their internet is not working, but you talk a lot about the dial-up connection which was not commonly used nowadays, otherwise, the course was best.

Clear voice, understandable English and easy to follow presentation. This course can be good for people new to diagnosing internet connection issues, but less helpful if you already have some basic knowledge about networking.
