As we travel and work from differing locations connectivity is key.  Almost everywhere we go there will be some kind of Wireless service available, although these may not always be accessible to us.  In the majority of areas, where Wifi access is permitted, we will be able to connect with no problems, however there are a number of occasions where access to Wifi Networks can prove problematic. In some cases, if this is a Wifi network you have used before, simply “forgetting” the saved details you have for the network and then reconnecting will get you back on again – maybe the security settings have changed since you last used it and a refresh is required to get connected again.  Instances where you are required to enter a passcode to connect, check the syntax carefully – a lower case L can look a lot like a number 1, for example – so simple mistakes in translation can prevent access from being permitted.
