I visited a customer today who had a problem connecting to her Wi-Fi with a number of her devices. In the list of Wi-Fi networks that were showing, either the identity of her router did not show up, or the device was connected, but with a weak signal.
This is a common occurrence, and the reason why this happens is because the security of the Wi-Fi signal is very high risk. The router that she currently used is at least 8 years old and the software had not been updated. Usually, broadband providers send to their customers new routers every 3 or 4 years, and so these routers have the new software installed. I found out that day, the customer’s broadband provider had completely stopped delivering the replacements. The result being that the older routers contained archaic software that affected the security of her Wi-Fi.
From a technical point of view, the name of the protocol for the updated software is WAP (Wireless Application Protocol), the versions that is at risk are WEP, WPA and WPA2 (Wi-Fi Protected Access).
The way round this problem is to connect a device via ethernet cable to the router and reconfigure the router to the WAP version. Job Done!
