@Genetic assuming you have not got a Sky router not more than 10 years old you should not be using WEP wifi security as all Sky hubs offer WPA2-PSK as the default wifi security. The latest white Sky Wifi Max hub default to WPA3-T a even more secure standard.
If worried that the setting has changes you can reset your Sky hub by pressing and holding in the reset pin until the power light flashes which will return all settings to the defaults. If your router is really old call Sky to get it changed.
