Hi @Carolina99,
It is possible this could be caused by a problem with the router, or it could just be Wi-Fi interference, i.e. a neighbours router broadcasting on the same channel as yours, in some circumstances this can cause enough interference for you to lose visibility of your network completely. What model of router do you have ?
In case the router is having problems, it might be worth trying a factory reset by holding in the reset switch on the back for over 10 seconds.
Do you have any devices you can connect 'wired', if so can they access the internet and the router settings ?, if you can get to the router settings using a wired device, can you see if the Wi-Fi is showing as disabled ?
If the Wi-Fi is enabled and the network is sometimes visible and sometimes not, then Wi-Fi interference is the most likely cause. If that is the case you could try changing the channels that your router broadcasts the Wi-Fi signal on, you can use free smartphone Apps like this to see what channels are being used within range of your smartphone, you can then change your router to use channels that are less congested.
