Asa si la mine mai are momente cand nu gaseste nicio retea laptopul. Incearca sa il conectezi si cu cablu de internet sa vezi ca gaseste reteaua. Incearca sa ii dai un reset la router. Al meu dupa cateva ce il opresc de cateva ori isi revine si gaseste reteaua. Acum depinde de situatie, daca la tine nu il gaseste laptopul in niciun fel poate fi problema si de la laptop.
Intra in setari si deconecteaza-te si apoi reconecteaza-te.
Incearca si asta:

Se pare ca e aceiasi problema ca a ta.
Ai aici un copy paste la instructiuni, poate tie mai usor asa:
1. Go to "Control Panel".
2. Next go to "Network and Internet" and then "Network and Sharing".
3. Now click on "Manage Wireless Networks".
4. On this screen, remove all wireless connections by "right clicking" on it and select "Remove network" from the drop down menu.
5. After doing this, close the oepn windows and reboot the computer.
6. Once the computer is fully reloaded, scan for the "Wi-Fi networks".
7. Click on the available network that you want to access and select "connect".
8. It takes a moment, but then you will be asked to give a password for your Wi-Fi connection. Type in the password and click the "connect" button.
It should now be connected.
NOTE: If this doesn't work, you may want to reset your hotspot, and then once it is fully loaded again, repeat the above steps.
