Hi. In the UK, on O2 network.
Trying to use my phone (S21) as a hotspot for my laptop. Connected via USB cable. In connection settings I go to 'Mobile Hotspot and Tethering' > turn ON 'Mobile Hotspot' > turn on 'USB Tethering'. On my laptop, under Wi-Fi, I can then see my phone. When I select 'Connect', it asks me for a 'Network Security Key (NSK)'.
I have no idea what that is, it isn't anything I can find on my phone, it isn't my home Wi-Fi password. EVERY post I've read about it is incorrect. Does anyone actually know what the NSK is, and why I'm being asked to enter one?
OK, update.
I've just found out when you turn on 'Mobile Hotspot' you can can tap it again to open some additional options. In there is a PASSWORD (not a NSK). I tried that and it also didn't work. So, the issues persists.
Hi @Members_3eq0dtK ,
this look like the password set on your device to access the network. You can find this from the phone Settings> Connections> Mobile Hotspot and Tethering> Mobile Hotspot> Search for Set up Wi-Fi hotspot or similar. On that screen you will see an option to set the network name, security, password and network band. You can change them or keep them as they are.
I'm sorry to hear that you feel that this doesn't help. I was trying to guide you to get this sorted following the advise given by other users in post like this: Solved: Tethering hostpot network security key prompt? - Samsung Community - 2481488
I can also see that this is not available for some providers, have you checked with your network provider if they do offer this? More troubleshooting steps to make this work can be found here: Unable to tether a Galaxy phone to a computer using USB cable (samsung.com)
That means you trying to connect with mobile hotspot and the Network security key is nothing but the password that you have set up for this hotspot.
For usb tethering, turn off Wi-Fi on your laptop. You should see the following symbol -
