My internet connection died whilst my router still continued to work (so I could still pick up wifi but had no internet connection). I wanted to tether my laptop to my phone so I could use 4G instead, but my phone was still connected to the shody WIFI.
I couldnt just turn off the WIFI on my phone as then my laptop would not be able to tether. I didnt want to 'forget' my WIFI connection as I do not know the password.
Is there anyway to simply disconnect from a WIFI signal?
