So you're on windows 10
You've turned on your mobile hotspot....
You're wifi is on, and broadcasting
You try to connect to your mobile hotspot wifi from your iPad, Android, etc
Then it says "Incorrect Password" can't join
But you know it's the correct password
After getting absolutely no help from the internet
And confirming that microsoft support is mentally challenged or simply utterly stupid and uselesss
I have found a solution that works for me.....and it might work for you
Go to Wifi, and turn off that Hotspot 2.0 Networks button
and then reconnect to your wifi hotspot.
Voila you're fucking connected!!!!
Sorry for the Vulgar language today, I'm just so pissed at microsoft support for doing absolutely fucking nothing to help.
Bonus for VPN Users:
If you want unlimited speed, and you're using t-mobile or something switch on your VPN (I use express VPN)
Under Network Connections Choose your VPN tap adapter, and under sharing, check "allow other computers to use internet connection", and choose the mobile hotspot you just turned on (it should say, "Local area connection blah, blah).
You should have a faster connection tunneled through your VPN.
