RE: wifi connection
If you have the laptop band new, all should be already installed. Your description of problem isnt very good, those 2 wifi/bluetooth are 2 separete technologies.
They might be on same card but work separetely.
The best thing would be to contact phone support and you will resolve it within one call.
Both wifi and bluetooth need driver installed and you should be able to find wifi networks once wifi is turned on and also enabled in BIOS.
Same with bluetooth, you can find devices like phone etc...
Find the number for your country and call them 🙂
If you want to, you can let us know what was it and next time we might help you better 🙂
