Will IOS 8 reset my network?

Yesterday I bought an Iphone 5c and it automatically comes with IOS 7. Which is great. But today IOS 8 installment offer came up and I don't know if to accept it. If I do would I have to reset my network/password etc to get Wi-Fi, because my network is locked at it takes ages to unlock it for the phone to find it? And is IOS 8 good, what does it feature?

I upgraded to iOS 8 and it preserved all my passwords and network settings

  • Wi-Fi on iPhone keeps saying unable to join network (my network name)? How can I fix this! It's been like this for a week but it works on my laptop fine. I tried unplugging it for a few seconds, I tried resetting network settings, I tried turning my phone off then on again, and I know I'm typing it right. I even typed it in upper case AND lower case. Does anyone know how I can fix this?
  • What's the difference between off-network and on-network? I'm try to work out which is best for what I want out of the service. I want protection while on my iPhone 5 (both when connected via Wi-Fi and when roaming on 3/4G). Website with product details: http://www.umbrella.com/products/umbrella-security-features/
  • What happens if I reset network setting on my iPhone? I don't have personal hotspot since I updated to 6.1.3, and someone said if I reset network settings it should come back. Will this affect my Internet or anything
  • Looking for a way to evenly share network speed in a house network? So my problem is that I play games online, that need a good ping. Whenever anyone from any other computer goes to load a video on youtube in a high quality, it takes up all the speed, gives me more than 400 ping and just pretty much cuts everyone else out. Is there a way to share the network evenly between every user? Our download speed is about 6mb/s, so if we have 4 active users, i'd like it to share it like 1.5mb/s each.
