Ever since I updated my iPhone to IOS 8 my Wi-Fi connection has been very slow?

This is really bugging me as I don't know why my Wi-Fi is being slow because I've never had a problem with my Wi-Fi until I updated to iOS 8. Has anybody else had this problem? If so can you please tell me what I have to do to fix it?

Step 1) place iphone into kitchen sink garbage disposal
step 2) buy android or windows phone or literally anything else
