Connection problems need to ipconfig /release allot ( windows only)

as of the past few months I have had Connection problems need to ipconfig /release then ipconfig /renew in order to connect it don't matter which PC LAN or either of my Laptops wifi I am on as of lately it seemed to be getting worse . After unplugging my shaw router over night ( thinking something funny with it) also reset it more then once the problem seemed to persist. So I did some testing, I installed Linux ( on one of my PC's) and tried that over a period of time and left my other PC's and Laptops using windows and discovered that this seems to only happen with windows . To make sure, over a period of a week I then installed linux ( dual boot ) on all of my systems and the problem went away Obviously it is a windows issue but I am just wondering if any one know of a fix for this problem
