|From your statement :|
"I have to Open network connections select properties then wireless settings and tick the box "Let windows configure my wireless network settings" "
It sounds like you have a 3rd party or native client that is associated with your wireless adapter. This wireless client is occasionally setting itself as your default client for managing your wireless network adapter and connections but the problem is that you probably haven't set up the client to work with your router/access point. So when the client sets itself as default and loads up, it doesn't connect to any wireless access points thus you have no connection. What you must do to fix this is either entirely disable the other wireless client, uninstall this client, or setup the client to connect to your router/access point properly and use it as your default wireless monitoring utility. There is no point in just switching to the windows configuration to manage your wireless connections while leaving the other wireless client on. This wastes computer resources because this piece of software is running in the background doing nothing.
I hope this is the case and you will have this resolved your problem with this solution.
