This is from dictation.
There are some additional things you might consider. The fact that it works for a while but then stops working is not usually of software related problem unless there is some other task in your system that interferes with your network software settings. If so, it would be some kind of network application that tries to work in the background and wants to take control of the network connection.
You can try booting in safe mode with networking and see if you get a good connection in that configuration. Also, you may wish to create a new user account, login to the new user account and set up your wireless adapter again. Normally each user has to have his own access to a wireless device. So that will give you an opportunity to set up the wireless interface once again.
Another issue is the password security features being used presently. In the past, and even still, the password security features cause me a lot of pain in the lower part of my body. In some cases you may have to relax the wireless security level, perhaps using an older wireless security method. Of course, the danger of that is that somebody could eavesdrop on your conversations and perhaps even getting your computer. So if you do reduce the security level of the wireless, be extremely careful when you do it and don't leave it on in that condition for very long.
If you have another computer or even a tablet at hand, you can check out see how your tablet, smart phone or laptop does with the wireless.
There's a good chance the trouble is with the wireless adapter itself. What I have done is use a cheap wireless adapter I got off of eBay. You can get these things for sometimes less than six dollars and the seem to work as good as the higher-priced ones. In fact, I have a wireless adapter now that actually works better than my Ethernet connection. I believe that adapter is for sale on eBay from overseas and goes for about for five dollars.
Number one thing I am not sure about is the use of 64-bit drivers. For quite a while 64-bit drivers are not available for many of the low cost Wi-Fi interface.
Another thing you can try, only for diagnostic purposes, is to boot up one of the live CDs that are available. These live CDs could be something like Ubuntu Linuxor Mint Linux. You just boot them up in demo mode and they do not require any space on your hard drive. They work in memory alone and even can do Wi-Fi access. So if you can get into your network reliably using a Linux boot disk, that would suggest something is wrong with your Windows Wi-Fi configuration. But if the connection proves to be unreliable even with the Linux demo disc, it would suggest that the trouble really is in the wireless adapter itself.
That is about the best I can do for now.
