Ok so i've been having this problem for ages and its time to fix it.
Basically for some odd reason my computer connects to the internet on boot up but then disconnects and i have to manually connect it. If i good to the internet options it says that it will automatically connect to my network when its in range but its always in range and always has the problem that i just stated above.
I run on a home wireless network and i have a TrendNet wireless adapter that plugs into my pci slot in my machine.
i've tried talking to the Trendnet Tech support but they where useless so i've come to you guys.
