So I've got my computer hooked up through a D-Link wireless adapter and a D-Link router hooked up to the main computer. For about 5 months I had no problems, but now the Internet will not load. In the taskbar (I have Windows Vista Home Premium) it says I am connected to both local and internet wifi. I can do things in local wifi (ex. get files onto computer from Wifi HD on iPod Touch) but not go online to websites. I know it's a problem with my computer/wireless adapter because the internet works fine on my iPod Touch. I have tried reinstalling the software to no avail. please help?
