Does the wireless card always connect to the wireless router? Or does it only do that after rebooting also? You can tell by the "bars" symbol in the system tray in the lower-right corner. If you always connect to the router, but the router only connects to the internet after you reboot it may mean something's wrong with the router.
You've tried "tons of solutions" ... a list of what you've done would be helpful.
Edit: Also, please don't post multiple threads about the same subject. It clutters up our forums. Thank you for your consideration.
