cannot access internet after reinstalling windows 7 on my laptop. after the installation was done, it says something about network adapters and when i go into device manager there are yellow triangles or exclamations next the network controller and ethernet and base system etc. i had this problem before and i remember manually selecting the driver from a list but i do not remember how i did it. also, i do not have a way to download a file to a memory stick or cd and put it on the computer. so please dont tell me to download a driver off another computer and then simply put it on the laptop.
