Dell Inspiron One 2205 - could not find internet adapter

[bathong188]

I downgraded my from Windows 8 Enterprise to Windows 7 Ultimate, i have a big screen so the max resolution is 1920x1080, but when i downgraded it the max resolution was 1400x1050, and i lost the internet adapter too. I ran the troubleshooter it said "could not find internet adapter" even in Device Manager i couldn't find internet adapter, i might try to install but i think it's not good and i don't know anything about that. btw my warranty has expired.
There are some softwares on the internet that can fix missing files on your PC, but they require internet, if you know how to fix this please don't give me those softwares (but i have a USB 8G)

You need network and video drivers:

Download them wherever you can, and use your USB flash drive to copy them to the Inspiron. Run the installers. I hope that fixes all of your problems.
