I reinstalled windows 7 from a restart disk for my mom's computer which is a windows 7 home premium 64 bit with a Amd Sempron(tm) 140 processor 2.70 Ghz processor. When I installed everything it failed to connect to the internet and has been telling me that there are no internet connections available. Trouble shoot says that windows did not detect a properly installed network adapter. If you have a network adapter, you will need to reinstall the driver. (<-- I copied it) However I can't find it and I actually have to find it on my computer do to no connection on hers. I have been using my flash drive to transfer drivers but have not succeeded in finding the correct one. Please help I have been trying with no success for the past four hours. It is a dell inspiron 570.
