I have a Dell Inspiron 560 series desktop running Win7 Home Premium. I upgraded to Win 10 several months ago and all was well til October when the internet stopped working. I then reinstalled afresh Win 7 via a purchased BUSB from Dell including basic drivers but this did not resolve the internet issue. I tried to obtain the system info you require but recd message" No .NET Frameworkv4.030319" so I can only provide you the following at this time:
BIOS A05 11/10/10
Pentium Dual Core E email@example.comGHz
Service tag 5VJ7CP1
Computer says I am not connected to a network. The Realtek PCle GBE Family Controller network adapter from the original Win 7 installation is absent. TheWAN miniport adapters are listed only. I downloaded the Dell drivers available from a laptop and transferred them via USB drive but when I tried to install them an error message indicated deep sleep mode was on. I changed the sleep power option to never but still no internet. I did reinstall Win 7 again but this did nothing.
I would appreciate any help or advice this great community can provide. Annie
