Network Adapter  

Alright, I was not on my computer for maybe 2-3 days and my internet was working fine before but now its not connecting at all when i troubleshoot it tells me i need to install a driver for my network adapter. I've tried downloading it from the website Dell and it still dosent work. My internet is up and running on my laptop but i need it on my desktop.

In device manager it does not show a Network Adapter tab so im not sure what im suppose to do.

AMD Athlon II x2 245 Processor 2.90GHz
4.00GB Ram
64 bit
Dell Insiprion 570
ATI Radeon 4200

i've went to the dell website and looked up my computer and downloaded the Network tab and its not working, i go into device manager and its not Network adapters is not showing up in there.

The router is wired and is in the same room as my desktop

I havent removed my network adapter. its still in there , also i reinstall my wndows 7 and im having the same problem. and yes im an admin. I really dont know whats going on , theres no networkadapter in device manager and i think usually it downloads the network adapter manually when u reinstall the computer im not sure whats the problem

I have the same problem as you. I used the cd that came with my MB when I built my PC and the drivers that usually showed up when i ran the cd weren't listed anymore. So I downloaded them from the net and installed them and the damn driver or Network Adapter option in device manager doesn't show up still. I also didn't uninstall anything. I even tried a system recovery without any success.

Looks out like it was defective , I bought a new 1 and it works fine! problem solved

Good to know.

hey. just a heads up, my onboard network adapter was disabled in my bios. I have no clue as to how that happened since i didnt touch it so maybe you should take a look at your bios and see if it's disabled as well. then return the one you bought if at all possible.
