Dell Inspiron laptop n4110-6 gb RAM- 575 gb HD- intel i-5 processor 1333mhz. Win 7 -64 bit

everything was fine until yesterday...started up laptop and noticed the network connection icon in my task bar hd the "red-x" through it...i knew something was up cuz i had ethernet hardline in to my machine. after I had inspected every possible home netwrok issue...i noticed it was more pc related.

now i go to my device manager to check my network adapters..... there are NONE listed...i go to "View" to find that unhide all devices and note there are only wireless drivers in this device and NOT the typical "realtek-8111E" controller that SHOULD be listed.

So far...i have done these steps

1) ensured BIOS (my cmos is phoenix tianos build) lan settings are correct- done

2) Removed RAM from slots

3) Removed Cmos Battery

4) waited for 15 minutes.

it is still not working ....anyone know about this issue? i even tried a clean install of win 7 and that doesnt work

bad MB? bad network controller? this is terrible....happened out of nowhere.

anyone that can help ...please!!!

best
