Hi Mike Kalinski,
I’d suggest that you try flashing the A13 BIOS version again to check for issue resolution.
Also, I’d suggest that you run the diagnostics on the computer by following the steps mentioned below and check if there is any issue with the network card on your system.
- Turn on or restart the computer.
- Immediately at the Dell logo screen, starting tapping the <F12> key once a second until the One Time Boot menu appears (if the computer boots to Windows turn the computer off and try again).
- At the One Time Boot menu, press the <Down> arrow key to highlight Diagnostics, PSA+ or Enter ePSA, then press <Enter> to begin the hardware Diagnostics.
- Write down any error codes listed. Reply to us with the error codes.
