Hi all,
I've been using my desktop(Dell Vostro 460) for 2 years now, It's working fine until recently I am not able to connect to internet. My laptops connects fine with wireless. I tried to replace the internet cables, reset router and modem, none of which work.
I found a solution in this forum-to type "netsh i i r r" in command prompt then restart the computer, it worked for a while, as long as I keep my desktop turned on.
When my desktop were able to connect to internet, a network adapter can be found under Device Manager(Broadcom NetLink(TM) Gigabit Ethernet). I tried to update the drivers, it said "Windows has determined the driver software for your device is up to date".

When I turn off and turn on, my desktop could not find network adaptor again(not in Device Manager anymore), this time even the command prompt reset didn't even work.
Is there something wrong with my NIC card?
I opened the case saw it was like a small silver box on the motherboard. Even I buy a new one, there is no slot in my current motherboard.
Do I really need to change a motherboard and NIC card to solve this problem?
Much thanks!

Yes, it said I need to make sure the cable is connected and stuff, I thought it's useless

I actually used that specific software and found nothing(full-search).
 
you did use that software before (cause it takes time to fully scan your computer.

I did a full-scan using this software when I noticed this problem, like last week
