Missing Ethernet Controller

I have an Acer 603G "upgraded" to Win 7 Pro thanks to this forum.
My current issue involves my ethernet controller. It is missing, when I go to Device Manager (DM) the statement where the ethernet controller once existed now reads "Unknown Device". This started when I unsubscribed from software I discontinued. At first the ethernet controller was disabled, I was able to re-enable it from DM. More recently it disappeared from DM and I was able to re load the BIOS and it would work as of two days ago that doesn't help. The BIOS is P11._B2_A. I have downloaded new BIOS onto a pen drive and this still does not correct bring it back.
Any help will be greatly appreciated.

Thank you. When I did the upgrade someone suggested Driver Easy. I've sent them the information and will let you know the outcome.
BTW, I've contacted the software provider I deleted. I can no longer access their chat room and am relegated to online support. It makes little difference as I'm still trying to get the computer back on line. At that point and depending upon what I discover, I'll get back to them. I had to reinstall their software, but of course could not activate, as I'm not online. So we'll see. I really can't pin it on them, but I don't like coincidences, and I certainly don't like seeing their log in screen as an option to access the internet, especially after I "uninstalled" there software.

If your comp is
Aspire XC-603G

follow the link below

Download to your desktop and point the unknown device to it
IGNORE any comment re unsigned coz it isnt.

Note W7 came driver complete and considering the age of your comp then it will allready be on your system, all you need to know is its description ie realtek xxxxx

I think you misunderstood. I upgraded to 7 Pro from 8.1 about a year ago. It has worked great for almost a yr. 10 days ago I was unable to go online, I discovered the Ethernet controller to be disabled. I turned it on and thought no more about it. On the 4th, it happened again. This time it was not disabled, but no longer listed in DM. I searched this forum, someone else suggested to reload the BIOS, again that worked. At this point I uninstalled the suspect software. Since the 4th I've had to reload the BIOS 2 or 3 times. Until Sunday, NADA. Imagine my surprise when I clicked on the redX in the Internet box and saw the login from the deleted software company. Since then I've trying to find answers in fact even to frame the proper question to get an answer. For what its worth I use Mozilla and Duckduckgo. American Pharoah, bless his little heart seems to have pointed me in the right direction. Even his example was in the same area as my missing controller. Easy driver hasrequested screen shots of the areas in question, im just awaiting a response. Hope this clears it up a bit. Best, Jim W

Easy Driver will post a link somewhat like mine.

The link i posted goes directly to the W7 Ethernet driver for that comp.

IF your old DELETED software still appears then you will also have to REMOVE the Network listing for it as well,
I would also look in Computer >> C >> programes/programs(x86) see if that software is listed, if so DELETE.

to check driver please go DM >> unknown device >> properties >> Details >> Hardware ID's
post the xx&VEN xxxx&DEV detail.

@AmericanPharoah, @Torchwood and the 1423 other viewers. Guess which computer I'm responding on. I was able to download a Realtech driver from the Acer site. D.M. still lists it as an unknown device but at least it is back on line. I'll dig further and get the correct one.
