Solved Local Area Connection missing from network adapters, no connection

[Cpwildstar1000]

I have a Windows 7 Home Premium computer that is not connected to the internet. I have checked the drivers and they are all installed correctly and operational. When I go into the adapter settings there is no Local Area Connection adapter. I have included some screen shots of what I am seeing if they help.

Welcome to the Seven Forums.

In that computer management window (while Device Manager is selected in the left pane), select View from the menu bar. Then uncheck View hidden devices. Do you see any Network adapters now?

 

[Cpwildstar1000]

No, the network adapter catagory does not show up

Then it seems that the Operating System does not have the drivers needed to "see" the network adapter(s).

Who made the computer? Acer? Dell? HP?
Model number?

 

[Cpwildstar1000]

It is a custom built computer, the motherboard is a TA870U3+ from biostar

If you have already installed the W7 LAN driver from here...
TA870U3+ :: Motherboard :: BIOSTAR
...and there were no errors during that install
...then I'll have to ask other forum members for help.

I don't see any type of network interface at all showing up under Network Adaptors. Usually you would see the NIC with no drivers installed but I don't even see that.

I would think that installing the chipset drivers for this board first then installing the onboard LAN drivers would allow for an internet connection.

It's always a good idea to obtain the drivers for a particular board before installing the Op system, that way if you can't get online you have the drivers handy without having to search for them using another machine.

Try using this WinAudit - Download to locate the onboard chip. From there you can google to get a driver package for it onto a thumbdrive for install on the failing system.

Usernameissues, I tried to install the windows 7 drivers and it came up with the error in the picture. Chev65, Dont know where i can find the chipset drivers.

 

[Cpwildstar1000]

The only reference that I can find about the network in winaudit shows me what I could see in device manager in the first post. I might not be looking in the right place, never used the program.

.........Chev65, Dont know where i can find the chipset drivers.

Try here:

TA870U3+ :: Motherboard :: BIOSTAR

CP have you tried to update the LAN driver with the Ethernet cable connected? Are you getting lights on the RJ45 jack?
Check the BIOS under Chipset Menu - Onboard Peripherals Configuration and verify that the Realtek PCIE NIC is Enabled.

I would think that updating the drivers for his board would be the first thing I'd try.

I think that it might be a bad card, because I can hook it up with an attachment to usb and it works fine. I also get the icon in the network connections panel.

This is a fairly common problem with the LAN adaptor not showing up, it could be a hardware problem although you can sometimes bring the adaptor back up by shutting down the PC completely, unplug the power cord and then push the power button to bleed all power. Restart and see if the LAN adaptor comes up again. Clearing the cmos is another way to fix this problem.

USB attachment is wireless or Ethernet LAN? Did you go into your BIOS and verify that LAN was enabled? SHould have defaulted to enabled but that would depend on where you got your mainboard. If it is a new card - contact manufacturer because it would be under warranty.

 

[Cpwildstar1000]

It was a ethernet usb. It is enabled, and the card is kinda old. I got a new card and it is working fine.

 

[Cpwildstar1000]

I dont know how to mark it as solved on my phone, so ill have to try to do it later

I'm glad the new adaptor worked. That last one gave up the ghost I guess. I'll mark as solved.

BEWARE - I downloaded that Win Audit from Softonics and the Virus Scanner lit up with "Trojan:Semnager"

Trojan.Semnager | Symantec

VIRUS LADEN SOFTWARE. Apparently my scanner cleaned the files.
