Network adapter has to be disabled then enabled after start up

Hi Urban Research,

I think the system model you are referring to is OptiPlex 330, since OptiPlex 3310 is not an available model. Please confirm the system model. Also confirm if you are referring to Wireless Network Adapter or the Ethernet Adapter.

Hi thanks for that,  I checked and this one is an Optiplex 990 and it is the Intel 82579LM network adapter that has to be disabled and enabled on start-up each time which I think is the ethernet adapter.

Any thoughts would be welcomed!

Hi thanks for that, seems to have solved the problem!

Hi, we thought this had fixed the problem, but unfortunately it has come back. I have checked the BIOS and it is A07 dated 9/10/2011, does that mean anything?

Many thanks

Paul

Hi Paul,

Thank you for confirming the BIOS version. Updating the BIOS should help us in further troubleshooting this issue, please follow the below mentioned steps:

Please post with the results.

Hi, thanks for your prompt reply, we tried this and unfortunately it didn't fix the issue. On looking it again I think the issue maybe that on start up the computer is showing 2 networks, one called unknown and the other which is the correct one being called network 2. On start up the user can see the network storage devices etc fine, but just can't access the internet without disabling and enabling the adapter.

I tried to delete the 'unknown network' but had no luck!

Any thoughts you may have would be much appreciated.

Thanks

Paul

Hi Paul,

Please confirm as to where are the 2 networks seen, is it in Network and Sharing Center?

This appears to be due to the Ethernet adapter driver again. Uninstall the Ethernet adapter drivers following the steps in previous post and restart the computer. This time let’s download the drivers from Intel website. Use the link provided below which automatically identifies and finds the Ethernet drivers:

http://www.intel.com/support/network/detect.htm

Follow the on-screen instructions and install the Ethernet adapter drivers.

Do reply with results.

Thanks again for the reply, I tried that, but unfortunately didn't make any difference. The two networks appear in the network and sharing centre. I tried deleting both and re-connecting, the one network appeared and everything was ok. Re-booted the computer and both appeared again!

Thanks

Urban Research,

You're not using any type of network profile when using Intel ProSet wireless or any software associated with your adapter, are you?

Rick

Hi, no network profile or  any associated software as far as I know. Just window 7 64 bit as they arrived from dell

Paul,

Do you have a usb network adapter to try to see if it's findings are the same?

Swap the adapter from another system?

Try a cable that is known to work?
