First post in the forums. I came across an issue when dual booting my Dell Latitude E6510 with Win7 x64 and BT4. As easy as it turned out to be I saw several other posts with people having similar issues with the same wired NIC, Intel's 82577LM Gigabit Controller.
I had come across several posts suggesting to use the e1000e drivers included in the BT4 native Install, but it appeared I had the same luck as the OPs of those threads; none.
I tried several times searching Intel's site directly for drivers for this particular NIC but didn't have any luck until an obscure google search turned up this link: Intel 82577LM Drivers.
After transferring the tar to an external USB drive and mounting said drive simply following the steps in the README did the trick. Below are the commands I entered after copying the tar to my home directory:
tar -zxvf e1000e-1.2.10.tar.gz
rmmod e1000e; modprobe e1000e
I realize to some of the more experienced linux users this may seem trivial at best. However, I'm coming from a windows background and thought this may help those that are doing the same.
I apologize ahead of time if it's in the wrong section or the topic has already been covered.
