Hello, I'm trying to solve what, as far as I can tell, is a relatively rare/unique issue. Been through half a dozen forums with no results. This morning I had a functional 10.8.2 with working internet. I was having some packet loss and intermittent connection drop issues that I isolated to the OSX by testing my connection on my Windows partition and also my Win/Linux laptop. So I figured I might be able to address the issue by trying an alternative kext file for my hardware. I first backed up everything (IONetworkingFamily and my Lnx2max kext). Replaced the necessary file with Slide's new R1000SL release. Repaired permissions, rebuilt cache and rebooted the computer. When I logged back in, I had no internet so I reversed the process back to my original files. When I booted back in, I found out that I still have no internet with the original files that were actually working earlier today. The really weird part is that, under network settings, Ethernet looks "Connected"...
