Hi all, ever since I got the MBPr for work several months ago, I've been having intermittent problems with my internet. Sometimes when I start up my computer, it would show I'm connected to wifi but I cannot access the internet. I have also connected the Ethernet to Thunderbolt adapter. When this problem occurs, the ethernet adapter and wifi are both shown as connected in Network settings. If I turn wifi off and back on, the icon would no longer show as connected and has a ! symbol on it and it would show disconnected in Network settings. Usually, a restart fixes this but sometimes takes several tries.
This problem occurs whether on my work network or home network. My coworkers with MBPr and connecting to the same network have no problems.
I've been to Apple Store 5 times already and they have NOT fixed it nor do they know what's going on. They've ran their Genius Bar hardware test every single time with no problems and it connects to their store wifi too. Here is what I've tried.
NOTE: When I first installed MBPr, I did a restore from Time Machine. I thought this was the problem but I did a clean reinstall of Lion OS without any Time Machine recovery and still same problem...
1. All system updates available installed.
2. Disabled Bluetooth when problem occurs, no difference.
3. Factory reset network settings.
4. Wiped everything and reinstalled Lion 10.7.5, no recovery/migrate from Time Machine except for applications.
5. Apple replaced logic board.
6. Factory reset network settings again.
I'm still getting the problem occasionally. But now, it's starting to kick me off while I'm on the network. Before, it would only occur when I start up the computer (I don't put my computer to sleep). I've grown so tired of going to Apple Store back and forth. Has anyone else experienced this problem?
Any help or tip is GREATLY appreciated!
