Hey Guys. I have an early 2011 15" MBP w/ the following specs: Model Name: MacBook Pro Model Identifier: MacBookPro8,2 Processor Name: Intel Core i7 Processor Speed: 2 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 6 MB Memory: 8 GB Boot ROM Version: MBP81.0047.B0E SMC Version (system): 1.69f1 Snow Leopard 10.6.7 (with all updates installed) My internet was working great before I did the firmware update. The update completed normally, and the computer was plugged in while it was updating. Everything works normally since then except the internet. Note that it is every connection, ethernet, airport, mobile broadband, etc that is slow, no matter where I have tried it. In addition to my browsers being slow, (safari, firefox, chrome), skype won't connect and Twitter sometimes works. In order to fix it I have tried: Creating a new location in the network pane of system preferences with updated DNS servers deleted all my plist files related to networking removed and re added network connections rebooted multiple times reinstalled the OS (not a wipe and reinstall, just the standard reinstall of the system files) removed all my internet plugins Nothing has really made much of a difference except reinstalling the OS, but even that was negligible. Any other suggestions on what to try? I am a bit reluctant to do a full reinstall because it is such a pain, but will if I have to. Also, I booted to a known good OS, and it was fine, so it is most definitely a software issue. Any help would be much appreciated! Thanks!!
