Genesis_ Posted October 17, 2014 Share Posted October 17, 2014 Hello ! I just tried to upgrade from Mavericks to Yosemite like a real Mac without major issues. All went fine, just had to re-apply Toleda's patch for audio, but that's all. However, despite my ethernet is recognized and connected in prefpane, I cannot access the internet. Chrome says I'm not connected, Safari just won't load any page, and so on. I tried to upgrade to Mieze's RTL8111.kext v1.2.3 but still no luck. Does anyone have the same issue ? Thanks in advance. Edit : Tried to install kext to S/L/E, no luck. Link to comment Share on other sites More sharing options...
skyandy Posted October 17, 2014 Share Posted October 17, 2014 Hi, Go to System Preference > Network>Ethernet>Advance. Click Hardware tab. Configure manually, speed 10baseT/UTP, Duplex: full-duplex, MTU: Standard (1500) Hope this will helps you. Link to comment Share on other sites More sharing options...

SwithDrawn Posted October 21, 2014 Share Posted October 21, 2014 Does your adapter connect instantly on boot, or does it take 1-2 minutes to show as connected/get an IP? Can you ping your router? I have a similar issue with a Marvell 88E8053 pcie card after installing Yosemite (a clean install with chameleon). It takes 1-2 minutes for the Ethernet Adapter to connect on startup (in 10.9.2 this is instant). After that, it shows connected, but there's no internet access. I can ping my router but not websites. This card should be natively supported and works fine in 10.9.2. I have EthernetBuiltIn=Yes in my boot.plist and even tried injecting the device properties. I've also tried deleting the connection in the preferences window and deleting the NetworkInterfaces.plist in the /Library/Preferences/SystemConfiguration/ folder. I've also tried copying IONetworkingFamily.kext from 10.9.2 with the same result. I don't know what's changed other than IONetworkingFamily since Mavericks that would be causing this.

Genesis_ Posted October 21, 2014 Author Share Posted October 21, 2014 It's instant . I don't have any router, it's an ethernet outlet directly on the wall. Link to comment Share on other sites More sharing options...
clickmikes Posted October 24, 2014 Share Posted October 24, 2014 I have a similar problem: after upgrade to Yosemite, ethernet works, I can access the internet with Google Chrome, but not with Safari. using the command host google.com gives me their ip address, but ping google.com returns: cannot resolve google.com unknown host ?? any ideas? EDIT: works again. Found this in a forum (insert both commands in a terminal window): sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plistsudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist :-) EDIT2: There is the full information.

Genesis_ Posted October 25, 2014 Author Share Posted October 25, 2014 Still no solution found. I just made a clean install of Yosemite and everything is working fine again. It's coming from the upgrade for sure, but what's messing up ? Link to comment Share on other sites More sharing options...
