Sotirios Papakonstantinou Posted January 23, 2015 Share Posted January 23, 2015 Hello!I have recently downloaded MacOX X 10.10 Yosemite. In my current PC I have a disk with two partitions, and the firstcontains a working Mountain Lion installation. I didn't want to upgrade to Yosemite, in case something goes wrong.So I used Super Duper to clone the Mountain Lion installation to the second partition, then upgraded that toYosemite. So I can know test Yosemite but also keep a working Mountain Lion partition. In Yosemite everything seemsto work OK except network. The card connects to the router (status connected) but I cannot browse pages in Safari,I cannot use Apple Upgrade etc. Changing to manual IP and DNS settings didn't change anything. The troubleshooterrecommends restarting the router, but this didn't help either. The weird thing is that I can ping to the router, the other computers and my ISP DNS servers! So what is going on? Please give full details as I am a novice to MacOS.Thank you in advacePS: My system is an Asus P8H61 m/b, Intel Core-i3, 8GB RAM, nVidia GT 620, Realtek HD Audio + Creative SoundBlasterAudigy, Realtek RTL8111F Gigabit LAN.

alexanderq Posted January 23, 2015 Share Posted January 23, 2015 I had that problem too but with beta versions of Yosemite i suggest to try another kext this for example http://www.insanelymac.com/forum/topic/286937-realtekr1000-v3/ Link to comment https://www.insanelymac.com/forum/topic/304076-cannot-connect-to-internet-i-can-ping/#findComment-2105076 Share on other sites More sharing options...
Sotirios Papakonstantinou Posted January 24, 2015 Author Share Posted January 24, 2015 Hello! After posting the question, I came across this Apple support article: http://support.apple.com/en-us/HT203387 which describes how to fix Safari 5 not connecting to sites by disabling DNS prefetch. I immediately tried the code in Terminal. Of course it didn't work as my problem was driver related, so I found a USB WLAN dongle and plugged it in to use it. MacOS couldn't install a driver automatically, so I used the bundled CD-ROM. However for some reason my Yosemite installation is very sensitive. Any time I change something such as installing or uninstalling a driver, it simply won't boot again and I have to use the installation USB Flash drive to repair it. So I did it once more and after repair it still couldn't see the USB WLAN dongle (driver wasn't installed just the Railink wireless utility), but it could finally connect to the internet using the onboard Reatek RTL8111F Gigabit ethernet card! Of course I don't care what happened and why, I at last can enjoy Yosemite without making a clean installation and having to reinstall tons of programs! Now I have a different problem: I can only boot properly to Yosemite using the installation USB Flash drive! I tried to install latest Clover in the first partition, it boots to Yosemite, but the screen is blank (out of range?) How can I fix that? Please point me to the relevant thread. Should I try Chameleon instead? Thank you!
