i have got an ultrabook called Lenovo IdeaPad U310 with i7 4GB RAM and 25GB SSD + 500GB HDD. I already installed Mountain Lion. I can boot it up, i have got access to internet, but really slowly :/ My connection lost in frequency of 10-15 seconds.
My Kext is AppleRTL8169Ethernet.kext.
Is there any solutions for good speed & good stability another kext maybe or settings?
