I installed the system on the old computer. I have a problem with access to the Internet. 1) When connected via cable (RJ45) to the Internet OSX sends a ping to google.com and get the answer. I try to go to google.com and safari does not open it. The system can not be upgraded to version 10.4.11, because they do not see the Internet. Why is it not working? 2) WiFi does not see me wpa2 encryption. Only wep. Can I change this?
