In this case, proxies are not an issue, and are simply a distraction from the real problems.
This will tell you if the Router is reachable, or there are cabling/wirelss signal problems. Mac configuration problems are often solved by using the "Assist Me" button is System Preferences > Network and choosing to set up again.Īnother diagnostic is to try using Network Utility and the Ping function, and Ping-ing the address of your Airport base Station, often 192.168.0.1 or 10.0.0.1 or similar. When you have this IP Address for more than an instant, you should suspect bad cables for Ethernet connections, bad signal strength or interference for wireless, Router configuration problems, or Mac configuration problems. If you do see the 169.254 Address, it can be read as "Nobody will talk to me" or "Nobody will give me an IP Address". In most cases, on most networks, the 169.254 self-assigned IP Address is replaced by a valid Local IP Address such as yyy or 10.0.xxx.yyy so quickly that you never even see the 169.254 Address. This address is only good for talking on a local network segment, for things like asking for a valid IP Address from a DHCP-enabled Router. It is on the same subnet with any low-order 16 bits This is the "self-assigned" range of IP Addresses. There are rules that ensure it is a random address, but they always start with 169.254. But it needs to have an IP address (like a return address) to receive any messages. It wants to send a request to a Router for an apprpriste IP address to use now. When your Mac wakes up, it does not yet have an IP Addresss. Any clues? Somebody must know about this stuff. I posted this issue before but only got one responder and the problem still exists. Installed a fresh copy of OS X 11.5 on a new hard drive. Also, other computer does not have any info in the "Bypass Proxy Settings for These Hosts and Domains" section. Some apps are just not good Mac citizens and use their own network settings, ignoring macOS system network proxy settings. Still, the info (*,local, 169.254/16) continues to appear in the "Bypass Proxy Settings for These Hosts and Domains" section and my IP address is always a 169.254 number.)Ĭomcast cable modem via direct hardwired Ethernet works fine with my other computer, so not the modem. When you’re done, just exit the script with ctrl + c and the network settings will be reverted to their previous configuration. Had to go back and retrash all the plist files to have Proxies go back to "Configure Proxies-Manually". (I tried removing the info and it would cause the "Configure Proxies" selection to default to "Always Use PAC File". No matter what I do, this info (*,local, 169.254/16) appears in my Network Settings in the Proxies section under "Bypass Proxy Settings for These Hosts and Domains". Strangely, this same IP number is similar to info that is in the Proxies section (of Network Settings) under "Bypass Proxy Settings for These Hosts and Domains". For my Mac Mini my Network IP Address always has a self-assigned 169.254 number that I cannot change.
