TROUBLESHOOTING YOUR INTERNET CONNECTION ON A MAC
By Seth Rosenblum
- FINDING IP ADDRESSES USING ‘SYSTEM REPORT’
Click on the apple in the menu bar, choose ‘about this Mac’ then click on ‘more info’ then ‘system report’ (at the bottom) in the left pane click on ‘Network’ then in middle upper part of the window choose ‘wifi’ or ‘ethernet’ depending how your Mac is connected. Then in the main window you will see all the pertinent IP addresses listed.
2. FINDING IP ADDRESSES USING THE TERMINAL APP
Open the Terminal App (in the Applications/Utilities folder)
To find your IP address type the following command: curl ifconfig.me
To find your default gateway type: netstat -nr | grep '^default'
Ping your own computer: Ping -c3 127.0.0.1
Ping your default gateway: Ping -c3 xxx.xxx.xxx.xxx
Ping Google DNS: Ping -c3 18.104.22.168
Ping Apple: Ping -c3 www.apple.com
If you have a working internet connection you should get response from all the pings. If you don't the first thing to try is 'TOTO' Turn off-Turn on.
- Shut down you computer completely then unplug both your router and modem from the wall (power) wait 30 sections or so
- If you have an ISP supplied combo modem/router then just unplug it, wait 30 and then plug it back in.
- If you have 2 devices then plug in the modem first wait until all the lights come on
- Plug in you router and wait until all the lights come on
- Reboot your computer
