Nework Diagnosis-Script

[fdrake]

This is a script to get a diagnosis of your network to help yourself in case of trubleshoting ( Wi-Fi/Lan). If you are using USB- network adapters is highly suggest that you run a lsusb command next to the scripts. Since i did not include any usb scan for network devices I suggest to use a different script or to change this one to meet your needs.

How-To:

1.download attachment:net.sh

2.sudo chmod +x net.sh

3.sudo ./net.sh

4. After you run the script, a file named ‘results.txt’ will be created.

content of the file

ps. I will be more than glad to edit/add the script under suggestions to make it more useful.
