I am running Ubuntu 14.04 with cable internet, and my wireless is detected and connected, but I cannot connect to the internet. I know the problem is with my machine because other machines are connecting to the same router just fine. I can connect via ethernet just fine as well.
Here are some notable tests:
ping 192.168.0.105 works with 0% packet loss, but ping 192.168.0.1 has 100% packet loss.
When I plug in my ethernet, ping 192.168.0.1 works with 0% packet loss.
My wireless name is tg, and the router ip is 192.168.0.1 (where I can enter username and password). I suspect that I need to change my wireless address from 192.168.0.105 to 192.168.0.1. Any suggestions on how to proceed?
