Wireless connected but no internet access
15
I'm using ubuntu 15.04 vivid, I'm connected to the wifi but when I open Firefox, it said "Server not found", I open Software Updater it said Failed to download, basically no internet access.
But I've used ubuntu 14 before and I could use the wifi normally without any error.
Also my Windows and my phones work without any error too.
I've clean reinstall several time and I have the same problem.
Here is some information about my situation:
My wifi device is: Huawei HG8045A

I'm using ubuntu 15.04 vivid, I'm connected to the wifi but when I open Firefox, it said "Server not found", I open Software Updater it said Failed to download, basically no internet access.
But I've used ubuntu 14 before and I could use the wifi normally without any error.
Also my Windows and my phones work without any error too.
I've clean reinstall several time and I have the same problem.
Here is some information about my situation:
My wifi device is: Huawei HG8045A

Could you add ping result for the three DNS servers you have specified in /etc/resolve.conf?

I'm using ubuntu 15.04 vivid, I'm connected to the wifi but when I open Firefox, it said "Server not found", I open Software Updater it said Failed to download, basically no internet access.
But I've used ubuntu 14 before and I could use the wifi normally without any error.
Also my Windows and my phones work without any error too.
I've clean reinstall several time and I have the same problem.
Here is some information about my situation:
My wifi device is: Huawei HG8045A

I'm using ubuntu 15.04 vivid, I'm connected to the wifi but when I open Firefox, it said "Server not found", I open Software Updater it said Failed to download, basically no internet access.
But I've used ubuntu 14 before and I could use the wifi normally without any error.
Also my Windows and my phones work without any error too.
I've clean reinstall several time and I have the same problem.
Here is some information about my situation:
My wifi device is: Huawei HG8045A
