Hello,
I have an HP Mini 210 running Ubuntu 11.04. About 6 hours ago, I was able to connect to the internet via both wired and wireless. The update manager popped up with some recommended updates, and after restarting my computer, both connections were lost. However, my desktop's internet connection works. I have found a couple posts with the same issue, but both their hardware and terminal outputs were different. I'm not sure what info from my computer you need, but a similar thread posted these four:

it looks as though your ethernet adapter (eth0) has picked up an address: 192.168.1.107. Can you ping anything, even if it is just something else on your LAN and not the internet?

I hope that I'm doing this correctly... Here are the terminal outputs.

When I ping my desktop computer, which is using the same network, with ethernet:
ping 199.111.241.17

PING 199.111.241.17 (199.111.241.17) 56(84) bytes of data.However, the opening line (name@computer:~$) never showed up on the next line.

When I ping my desktop computer with wireless:
ping 199.111.241.17

connect: Network is unreachableAnother thing is that when I click on the network icon, it doesn't give me any option to turn on wireless. Normally "Enable Wireless" would be next to "Enable Networking" and that I would have to check it, and I should be able to view all wireless connections. But neither of these items on the menu are there at all.

Ah it's fixed! I figured that since I updated some stuff, I had to update my driver. So I found this (http://ubuntuforums.org/showthread.php?t=1740963). The only that was different is that the patches that I had to download from post #24 were named differently, so I just patched the files that ended in .patch with the correct names. =D
