View Full Version : [ubuntu] Problems connecting to internet after install

September 5th, 2010, 06:46 AM
Hi, I just installed Ubuntu 10.04 and I am a total newbie.

I am having trouble connecting to the internet - neither the wireless or cable connections work. I have no problems when I boot under windows 7.

When I try going to Hardware Drivers I get the message "Downloading package indexes failed, please check your network status. Most drivers will not be available". I have tried reinstalling Ubuntu to no avail.

Can anyone give me some help?

Thanks a lot!

Welcome to Ubuntu! Hopefully we can get this fixed for you.

First of all, what kind of computer is it? (make and model would be helpful!)

Thanks for your welcome!

My computer is a Acer ASPIRE 5745G laptop.

Also, my ethernet card is Atheros AR8151 PCI-E Gigabit and my wireless card is Broadcom 802.11n

Right-click the Network Manager icon and verify Networking and Wireless are enabled. Otherwise, one of these links might be helpful:

Thanks for your reply.

When I right click the Network Manager icon I see that Networking is already enabled, however I don't see "Enable Wireless"

I went into the first link and then went into Users and Groups > User Previleges > Change User Settings and ticked Connect to wireless and ethernet networks but that didn't seem to solve the problem.

Then I saw this thread http://newyork.ubuntuforums.org/showthread.php?t=1495123 but when I downloaded the AR81Family Linux driver and tried
tar zxvf AR81Family-Linux-v1.0.1.9.tar.gz

I got this


gzip: stdin: decompression OK, trailing garbage ignored
tar: Child returned status 2
tar: Exiting with failure status due to previous errors
Also when I type sudo lshw -C netowrk into the terminal I can see both the ethernet and wireless cards but they are both "Unclaimed"

What should I try now?
