Ethernet Connection problem on Acer Aspire One D255E running Meego 1.2
 

Hi.

I am having this problem with my netbook (Acer Aspire One D255E running Meego 1.2. I removed the original Linpus Lite that came with the device and installed Meego (The original Linupus Lite was a stripped down version of Meego). But after installing the OS, I cannot connect to the internet via the ethernet/LAN port. I typed [ lspci | grep -i net ] and it displayed my ethernet/network controllers:

01:00.0 Ethernet controller: Atheros Communications AR8152 v1.1 Fast Ethernet (rev c1)
02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01).

I also did [ ifconfig ] and it showed all my links: eth0, lo, wlan0. I even pinged my network card:
[ Ping 127.0.0.1 ] and it's responding very well, but when I pinged my router or any web address it returns "...Destination unreachable".

My WiFi works very well, but my wired connection is not working not all!. I've searched the web but no positive result. I am writing from another PC cos I have no wireless router/connection at home to connect the AAO D255E.

Pls any help will be greatly appreciated. I don't know what else to do.

Thank you in advance!

Hello,

could you please post the output of and Markus

Thank you Markus for responding.

Here is the output (I also included the output when I ping my network card):

Well, both Interfaces, wired and wireless seem to be recognized by the system. But non of them is configured, what I mean is that you don't have a valid IP-configuration. Are you using DHCP?

Markus

The output I posted was done using another computer. I ran the 2 commands [ $ lspci -k | grep -iA5 net ] & [$ ifconfig ] on the AAO D255E and copied the output into a USB to another PC and posted it. The netbook was not connected to the internet then bcos I had no wireless internet access to post the result. Here's the output again, with wireless connection (working very well) & LAN cable connection (not working at all) all hooked on; and I'm also using DHCP:

Thanks.

Well, this will never work. Your wired-adapter has an IP-address outside of the network with the wireless adapter.You should check where this address is configured. I assume that both wired and wireless network use the same network. Are you sure that your wired adapter is configured to use DHCP?

Markus

When my ethernet cable is plugged in, it reads "Connected using: DHCP" on the connection panel (I use MeeGo Linux). Then it shows the IP-address and sub-net mask (as shown in the output).

The internet connection on the netbook comes from the same wired+wireless router (I have my LAN cable connected to the same wireless router) and I surf via the wireless connection. I don't know how the wired IP-address is outside the network of the wireless. The wired and wireless use the same network.

Pls how can I reconfigure or correct this?

Thanks for your kind assistance.

Well, your eth0 is configured for the network-address 192.168.0.0/24 and your wlan0 for 192.168.1.0/24. I'd suggest that you change the ipaddress for the wired network to the following settings (static)the subnet-mask remains the same 255.255.255.0
With this settings eth0 is in the same subnet as wlan0 and you can try out if it works.

Markus

I tried it but it didn't work. To configure DHCP I need to create or edit this file "ifcfg-eth0" but I looked under /etc/sysconfig/network-scripts and it was empty. How do I create or edit this file? How do I setup this netbook to use DHCP?

You should read the documentation for your distribution, I don't have any experience with Meego.
Such configuration as a static IP depend on the distribution.

Markus

Meego is very similar to Red Hat/Fedora. I found this sites:
http://www.linuxheadquarters.com/how...rkconfig.shtml
http://www.cyberciti.biz/faq/rhel-ce...configuration/

I says how to create/modify the file ( I need to create it cos it's not in the 'network-scripts' folder) but it does not say how to create and SAVE this file. I got to the editing part but I don't know how to save it from command line. Meego has no info on this.

I'm really stuck here. Thanks for your assistance.

Well, you will have to use an editor and you'll have to do it as root (or with sudo) because you don't have write-permissions in the /etc directory as a normal user.

Markus

The file extension should be " .conf" or " .cfg" or what? Pls I'm not sure what it should be? Thanks.

Well, in the explanation in your first link, here http://www.linuxheadquarters.com/how...rkconfig.shtml you'll have to follow either the steps 2-4 or step 5. That means you can use the /sbin/ifconfig and the /sbin/route command to change the settings or edit the /etc/sysconfig/network-scripts/ifcfg-eth0 file.

Markus

I managed to use the "gedit" command to create the file directly in the "network-scripts" folder, but now a new problem: I initially tried to use STATIC IP to put the wired on the same network as the wireless, now if I try to change it back to DHCP option since I've created the file, it hangs and when I restart the system 'STATIC' connection is already selected and it just can't go back to DHCP option. Is there a way to force the system to use DHCP instead of STATIC IP in the command line? I know this is some thing else but I really appreciate all the help you have given me.
Thanks a lot!

Hi. I just tried Meego live usb on the same netbook but it has the same problem, it cannot connect to the web via wired adapter. The live USB is using DHCP connection but still no connection, it cannot even ping the host/router (192.168.0.). It still displays "Destination/Host unreachable". It's a problem of Meego on Acer Aspire One with Atheros, I think (or maybe it's just D255E models). I wonder why this problem? What do you think?....
But I really cannot thank you enough for your time and assistance.
Thank you! Thank you!! Thank you!!!

Hello,

I don't know much about Meego, it seems not to be a regular distribution, I'd recommend to try another distribution. Ubuntu comes with a "Netbook-Edition", but since I don't know about your experience with Linux (you're no newbie here at LQ) I'd suggest to take a look at Slackware, we have a great community here at LQ, http://www.linuxquestions.org/questions/slackware-14/ where you will find much help if necessary.

Edit: for netbooks (without a CD-drive) Slackware comes with a USB-installer ftp://sunsite.informatik.rwth-aachen...README_USB.TXT
