DHCP not detected

DisappearingOak · 06-26-2012, 01:45 AM

Hi, I'm using Rosa Marathon 2012 which is similar to mandriva. I have a problem where it doesn't detect my internet connection. I connect via a USB router which uses dhcp. For eth0 it says the device is 'Unmanaged', and further the Cloned MAC address box in it's properties is empty. Most of the distros I've tried set up my connection automatically, like Mint, Ubuntu, Archbang, etc. But I've faced this problem in the kde distros (not sure if that's related to this) like OpenSUSE and ROSA 2012. OpenSUSE had the same problem also. So I want to know how to fix this in ROSA. Please help, thanks.

Not sure there are that many ROSA Marathon 2012 users out there able to help you...

Meanwhile, did you try to get a connection manually using a dhcp client? e.g. I would (as root):
- check that the USB router be recognized and has proper module loaded to talk with it with the 'usb-devices' and 'dmesg|tail' commands issued 30 seconds after plug in;
- check the network interface names with 'ifconfig -a', then if your USB modem's interface shows but not in 'ifconfig' then bring it up with 'ifconfig <iface_name> up'
- get a connection using a dhcp client available on your distribution. I use dhcpcd and simply type 'dhcpcd <iface-name>' but if it not included in ROSA you could use another client like dhclient, dhcp-client, dhcpxd, pump... whatever is available in ROSA, see your documentation
- check the connection with 'route'

Hi,

usb-devices recognized it

ifconfig shows

Code:

          RX bytes:800 (800.0 b)  TX bytes:800 (800.0 b)

the interface is eth1. I did ifconfig eth1 up but no response. Rosa has dhclient but when I do dhclient eth1, I only get a box which says Network is down. Please configure your network. 'route' also has no listing. And the connection 'Network Connection' which is listed as unmanaged says 'No IP address' in one of the sections. I tried setting up a new network connection with IP 192.168.1.3 and gateway 192.168.1.1 (router) on interface eth1, but nothing happens. please help me fix this.

Sorry, no clue.

Out of curiosity, why try so many distributions? Didn't you find one which fits your needs?

I was unsatisfied with the new desktop environments, so I tried a lot of distros to see which I liked the best.

Hope someone is able to help with the connection problem./
