network manager problems

**mo.reina** · November 6th, 2009

ok let's do a step by step process to make sure that network manager isn't interfering:
right click on the network manager icon and unclick "enable networking"
now go to the terminal and enter this command

Code:

ifconfig

post the output of the command, but the only thing that should come out should look something like this:

Code:

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:288 errors:0 dropped:0 overruns:0 frame:0
          TX packets:288 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:24688 (24.6 KB)  TX bytes:24688 (24.6 KB)

now enter this command:

Code:

ifconfig eth0 up

that will tell your computer to activate your ethernet interface
hit ifconfig again, something like this should come out:

Code:

eth0      Link encap:Ethernet  HWaddr 00:1f:c6:2f:85:9d  
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
          Interrupt:248 Base address:0xe000 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:341 errors:0 dropped:0 overruns:0 frame:0
          TX packets:341 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:28849 (28.8 KB)  TX bytes:28849 (28.8 KB)

you'll notice that eth0 is now included in the output
now hit the dhclient command again

Code:

dhclient

now try to surf. make sure that your browser isn't in offline mode.

ifconfig

Code:

 jay@ubuntu:~$ ifconfig
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:283532 errors:0 dropped:0 overruns:0 frame:0
          TX packets:283532 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:52497849 (52.4 MB)  TX bytes:52497849 (52.4 MB)

jay@ubuntu:~$

ok im able to surf with it disabled so anyway to keep it enabled & not have it pop up every few minutes?

**-jay-** · November 6th, 2009

so do i have keep it disabled always???

**mo.reina** · November 6th, 2009

well if you can surf by connecting through the terminal it means that the problem is network-manager, not your connection or your hardware.

i'd suggest removing then re-installing network-manager. if the problem re-appears you can try using wicd instead, just do
apt-get install wicd

oh and please have the thread marked solved, it saves time for other searchers with the same problem

I would try disabling ipv6. your 'stable connection' is only lacking an ipv6 address and your log showed no ipv6

try that and see if it works
