One time only wired ethernet connection

[newmonster]

Hello,

I am new to Mint. I am using Ming 15. I am coming from ubuntu 10.04. I am having a issue with 'one-time only' wired Ethernet connectivity. Basically, using network-manager, and following boot up, I can plug an ethernet cord in and get connectivity. If I then unplug the cord and plug it back in, the network manager does not recognize the cable and says 'cable unplugged'. This behavior is extremely repeatable.

Some information that might help:

Code: Select all

 inxi -Fxn
Network:   Card-1: Intel Centrino Wireless-N 1000 [Condor Peak] driver: iwlwifi ver: in-tree: bus-ID: 03:00.0
           IF: wlan0 state: up mac: 00:26:c7:60:46:66
           Card-2: Intel 82577LM Gigabit Network Connection driver: e1000e ver: 2.1.4-k port: 1820 bus-ID: 00:19.0

After the first plug in:

Code: Select all

ifconfig eth0
eth0      Link encap:Ethernet  HWaddr f0:de:f1:10:49:68  
          inet addr:143.215.230.216  Bcast:143.215.231.255  Mask:255.255.248.0
          inet6 addr: fe80::f2de:f1ff:fe10:4968/64 Scope:Link

          Interrupt:20 Memory:f2600000-f2620000 

After I have unplugged and then replugged the cable:

Code: Select all

ifconfig eth0
eth0      Link encap:Ethernet  HWaddr f0:de:f1:10:49:68  
          inet6 addr: fe80::f2de:f1ff:fe10:4968/64 Scope:Link

After disconnecting and then reconnecting the cable, does reloading the module help?

Code: Select all

sudo modprobe -r e1000e ; sudo modprobe e1000e

I also appear to have this issue.

I can only get an ethernet connection if the cable is plugged during boot.

If I unplug then plugin again the connection is not ressumed.

Using the suggested command did not help me.

Is there something else I could try ?

I solved this issue on my Lenovo T530/intel e1000e with kernel upgrade to 3.9.

According to arch wiki it's a driver bug solved in upcoming kernels.

It still does not work perfectly, Network Manager stil gets confused and shows ethernet as being off,
but the wired connection/dhcp works every time.

@pomo

Thank you for the info.

I'm on 3.8 something, so will look forward to 3.9 update.

Same problem. Updating the kernel worked for me. Thanks Pomo!
