Network keeps failing - heron

[Piddell]

Since my upgrade to heron the network connection keeps failing.
I did a live upgrade but it was so buggy I ended up re-loading from scratch, but this but persists.

I boot up and all looks fine, but I have no access to the network from any application, if I can restore it as follows:

phill@fuzzylogic:~$ sudo dhclient

this is a new feature since my move to heron, all other machines are working ok on the same network

Thoughts?

Happened again this morning, any ideas?

Happened again this morning, any ideas?

That's weird, post these outputs:

lshw -C network

After that, post this one:

iwconfig

[Piddell]

New information!
It failed again this morning, so I thought I would login to the router and see what that thought... but I was not able to access it until after I had done a dhclient. so the problem seems to be that the lan port is disabled.

any way

phill@fuzzylogic:~$ sudo iwconfig

eth0 no wireless extensions.

phill@fuzzylogic:~$

both of these logs were when the thing is running ok

[Piddell]

just looked into admin - network and "roaming" was enabled, so I have removed this and set it to DHCP, will see if that makes a difference

[Piddell]

No change this morning.
I ran system- network tools
When I edit the ethernet interface (eth0) it errors and says no such interface exists. yet it's currently working and the info box below shows all the correct details (ip addresses, data in and out, status: active etc.)

[Piddell]

Same again today - here are the logs before I started it with dhconfig

phill@fuzzylogic:~$ iwconfig

eth0 no wireless extensions.


Which are the same as when it is working ok
