No network after resume from sleep

**Ashimema** · February 11th, 2011

Anyone know if this ever got fixed?

I have a the same problem as originally described. Networking will not connect after a system resume (from hibernate or suspend).

Restarting networking as suggested in a number of posts does not fix the problem?

My NIC is on-board my GA-7VT600-P-L motherboard (So is in fact again part of the Via VT8237 chipset! Gigabyte also claim the actaal chip; VT6103L as the Networking controller.)

More Details:

lshw returns;

Code:

Ubuntu seems to have identified it as VT6102 as opposed to VT6103L? Also, looks to me that there are new drivers (v5.20) on the VIA site.. but their only relevant for kernels upto 2.6.32 and my system appears to be running 2.6.35-25 so i'm a little hesitant at replacing the drivers?

I just hit this as well after my wife borrow my PC and hibernated it (I usually suspend).

My network card is an old Intel Pro 100 82557.

i wanna bump this 'cause i have the same simpthoms eg. no ethernet after suspend to ram (never tried sleep though) moreover the lights on the ethernet socket are both off, when normally at least one is lit even when the cable is unattached.
To restore ethernet functionality i have to reboot my machine.
Wireless is working fine.

i attach my ethtool output for eth0

Code:

@fuzzywolf--

Would you please try this and let us have your report? I am wondering if it makes any difference if it's wired or wireless.
