I have an **Arris** cable modem, and my laptop has a **JMC250 PCI Express Gigabit Ethernet Controller**. I'm unable to connect to its wired network either with NetworkManager, Wicd, or the command-line on Debian Stable. I have tried also running a Porteus (Slackware based) LiveCD, but the result was the same.

I have tried also many times unloading the `jme` module and reloading it, with no options, and also with the options `force_pseudohp=1`, `no_pseudohp=1`, and `no_extplug=1`, but to no avail.

I have also tried turning off the rfkill switch, because I can connect to the Wifi without any problems using NetworkManager.

Here is the log from when trying to connect with the NetworkManager:

```

```

The log from Wicd (which uses standard command-line tools):
