Problems with NetworkManager when using Ndiswrapper

[Nene_mataro]

Hi everyone,

I installed the module ndiswrapper to use my wireless network USB on Linux. After installing the Windows native driver and activating ndiswrapper my internet connection worked properly as well as NetworkManager, in which I was able to select the wired network. However, once I rebooted the system my network manager reports "No network connection", even though the internet still works perfectly. I can't enable the Wired Network option that shows up with the mouse left-button either.
I have another device in my computer, an Ethernet interface. I don't use it, so it is disabled.
I heard about a bug that NetworkManager has, but I don't know how to solve my problem. Any help, please?

Thank you !!!

networkmanager supports only one interface at the time. So when using wireless you cannot use wired network. Which distro are you using?
Post the output of "lsmod" and "iwconfig". Run as root

How can I disable eth0 from the beginning?
Thank you!

[valemon]

To disable eth0 you can try

ifconfig eth0 down

In order to remove interface permanently edit /etc/network/interfaces and remove the entries. You can also disable the in-built ethernet from your bios. I hope i have answered your question. Post back if any problems

[Nene_mataro]

I have disabled the eth0 but networkmanager still doesn't work. It does not see the wlan0. I can navigate, though.

[valemon]

Is wlan0 inserted in your /etc/interfaces? If yes I don't have a clue what would possibly be the problem...

[Nene_mataro]

Yes, it is... I can't figure out what the problem may be... Thank you anyway valemon.

[Nene_mataro]

I solved my problem, network manager requires /etc/interfaces to be empty. Thank you guys!
