Unable to create shared Internet WiFi connection

Hi,

I would like to share the Internet connection I have via Ethernet with other devices using my laptop's WiFi antenna. I have tried to create a WiFi network using NetworkManager but I'm unable: it starts doing it, but when the two dots of the icon are green it restarts again a again, and the network is never created.

I have tried to do the same using a live cd from another distro and I could do it in the first try, so I think there should be a problem with my installation. I'm using Arch Linux for 64 bits processors, with the latest version of NetworkManager (0.8.1-1), and lspci gives me the following:

>  lspci | grep Net
00:19.0 Ethernet controller: Intel Corporation 82562GT 10/100 Network Connection (rev 03)
10:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

So my wireless antenna has the BCM4312 chip. Currently I'm using the driver that can be installed from the AUR (broadcom-wl -> http://aur.archlinux.org/packages.php?ID=19514).

I could post some files if needed. Thank you!

Re: Unable to create shared Internet WiFi connection

if u want to share the connection with wifi, you need to turn your wireless card into master mode using iwconfig, and then bridge it with the ethernet device.

this can only work if your card supports master mode, otherwise you will have to configure it with ad-hoc mode (only one device can connect if it support ad-hoc mode, and difficult to set up)

You could use ip masquerading: https://wiki.archlinux.org/index.php/Internet_Share

Re: Unable to create shared Internet WiFi connection

Nice! It does work nicely, but I'm looking for a method to protect the network with a WPA/WPA2 passphrase, I'll post it if I find something.

Thank you!
