expand from ethernet to wireless

**bobescalin2005** · 03-25-2009

I have a question. It is possible to take the internet from Ethernet card and expand it by the wireless card?

I have 3 network card on my desktop PC, 2 ethernet and 1 wireless. The internet came in my from one of the ethernet card, and i was wondering if it is possible to give the internet from my desktop to my laptop from wireless card. I hope you understand what i am saying!

Cheers!

If I understand correctly, you want your desktop PC to act as a wireless access point? This is definitely possible. If you google there are many guides, or someone here might be able to help. It would help to know which distro you're running. Build A Linux-Based Wireless Access Point

**bobescalin2005** · 03-25-2009

Yes, I guess Acces Point it`s called

I did on windows XP and worked fine! I didn`t know that this is possible

I create a ad-hoc connection wich i connect to the laptop and then i made a bridge connection with ethernet. I don`t know how to do it on linux (opensuse 11.1).

Not all wireless cards can be used as an access point. Take a look at this this list, is shows which work as an access point (AP).

Drivers - Linux Wireless

You will need to know more about your wireless device, especially the driver module. You can use this How-To as a guide to find that information.

Wireless Setup - Srart Here

The wireless would be set as an AP using the iwconfig command. It is referred to as master. For more info, read the iwconfig man pages.

Code:

man iwconfig

Ok Paul, i have looked at the

Drivers - Linux Wireless

but i didn`t see my model there. But i`m sure it support AP too.

I read you guide too "Wireless Setup" and my wireless card is on usb. The output from the lsusb:

Code:

Bus 004 Device 002: ID 0b05:1742 ASUSTek Computer, Inc. 802.11n Network Adapter

The result of the command

Code:

$ dmesg | grep firmware

doesn`t return anything so i guess i don`t have any firmware errors.

What i am sure it use it the "rt2870sta" kernel module. It is a ralink one.

What i have found in dmesg:

Code:

$ dmesg | grep rt2870sta
rt2870sta: module is from the staging directory, the quality is unknown, you have been warned.

The kernel version is

Code:

$ uname -r
2.6.27.19-3.2-pae

I am using opensuse 11.1 and my motherboard is P5E3 Premium.

This module rt2870sta is loaded at boot, but i can`t found any configuration file that i can use to configure this card. In yast it doesn`t show this card, i have tried to add it by my self but no luck.

Here it is the info about the module:

Code:

If you need other information i will post.

**bobescalin2005** · 03-26-2009

What i found recently is a new driver version 2.1. The driver that i use now is 1.4.0.0 as you can see in the modinfo.

Another thing that i found in the README driver is

Code:

Features:
==========
   This driver implements basic IEEE802.11. Infrastructure and adhoc mode with 
   open or shared or WPA-PSK or WPA2-PSK authentication method. 
   NONE, WEP, TKIP and AES encryption.

so it`s support ad-hoc mode

I will install the latest driver i will tell you what i have done.

Cheers!

Please post the output of this command

Code:

lsmod

It will show all modules loading on your system.

Your wireless is supported by the rt2x00 family of drivers. More specifically the rt2800usb driver. This is a relatively new driver, and may not be fully functional, yet. You can try the latest version from the GIT repository, but it looks pretty complicated.

Rt2x00 GIT instructions - Rt2x00Wiki

You could instead try the Ralink supplied driver. I believe that is the one called rt2870sta.

Ralink Technology: Linux

You could also install the latest compat-wireless package, from the Linuxwireless.org site. This is most likely the easiest option.

Download - Linux Wireless

Before doing anything, have you tried changing the mode to Master?

Code:

iwconfig ra0 mode Master

or this

iwconfig ra0 mode Ad-Hoc

Edit: I see you posted while I was writing this, so I see that you know about the ralink driver. Make sure you also download and install the firmware.

**bobescalin2005** · 03-27-2009

I installed the latest version, and i use this tutorial. It seems to be working but i have not tried to connect to a wireless network. I will try this days.

The firmware doesn`t let me to install it.

Code:

./rt2870.bin 
bash: ./rt2870.bin: cannot execute binary file

i made it executable first.

Now how can i bridge those to connection my wireless and my ethernet? Is there any command to bridge two networks?

Cheers!

**waterhead** · 03-27-2009

I think that the Ralink driver may already have the firmware included. The firmware file is not "run", but simply copied to the /lib/firmware folder.

I never attempted to do what you are trying, so I can't help much.
