Post Ad-hoc setup with Ubuntu 9.10
Hi all,

I got some problem with the ad-hoc setup for my fit-pc2 with ubuntu 9.10

I used to have ubuntu 10.04 installed on my fit-pc2, and wireless did not work, so I switch it down to 9.04 and followed the instruction on the website. The infrastructure wireless seems working very good on my machine now. (connecting to internet)

But when I am trying to create a ad-hoc wireless network with multiple fit-pc2s, it doesn't work now:

1.) when I use another laptop to create a ad-hoc, and I use fit-pc2 to connect to it, the system keeps asking me for "Authentication required by wireless network".

2.) when I try to create a ad-hoc host on my fit-pc2, it ask me for the same thing!?

Basically, the fitpc2 can connect through my router to internet, but it can not create or connect to ad-hoc.

Is there some hardware issue or driver one? I saw some posts discussing about similar issues, but I am a bit confused there.

Chris

For lucid use the ppa at [1]. AdHoc mode is a driver issue. I don't know if this driver supports it.

Thanks for the reply fly.

I follow the instruction in [1]

But when I use

sudo lshw -C network

to check my wireless card configuration, below is what i got:

*-network
description: Wireless interface
product: RT3090 Wireless 802.11n 1T/1R PCIe
vendor: RaLink
physical id: 0
bus info: pci@0000:03:00.0
logical name: wlan0
version: 00
serial: 00:0d:f0:6e:2d:77
width: 32 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=rt2860 ip=192.168.1.100 latency=0 multicast=yes wireless=Ralink STA
resources: irq:17 memory:d0200000-d020ffff

I do not understand why the driver still says rt2860

Is this the problem?

Sincerely,
Chris

Using the driver mentioned by [1] in lucid should return:

Quote:
configuration: broadcast=yes driver=RALINK WLAN driverversion=2.3.1.7 ip=192.168.23.32 latency=0 multicast=yes wireless=Ralink STA


I don't know how 9.10 output should look. However, rt3090 driver shares quite some code with rt2860. The default linux driver for rt3090 is indeed the rt2860, see kernel log at [2]. Try blacklisting rt2860 and then modprobe rt3090sta.

--edit--

Looks to me like you are not using the ppa-version of the driver. Did you just add the ppa or really install the driver? After adding the ppa to your software sources you should run:

Code:
sudo apt-get update && sudo apt-get install rt3090-dkms

Thanks a lot, fly

I did everything including modprobe rt3090sta, But I forgot to blacklist rt2860sta

Everything works well now.
