    Re: HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc.

    Hi,

    I've recently had to rebuild my machine and I'm unable to get the wireless card working. I've previously had it working using the RT2870 drivers and WPA using the instructions on this and another thread which provides info on how to get the drivers working.

    For some reason this time around I just can't get the wireless working properly. As requested by the OP, here are my files for inspection:

    The interface seems to get the static IP given to it and it sees the AP, I thought that it might be a dns problem as it can't resolve anything, but it also doesn't connect via IP addresses. I tried connecting using DHCP and it fails to get a lease, so my guess is that the interface isn't connecting and something in the wpa_supplicant is breaking (confirmed I guess by the wpa_supplicant daemon failing on startup). What is breaking though I don't know, and I'm pretty sure that I have done nothing different since my last working build (which was a few days ago).

    Oh, just thought I should add that I've tried various combinations of WPA/RSN and CCMP/TKIP with the interfaces config. The AP seems to support WPA 1 & 2 and CCMP and TKIP on the pairwise. The current config is what was previously working.

    Thanks in advance for any help

    Re: HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc.

    Hi daniel.pool,

    Two things... What happens when you ping your router after trying to connect?

    Second, can you connect when all security is turned off? And what about WEP security, does that work?

    I tried setting up an open network and interestingly this didn't work either. The information came up exactly as before but I wasn't able to connect through. I hadn't tried this earlier because I'd gotten it working on WPA before and was sure it was something in config I hadn't done right ... looks like it might be a driver issue instead if I can't connect full stop

    Hello,

    Alright, that's what you have to work on then. You are close, but you need to fix your adapter first before we go ahead. Please open a new thread and feel free to post the link here.

    Hey,

    I downgraded the driver version from the 2.2 version to the 2.1.2 that I would have used a few months back. It appears that the latest version is broken. I've posted on the ubuntu support thread for the ralink 2870sta adaptor that I use and will see if I can raise a bug report with ralink themselves.

    The wpa_supplicant stuff connected straight off once the driver was replaced, though I still get the occasional message that wpa_supplicant daemon couldn't start even though the connection is working fine

    Code:
    root@HTPC:/home/htpc# /etc/init.d/networking restart
     * Reconfiguring network interfaces...
    wpa_supplicant: /sbin/wpa_supplicant daemon failed to start

    This is a bump for my last post in this thread (#1750). Has anyone got any thoughts?

    I would suggest you search for posts relating to your device.

    Essentially, some people found it works out of the box, some didn't. It worked better with the serialmonkey drivers in general than the default legacy ones. The serialmonkey drivers are now in the Jaunty kernel.

    Re: HOWTO: Wireless Security - WPA1, WPA2, LEAP, etc.

    Thanks for the tip Ugm6hr. I did a bit of further research as suggested. From what I gather the ealier versions of the serial monkey driver that were incorporated into the Hardy kernel were by their own admission a bit buggy.
    I didn't fancy installing a later version of that driver. Too much hassle every time there is a new kernel. So I did a fresh install of Jaunty instead. Wireless with WPA worked straight out of the box. I've almost finished getting things the way I want them. Just one or two issues with some web sites in Firefox. But that's a job for another day.

    serialmonkey drivers finally contained in the jaunty kernel -- wow -- its about time. Thank you to whom ever made this happen!!! Can't wait until the release date!!!

    I tried following the steps for WPA1, static IP address, but I can't seem to get it up and running. I'm fairly new to this stuff and I'm running out of ideas. I think it might have to do with the Ethernet interface because it says "*-network DISABLED", but I'm not sure.
    The system that I'm trying to get the internet to work on is Ubuntu Studio 9.04, and the weird thing about it is that I can get my other partition, Ubuntu 9.04, to get wireless access except for that one.
