Wireless via PCI Adapter [Solved]
« on: January 20, 2012, 02:15:19 pm »

I have just installed a PCI wireless adapter on a system running Vector Linux 7.0.
Running the same machine from a Parted Magic Live CD, it works perfectly but
under VL 7.0 it doesn't even appear to be detected. Am I missing a driver module?

Yesterday when I ran lspci there was no reference to the Ralink device. Same on lsmod. When I booted up today to run them in order to reply, there was. I did a search on Google for my own website and up it came. I cannot imagine why this should be. So sorry to have troubled you and thank you for taking the trouble.

I spoke too soon. I had forgotten that last night I had plugged an Ethernet lead in to make contact and of course that was still in when I ran Parted Magic! (Idiot!).

So back to square one. Attached are listings from lspci and lsmod.

I have since booted up on PCLinuxOS liveCD and successfully logged into the wireless network, so the hardware is indeed fine. It must be down to the way I am setting up the connection. On the laptops I only seem to need the ESSID, selection of WAP and insertion of the shared key. I have done that here but it doesn't do the trick.

The Wicd Network Manager preferences has the Wireless interface as etho. Everyting else is set to defaults.

Heh, been there, done that. It's how I learn. ;)

Your problem may be that wicd is not set to look at the correct interface. It defaults to "wlan0", but your device may be named "ra0". In a terminal, as root, issue command "iwconfig" and look for it. Then make sure that wicd preferences are correct.

According to iwconfig, wlan0 comes up reporting IEEE 902.11bg, my ESSID and several other bits, one of which is 'Encryption key=off". As I had entered a WAP pass pass phrase, that looks decidedly odd.

Using vasm I managed to get the system to recognise the wireless network but when I try to 'connect' I get 'Connection failed: Bad password'.

Frustrated, I decided to cheat (I know). I copied the network settings from the wpa_supplicant.conf file on my Asus PC901 netbook. I also made sure that the target computer's MAC number was included as an 'allowed' accessor on my wireless router.

After restarting both the router and the target machine, I still have the same problem.

Here are the contents of iwconfig and ifconfig -a

ok...from your ifconfig/iwconfig your wireless adapter is assigned as wlan0...check WICD to use wlan0 and try use WICD to connect to your network...

As far as I could see, one cannot set the interface in WICD, only in vasm where it was already set to wlan0. Can I assume that the WPA_supplicant is correct?

Anyway, Wicd is reporting my network name, -42dBm, WPA and Channel 11. It just will not connect. The problem seems to me to be a mis-match in protocols

My adapter uses a Ralink RT2561/RT61 device, so I used -Dralink in my wpa_supplicant command.

Properties are defaults except for 'Use Encryption' which is ON, WPA 1/2 (Prshared Key) and the key itself.

Left-click the wicd systray icon, maximize the resulting window and look for the Preferences icon right below the title bar.

I am using VL 7.0. The screen has an icon ribbon at the bottom and a menu bar at the top. There is no WiCD icon in the ribbon at the foot and right-clicking on the icon at the top offers: connect, connect info and quit!

Wherever you right-clicked, do a left-click instead.

Or, Menu > Internet > Wicd Network Manager

If the wicd window is not big enough to show the Preferences button, look for a little down arrow in the upper right quadrant.

Sorry, unfamiiarity with VL. The down arrow did it. I changed the interface to 'wext' and lo and behold, it worked like magic. Thank you for your patience. I almost gave up. I'll now put VL on my netbook as well. Thanks again,  Alan
