I have the following problem:
Everything worked fine until I updated my Kernel (to the "latest"). Now I think this new version is a lot better for detecting wireless cards and stuff, however my connection was not working. So I tried a few things, but didn't manage to get it working.
I keep on getting the error:
SIOCSIFFLAG: No such file or directory
Determining IP for wlan0.....failed
Probably my configuration is screwed up, because I used another version of Kernel, and now changed,but in the old situation, I manually added my wireless card (using modprobe and things).
Does anyone have any possible solution for me?
More information is needed. Please post your distro, kernel, wireless card type and driver previously used.
Also post the results of this command: or if it's a USB Sometimes when you upgrade to a newer kernel, modules have to be rebuilt. Or, there may be a newer driver that is now conflicting with the older driver.
Network controller: RaLink RT2561/RT61 802.11g PCI
It is a Linksys W54MPG v4.1
olf kernel: 2.6.21-1.3194.
I still need the results of the lspci or lsusb commands. It will tell us what chipset is in the card. That is the most important piece of information.
I only copied this part:
Network controller: RaLink RT2561/RT61 802.11g PCI
That is the information you need right? This is my wireless card.
Sorry, I thought that was the name on the outside of the card.:oops:
It looks like you need the RaLink driver. First, try this command: If you get something with a ra prefix, like ra0, that is your wireless. If you don't see anything, try this:
then try iwconfig again.
Here's some links to sites that I found concerning RaLink cards. If you can't get the driver to load, you may need to install the driver.
Linux install and configure DLink DWL g 520 - RT61 Wireless LAN PCI Card
RaLink RT2561/RT61 802.11g PCI - Ubuntu Forums

Gleaming over these sites, it looks like you may not be able to use WPA encryption, only WEP. We can tackle that after you get the device running.:)
Yes, thanks, but that is basically the problem...
I used modprobe and things to get it working (under the old kernel version). Everything works great (although I do need to type in: ifconfig ra0 up, dhclient ra0 -d & everytime I reboot).
But now I update my Kernel and that new Kernel automatically detects my wireless card, but gives it a different name (wlan0) and even though I can configure that card, it doesn't connect, because it gives the SIOCSIFFLAG error and says it failed.
So I think the problem is that because I manually added the RT61 driver for the old Kernel, the new Kernel is confused because there is a manual install and an automatic install....
It seems that you need to remove the faulty driver module. First you have to determine the name of the unwanted module:
Post the results, I'm looking for any module with the "rt" prefix. They need to be removed, and then blacklisted so that they won't automatically load.
There is another How-To on this:
HOWTO: RT61 on Egdy Eft with WPA - Ubuntu Forums
It also explains how to setup the connection.
Thanks, Output of lsmod:
This is all. I used some similar FAQ to get the connection running under my old Kernel, but the new one is the problem :)

I now installed both Kernels such that I can switch, one with the working connection, one with the connection that needs to work :)
Hopefully the lsmod is of any use!
Following the last link that I posted, it looks like the rt61pci is the bad one.
I gotta go to work now, I'll get back to 'ya later.
