RT61 Problems

I decided to install Arch on another computer of mine, this one has a RaLinkTech RT61 wireless card.
I have had this card working flawlessly in Ubuntu before.
I installed arch, installed drivers, finished the installation, and rebooted.
My internet connection was working fine, so I updated using pacman, got alsa and X working, and rebooted.
Upon reboot, I have no internet access, iwconfig reports the device as working, ifconfig wlan0 up, and ifconfig wlan0 down both work, but there is no terminal output, and no internet connection.
I even reinstalled, but the same thing happened, it worked fine on first boot, but thereafter, no connection.
I can't even ping my router.

Any help would be much appreciated.

Re: RT61 Problems

If I could guess I'd say that you got a new kernel while updating and that for some reason the new kernel doesn't support that card as well as it should.

Check your /var/log/pacman.log and see if you've bumped kernel versions. If you have, sneak a peak into /var/cache/pacman/pkg and see if you can find the old kernel version there.

If you do and want to try and fix this remove the "new" kernel package via pacman and install the "old" kernel package and reboot.

Re: RT61 Problems

Ok, will try in the morning.
Are there any negative effects to running an old kernel?

Re: RT61 Problems

Does iwconfig show an access point?

  Is this the rt61 or rt61pci module? 
  Ihave a linksys card which shows the following from lspci:

     02:03.0 Network controller: RaLink RT2561/RT61 802.11g PCI

  Up until recently I had to remove the rt61pci module that came with the kernel and compile and install the rt61 module.  Whether this had to be done depended on the version of the chipset you had.  After recent kernel upgrades I can use the built in rt61pci module without having to compile the rt61 module.  Your mileage may vary.   I'm using the following modules which should be in the kernel.  They may or may not be the ones you need.

  rt2x00lib              25984  2 rt61pci,rt2x00pci
  rt2x00pci               9344  1 rt61pci
   rt61pci                24704  0

  Are you using netcfg2?  If not install it and check the example directories under /etc/network.d.  The config files are relatively easy to configure.
