LinuxQuestions.org - Wireless card stopped receiving packets

hello world!

I just installed Slackware 13 with xfce and everything went well (eventually). At first, my wireless didn't work, but then I found /etc/rc.d/rc.wireless.conf. Everything was working, and I was happily surfing and downloading packages.

But then one day... It just stopped! I tried to ping google, and it could send packets but not receive them.

There is no encryption on the router and it uses DHCP.

It's not a hardware issue since Ubuntu can access the network just fine.

Here is my iwconfig output, although I don't think it's of much use. I know it says link quality is 0, but even if it's positive, I have the same problem.

eth1 IEEE 802.11g ESSID:"merakisecundus" Nickname:"slackware"

What's going on?!?! help please!
