Unhappy a/p connected, route correct, ping router: "Destination Host Unreachable". DebianEtch


Hi

All the config seems correct but pings (and everything else) fails. I know that everything should be working because sometimes it does and sometimes it doesn't. When it's working, it works well and doesn't stop working (until unplug card, or suspend etc.). When it's not working, I can't get it to start!

I've googled and searched this (and other forums) but haven't found anything that's helped. (it's not a firewall problem, I've rebooted the AP etc., the PSK is fine (because it connects sometimes)) Any new ideas?

Thank you!

you might try disabling IPv6. If you noticde when you done the ifconfig it showed that was running. You can change this in the modprobe file and reboot the machine. I know I have problem at first with IPv6. Hope that helps.
