are no longer transferred (ping to Access Point (Linksys WRT54GL) no longer
works). Even rebooting does not help. As hardware I'm using

Kernel running is 2.6.27.21-0.1-pae. IIRC when disabling secure encryption (WEP
or no encryption at all) the issue gets fixed, but this is not what anybody
wants ...

Which other information do you need to look into this issue?
