Everything is working (wifi out), but arch pc is not pingable

Question

Hi there!
Please excuse any formal errors, this is my first post here. I tried to find some
helpful post in the forum but didn't get anything helping me with this situation.
Setup: Router(Fritzbox), Windows 7, Arch,....
On my Arch I have a RealTek 8192CE wifi module, which I got working very well
by disabling ips and fwlps)
Workin right now on the Arch and wifi is just working fine, but there is no chance
to get pinged by other machines.
My Settings:
(wicd is doing the wifi connection)

What I know:
Until yesterday everything worked (could be caused by the install of the samb
server, but no hints in what way it could be the culprit)
tcpdump shows no incoming or failed transfers for ping or ssh attempts from other
units in the local network.
The error from outside is a "connection time out"
The router does not receive the hostname (I suspect this being essential since the
showed up before)
What I'd like to know:
Where can I search further, what log files should I go through?
Thanks a lot!

Edit:
While browsing there are interesting entries in tcpdump:
ARP, Request who-has 192.168.178.34 tell fritz.box, length 46

Answer 1

Figured it out by myself, there were invalid ARP entries, due to an old firmware on the second access point.
