I have a problem with my recently setup print-server (using an old
ASUS WL-500g (using the b43 driver) running a recent checkout of OpenWRT
Backfire). It boots fine, connects fine to the WPA network (in station
mode), but after a while I can't connect to it any more. That's not
because it lost connection to the wifi network, tho, but only because
the ARP request somehow is not answered.
I.e. here's what I see:
- the wl500g has IP 192.168.1.33
- from 192.168.1.37 (some laptop of mine), I do "ping 192.168.1.33"
it says "Destination Host Unreachable".
- I connect a laptop via wired-ethernet to the wl500g, ssh into it, look
at wpa_cli, which says everything is fine. I do "ping 192.168.1.1"
from the wl500g and my router responds just fine.
- at that point, from 192.168.1.37, "ping 192.168.1.33"
still says "Destination Host Unreachable".
- now, back on wl500g, I do "ping 192.168.1.37" which shows that my
wl500g sees my laptop just fine.
- in return, back on the laptop, "ping 192.168.1.33" starts to work
again (finally).
I.e. for some reason, the ARP request from 192.168.1.37 never gets an
answer. I have another laptop (both running Debian testing with
a recentish Debian kernel (2.6.34 or more recent)) on this wifi network
and they seem to see each other just fine without any problem, the
problem is only "from laptop to wl500g".
Does that ring a bell to anyone? What could I try to further diagnose
or fix this issue?

PS: Of course, the unknown element here is the AP which is an ADSL
modem+router based on a Conexant chipset running some unknown firmware,
provided by my ISP :-(
