Wireless Networking help

Just installed archlinux on my laptop at my university. I installed all the network drivers and got the wireless to work. I've come home for the weekend and the wireless card refuses to work correctly. My router is the D-Link AirPlus G DI-524 Wireless Router and my wireless card is the Intel Wireless WiFi Link 4965AGN. It seems to me there is a problem with the default, however adding the default route does not fix the problem.

-router ip is 192.168.1.1 netmask 255.255.255.0
-I used 'dhcpcd' to get an ip from the router which works fine. Shows up the in the router that the ip was leased to my computer. 'ifconfig' shows the same ip as the router says was leased.
-'#route' acts weird. Takes 30 seconds for it to execute. Displays the first entry immediately, but the default route takes a while to come up.

Here is what happens:

#ping -I wlan0 192.168.1.1

PING 192.168.1.1 (192.168.1.1) from 192.168.1.102 wlan0: 56(84) bytes of data.

...

--- 192.168.1.1 ping statistics ---

Some info that may help:

I tried using the ethernet port and it works fine. 'dhcpcd' set everything up and i did not have to modify the route table.

Any help would be appreciated...
Thanks

not much of an expert, the following is the output of arp on my machine, hopefully of some help. was the router powered down while you were away; if not might be worth doing a power cycle.

not addressing you issue really but it does sound like your worried bout security
you could turn off broadcast of essid in DI-524
then set up wep/wpa so that not only does antone in nieghborhood trying to pick off your connection
has to figure out essid then crack your wep/wpa

...just a thought , & maybe you didnt think of it, or was unaware your router could hide your wireless
also if you havent done it setup password for router
if by chance your router doesnt offer to hide it you may need to upgrade firmware of router
just make sure you get correct firmware

for older firmware i found this

I updated the firmware this morning and it did not fix the problem. This is really annoying me since everything is setup correctly. I have no idea why it is not working. Also, i tried adding an entry to arp using 'arp -s'. No luck with that either. It seems that the machine is not sending packets out. Im almost certain it has something to do with the default route, but im not sure what it is since 'route' displays the correct routing table.

as i said before i was really addressing your issue just giving an alternate solution if you wanted it
i know a while back arch had some problems with wep i cant say if it was resolved
you may want to search/ask if this is still the case
post out put of
"iwlist wlan0 scan"

I am not sure about your router, but you can check if Access Control Lists are enabled in it.

Sorry if this is irrelevant, but I use D-link 624 - I think D-link router default is 192.168.0.1
