Hi i have been a happy user of arch on my laptop for about 6 months. My laptop's wireless card connects to many routers including coffee shop, school, work, and friends homes. Now internet has been installed at my house and came with a wireless router / cable modem / switch all in one device. I have been trying to get this to work for days now.
Other devices connect to it fine, including another laptop, and several phones. My laptop connects to it fine using Windows 7. Arch can also connect to the same device fine using a wired connection.
On Arch using wireless it connects and dhcpcd will retrieve an IP address and fork to background like normal, but I cannot ping anyone on network, the router, or access the internet.
I have done the following steps:
1. I thought it may have been the encryption so I disabled encryption on the router
2. I saw it was retrieving an ip address in the 10.0.0.* range and all the other networks I use are in the 192.168.*.* range so i changed router to use that block.
Fairly lost on what to do next, hard subject to search for because i find everything in the world except this issue.
Thanks for any help, unhappily stuck in Windows for now.

What kind of router is it and what kind of wireless card does your laptop have?
Edit: okay, you've added the router type ;-) Now what does the following give:
lspci -nnmvk

To be more clear I have renabled encryption since it did not seem to be the issue.
The full output from
lspci -nnmvk
is available here : http://pastebin.com/8W0DsPgG
I think the relevant part is:

Vendor: Intel Corporation [8086]
Device: Centrino Advanced-N + WiMAX 6250 [0087]

Okay, when I look up your router, it only appears to support 802.11n connections, so I searched for the following terms:
"centrino Advanced-N + WiMAX 625" OR "iwlagn" 802.11n
and found this apparently relevant thread.

Defiantly relevant. I will look around myself some more since N seems to have issues
my iwconfig shows N though and still have same issue, that file does not exist in arch, but i did run modprobe with the 11n_disable=0 flag
wlan0 IEEE 802.11abgn ESSID:"HOME-34F8"

Thanks though I have a new area to look around in.
