Spoofing Source Mac Works on hardwire Only

[AgentSmithers]

Alright I've written a ARP spoofer in like 3 different languages so far and each have the same issue, They can only spoof on a hardwire, I'm guessing 802.11 has a way to detect/keep track of who is sending what, perhaps in a SEQ number?

Today I hooked up my WRT610N with DDWRT firmware and did a wireless repeater, then connected my laptop to it hardwired then sent the packets and everything worked 100%, Yes the laptop was not wireless but the repeater was, Why DOES THIS WORK! How can a repeater send spoofed packets but not a Laptop?

does the repeater have a special way of sending its data so its not checked by the access point?

Does it use its own MAC and 802.11 header to send the spoofed data and thats why it works?

I can't tell where the data is being filtered, On my Client Side or the recv'ing router, I'm sure its the router, Any enlightenment here?!

The Router always works on layer 3 where as the laptop works on layer 2.

In Layer 3 the transmission takes places as follows,

A router encapsulate till layer 3 where as, laptop normally works on NIC card that encapsulates on Layer 2. So when your are sending the packet from layer 2 to layer 3 (repeater) it strips off the Mac as it has recevied from NIC and puts a new encapsulation for layer 3 and forwards it to the router.

Well at least you got your first post in on code Guru.... Anyone have any information that is relevant to the topic though?
