> It is the router and/or the client that have picket up these signals and misinterpreted them
From what I understand of this attack, the signals are not being misinterpreted. The client receives a packet which basically says "I'm the AP and want you to disconnect", so the client correctly does what the packet asks it to. The packet, however, was spoofed; who send it was not the AP, but someone else.
The solution to this particular attack, as someone else mentioned, is 802.11w, which authenticates these control packets so they can't be spoofed. Unfortunately, it's still uncommon.
