As far as I understand, it looks like your AP isn't answering DHCP requests. Perhaps DHCP settings on the AP are misconfigured? Perhaps the DHCP address pool is too small? There are also de-auth frames, which means the AP could be trying to kick your zyd0 device off the wireless network. Is your AP using a mac address filter or something like that? It looks like the wifi communication itself works fine. Try the zyd device with a different AP. If that works, chances are your AP is not configured correctly. (For the future: Judging from the timestamps you ran the tcpdump commands in sequence. If you run them in parallel, i.e. in 3 separate terminals at the same time and show lines from all three from the same time frame correlating data from the different layers would be easier.)
