      I have 1 wifi client 24x7, and another periodically through the workday.

      The one that is 24x7 is offered and gets a DHCP lease every 3 seconds - exactly, and continually.

      Can I be confident that it's something on the client end causing this? I need to know where to start attacking this, even though it works fine and doesn't drop out, I'd like to fix any problems since this doesn't seem right to me.

      Thanks.

        Lease time is set by the server and the client renews around 1/2 or 2/3 through the lease time. Can you use Packet Capture or Wireshark to see what lease time the server is providing? If longer that 5 - 6 seconds, then there's a problem with the client. If the other device is not also renewing at 3 seconds, then the problem is likely with the client that is.

        I haven't lost my mind. It's around here...somewhere...
