    I'm using static IP and static ARP and restrict unlisted machines. When a wifi connect I can se that in divice list but when a LAN-client connect I can't se that can only assume it's connected and lease time is counting down. Have I missed something?
    When using static IP I feel web-gui is faster or is't a delusion? :jester:

    They are in static DHCP/ARP list and I can se them in WOL as (Active in ARP) don't follow you to put them in "wireless client filter" under basic menu.

    did you check in device list the mac address and ip address of your lan client is ok .

    When you said that you have "Static IP" do you mean that the IP is entered into the client's configuration for the LAN or Wireless card?


    Static IP = an IP entered into the client machine's configuration for it's LAN or Wireless card.

    Static DHCP= a fixed IP always issued to a client by the router's DHCP to a MAC address requesting access.

    Static ARP or ARP Binding = a method of preventing a client gaining access to the router using any other IP address, as the assigned IP is bound to the MAC address of the client.

    If the client you mention has a "Static IP" - i.e. one not issued by DHCP - the client already has an IP address so it did not request one from the router. Therefore there will be no lease.

    Yes in device list all mac and ip adress is ok there.
    I have added all mac wifi and lan to Basic:Static DHCP and enabled, Enable static ARP and Restrict unlisted machines. Problem is that I can't se if a LAN-client is "connected" or not. wifi is easy, then you have rssi, quality and tx/rx rate to look at. But when a lan-client is "connected" then you can't se if client is connected, nothing to look at.

    If that's important to you, then use the restrictions list instead of the static ARP exclusion method. The at least you can see from the WOL (=ARP) list that that client is (or was recently) switched on. Otherwise, you can usually tell from the QOS/details or webmon lists. Incidentally, the lease time counting down doesn't mean the client is still connected, only that it had a lease which hasn't expired yet.
