    I have a device on my home network with a static IP address of 192.168.1.24. If I plug my computer into one of the LAN ports and the device into another LAN port, both on the pcWRT, and then try to ping 192.168.1.24 it does not find the device and it says its pinging a different IP address (Reply from 192.168.1.102: Destination host unreachable). The same thing happens when the computer and device are using the pcWRT Wi-Fi.

    If I type http://192.168.1.102 into the address bar of my web browser it opens the pcWRT web page.

    If I plug my pc and the device into the LAN ports on my 2-Wire router or use the 2-wire router Wi-Fi then I am able to ping the device.

    The pcWRT has the default settings it was shipped with (parental controls disabled).

    The device works when plugged into the 2-Wire router but does not work when plugged into the pcWRT. The device is a dataprobe iPIO-8 http://dataprobe.com/ipio.html

    The pcWRT LAN IP address defaults to 192.168.10.xxx. So if you connect a device with IP address 192.168.1.24 to it, they cannot communicate.

    I assume that your 2-Wire router uses the 192.168.1.xxx address range. If that’s the case, the pcWRT router cannot use that address range. The default address range 192.168.10.xxx works. But that means if you connect your device and computer to pcWRT with static IP addresses, you have to assign IP addresses from the range 192.168.10.2 – 192.168.10.99. The upper limit of 99 prevents IP address conflicts with IP addresses assigned by the router’s DHCP server (i.e., automatically assigned IP addresses).
