Exactly - most gateways use the first usable address as a gateway, like .1, so are you really sure your router is .5? That is... abnormal.

Traceroute 68.2.16.30 (cox dns server) to see what the deal is. Really seems you're not getting to your gateway, so it'll die at .5. Ping .5 address too, is it there?

Try dhcp, static is not a requirement really as long as your dhcp/router is stable. It's not windoze server here, should be alright.

If dhcp is handing out .1 as its gateway and you assign .5 manually you
would have good internal connection but no route to the Internet.

    Sorry, Michael, I am a little lost.

    i changed the gateway entry in my /etc/network/interfaces file to be
    192.168.25.5. Are you talking about something else? I am only trying
    to connect over the wired network from my laptop to the Internet,
    with a fixed IP. My interfaces file has the following (the comments
    are the old values):

    auto lo
    iface lo inet loopback

    # The primary network interface
    iface eth0 inet static
           address 192.168.25.150
           netmask 255.255.255.0
           gateway 192.168.25.5
           dns-search ph.cox.net <http://ph.cox.net>
           dns-nameservers 68.105.28.12 68.105.29.12 68.105.28.11
           #gateway 192.168.25.1
           #dns-search tc.ph.cox.net <http://tc.ph.cox.net>
           #dns-nameservers 68.2.16.25 68.2.16.30

    Thanks!

        Did you update your default gateway to be .5 instead of .1 for
        the dhcp scope handing out to clients?  If your gateway is still
        pointing at .1, or your dhcp gateway is handing out .1 where
        your router/gateway is .5, that would do it.

            I just received a new ASUS RT-N16 running dd-wrt from
            Flashrouters. I
            replaced my aging Linksys BEFSX41. The only change I made
            was to the LAN
            IP - the router comes setup with 192.168.1.1, and I changed
            it to
            192.168.25.5 (my network is 192.168.25.xxx). I connected the
            new router
            to Cox through my cable modem, got a new DHCP WAN IP and new dns
            nameservers. I updated my
            /etc/network/interfaces to reflect the new
            dns nameservers,
            dns-search (changed from tc.ph.cox.net
            <http://tc.ph.cox.net> <http://tc.ph.cox.net> to
            ph.cox.net <http://ph.cox.net> <http://ph.cox.net>), and

            the gateway from 192.168.25.1 (old router) to 192.168.25.5
            (new router)
            (I use a fixed IP on the wired network, and DHCP for the
            wireless)

            I can connect to the Internet using the wireless part of the
            new router,
            but the wired part of the new router times out on access to the
            Internet. I can ping all my local machines on the wired
            network. When I
            ping google.com <http://google.com> <http://google.com>, the
            error is ping: unknown host
            google.com <http://google.com> <http://google.com>, so I
            assume I cannot resolve any

            Internet addresses.

            Any suggestions on how to further troubleshoot/fix this problem?

            Thanks, and Happy Good Friday to everyone!
