OK, I've been ponderign this a little bit. Sorry, maybe too little as you'll
soon see....
1. Wireshark. This program is your friend. Use it, love it, and save
yourself a ton of grief. You can see all the packet flow with it.
2. If I recall correctly, this isn't your first dance with the laptop and
the router. Youv'e had issues before.
3. Why use static IP addressing? Unless you are using something really
legacy (Windows 98) on a machine, you should be able to let it just
automatically pull an address from the DHCP server. One mistake many people
make is manually setting the IP address of a host (computer) to an dynamic
address. When you attach another host device to the network, you can end up
with a conflict. Nearly everything these days, including network printers,
are designed to work with DHCP. Static IP addressing gains you essentially
nothing and should be used ONLY if DHCP doesn't function for a given device
and ONLY for that device.
4. The Ethernet cable to the laptop may be bad.
5. Let's double check which ports on the router you are plugged into. There
is one uplink port which connects to the DSL modem. Then there are probably
four or eight ports for the computers (hosts) to attach.
6. Double check that you don't have a DMZ setup on one of the ports or IP
addresses. This would place that device on the outside of the firewall,
which explains why you can ping the router, but not the other computer and
why the other computer can ping this one.
7. You have turned the WiFi OFF on the laptop, right? If it's still on AND
plugged in, you are probably actually connected to two different networks.
It is responding to pings from the other computer, but when pinging from the
laptop, the preferred path is through the WiFi connection which may be
coming from your neighbor's router.
