[sf-lug] Connectivity problem

Here's a configuration problem I don't understand.
The network is as follows:
Internet comes in as a fixed IP on the external interface of a Linksys
WRG54G(v6) router with settings all pretty much at defaults.
Its internal interface has IP 172.24.16.254 serving a Class C
On that network is a DreamPlug with ethernet connected
at fixed IP 172.24.16.100.
This DreamPlug also has a WiFi interface which serves as a wifi Access Point
with fixed IP 10.0.11.1 serving another Class C 10.0.11.0/24 network.
When connected to that access point with my laptop as a client I get
(by DHCP) IP 10.0.11.100 (as I should.)
>From this laptop I get the correct response to the following commands:
$ dig @127.0.0.1 linuxmafia.com +short
$ dig @10.0.11.1 linuxmafia.com +short
$ dig @172.24.16.254 linuxmafia.com +short
$ ping yahoo.com
provides me with yahoo's IP address but the ping does not go through and
the lap top can not make use of the internet.
I can't understand how this could be.
Has anyone any suggestions as to what might be happening or how to trouble
(Thanks, by the way, to Rick Moen who taught us/me on this list some years
ago how to use the dig command.)
