I would not refer to a computer as a router
just because it is running dhcpd.
I was referring to the WRT54GL, as I think was obvious
since I said "my WRT54GL router".
The problem with this device is that it sometimes loses WiFi connection.
Many other people with this router have said the same thing.

On the laptops and other devices (camera, TV, smart phones)
behind the router.
The CentOS server continues to work.
And I can access the router web-page from the server.
That is why I was asking if there is any way
of getting the server to "wake up" the router.

Actually, I can still ping the router (from the server)
even when it has lost WiFi connection.

The problem is in the router.
Everything else works fine.
Also the problem is easily solved by disconnecting and re-connecting
the router.
The difficulty with this is that the machine is in another country.

There is nothing relevant in /var/log/messages on the server.
On laptops and phones there are the messages one would expect -
eg NetworkManager says at great length that it has lost connection.

The server is an HP MicroServer,
The ethernet card on the router link is Broadcom NetXtreme BCM5723
(according to lspci).
