forcing re-issue of ip addresses from router

[whburling]

I currently own a wrt54g wireless router from linksys.

It has a built in DHCP server.

I can issue a command to delete the DHCP table.
The command works.

However, I can not force the DHCP to re-issue ip addresses to
all the machines on the router which were in the table before
I deleted them.

There must be a logical reason why the DHCP server can't re-issue
the IP addresses.

Can anybody help me understand why?

I am aware that I can go to each machine and issue a renewal of
an ip lease using ipconfig in win2k and something analagous in
imac.

any help will be appreciated.

DHCP protocol is governed by various RFCs. The basic process is always
initiated by the client not the server, and has changed little since its
inception:

In your case the client machines already have IP addresses. Deleting leases
on the server does not remove those addresses; and clients will not
automatically request renewal until 50% of the original lease duration
period expires.
