Switching between 2 DHCP Networks - How?

[Guest]

Hi,

This is the scenario, we have a Company LAN and you are allocated an IP via
DHCP, we also have a Wireless LAN within the building which also allocates
addresses via DHCP (different subnet).

Our Centrino Laptop Users sometimes need to come off the Company LAN (wired)
and go into meeting rooms and use the Wireless LAN, currently they have to
reboot or do "ipconfig /release and then /renew" switch between networks.

How can I do this without rebooting? I would like to maybe have 2 icons, one
"LAN to Wireless" and the other "Wireless to LAN" which would run a script or
batch file to try and automate this.

Any ideas?

Thanks very much

Use Alternate IP Configuration under TCP/IP properties.

Would I get a problem that the machine could constantly be switching from LAN
to Wireless if a wireless signal was present when you were physically
connectecd to the LAN?

What I think I need (but am open to any suggestions) is a neat,slick and
manual method of changing from one network to the other.

Thanks

Trev,

What's wrong with scripting:
"ipconfig /release"
"ipconfig /renew"

I do just that to move my computers between two routers.

Hi Chuck,

I can see that would work going from LAN to Wireless but not the other way
around as the DHCP requests could be answered by either the LAN or the
Wireless network.

The problem I have is trying to make this a "one click" solution for both
directions, bearing in mind senior management like pretty icons that do the
job rather than them having to have a modicum of technical understanding. I
like your idea for though.

Trev,

It should work both ways. With automatic metrics, Windows XP should use a wired
connection whenever it's available, since the wired connection is faster.

If you want to use two icons (ie "Switch to Wired" / "Switch To Wireless") you
could script disabling / enabling the wireless connection on the computer with
the "netsh" command. That would probably be a good idea from the security
perspective too, as you should have your wired and wireless LANs separated as
much as possible.

Unless your office is in the country, with lots of airspace between the public
and the office, you should consider your wireless LAN less secure than your
wired LAN, and discourage any computer ever connecting to both at the same time.
Disabling the wireless connection, whenever connecting to the wired LAN, would
be a very good idea.
