How to change IP on wireless network?

[Anima]

Hello,

I would like to change my IP address.

My computer is automatically connected to a wireless network (administration by the hotel building) and so I don't have access to the router.


==

The command ipconfig/all gives:

IP Routing Enabled: No
WINS Proxy Enabled: No
Dhcp Enabled: Yes
Autoconfiguration Enabled: Yes
IP Address: ....155
DHCP Server: ....237
Lease Obtained: 1/6/2009
Lease Expires: 1/7/2009 (1 day lease)

the IP address from whatismyip.com is: ....124


==

I have tried the following:

command prompt, ipconfig/release, ipconfig/renew protocol

changing the 'IP/TCP' in Properties for the wireless connection protocol

switch wireless off/on on the computer, disable/reenable connection, and 'repair' for the connection

connecting to another wireless network then reconnecting to the primary one



===


But the IP address is still ....124



===

How can the IP address be changed?


Is there any service that can do this?




Thanks in advance for your help!!
