Or, in most laptops there is an "RF kill" switch for the wireless that can be controlled in software/hardware. You can use it to enable/disable wireless.

I need DHCP and > preferably WPA. iwconfig eth1 mode ad-hoc essid 'sandip' channel 11 (or whatever) Now your laptop is a P2P WiFi AP, and you can connect any other WiFi device that does Ad-Hoc networking with it. Of course, this will only work if the laptop itself isn't connected to an AP (i.e. in Managed mode) -- you can only run it in one of Managed or Ad-Hoc modes at any time.

If you don't prefer masquerading, you can also put your box in bridge mode (i.e. act as network switch, instead of router) and use DHCP server running at modem for allocating IP addresses. I assumed your modem is doing PPP setup and has a DHCP server running. But this will be an overkill, and plus I'm not aware of how this is going to work with network profiles, i.e. disable bridging when not in home network. :) Sandip> I am also not comfortable using static IP even for testing(I understand Sandip> that it eliminates an unknown during testing), as my mobile is Sandip> definitely easier to manage with DHCP. How about IPv4-LL[1] (169.254/16 addresses) using Avahi[2], which works fine in absence of DHCP server. It'll work fine in roaming also. But your mobile phone should be capable of doing negotiation.
