My Nexus One cannot connect to Wi-Fi being broadcast by a Windows 7 laptop My Android (Google HTC Nexus One) is not detecting Wi-Fi being broadcast by my Windows 7 laptop. However, my iPhone can detect the laptop's network. Why is that?

Is there any solution for connecting my Nexus One?
It sounds like you're trying to broadcast a wireless signal using your laptop so that your mobile devices can connect to it. If you set this up via the standard Windows 7 networking tools it would have created an ad-hoc network, and Android does not support ad-hoc connections out-of-the-box.

You can, however, use a "softAP" (that is - software access point) to broadcast a signal as an AP instead of in ad-hoc mode. Connectify works great for me, and I would recommend giving it a try. A list of their supported wireless cards can be found here.

Additionally, you can try to "enable" ad-hoc networking on the Nexus One using the steps described in this forum thread. These steps will require that you have rooted your device, however.
