Competition isn't always a good thing.

You don't want to compete with your neighbors over wireless spectrum. Sometimes there is noise being generated by outside sources. Maybe you just want to position that wireless router just right. Here are your free tools to to give you insight to that invisible world of 802.11.
inSSIDer is an award-winning free Wi-Fi network scanner for Windows Vista and Windows XP. Because NetStumbler doesn't work well with Vista and 64-bit XP, we built an open-source Wi-Fi network scanner designed for the current generation of Windows operating systems. inSSIDer was discussed by Lifehacker and Tekzilla!

These are my 2 wireless routers.

Here I am with my neighbors. I actually have my signal strength turn down to limit the range my networks can be picked up. You can see the fluctuations in my neighbors signals since they are transmitting a much greater distance.

Here is a capture of MeteGeeks chanelizer lite

We realize these don't look like inSSIDer reviews, but we've clipped them and you should be able to jump straight to it when you click play. Enjoy!

Not Just Virtually Free

When we think virtualization we think VMware or Microsoft virtual machine. This stuff is never easy and never seems to work out the way you want it. Here is a simpler, easy, and best of all, free solution. This supports most operating systems inside and out and can handle 64bit as well.

I'm still a big fan of Mojo Pak but XP is phasing out quickly.

What they say on their web page:

VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

Some of the features of VirtualBox are:

  • Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
  • Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
  • Guest Additions for Windows, Linux and Solaris. VirtualBox has special software that can be installed inside Windows, Linux and Solaris virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window). There are also guest additions for OS/2 with somewhat reduced functionality.
  • Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines.

A number of extra features are available with the full VirtualBox release only (see the "Editions" page for details):

  • Virtual USB Controllers. VirtualBox implements a virtual USB controller and allows you to connect arbitrary USB devices to your virtual machines without having to install device specific drivers on the host.
  • Remote Desktop Protocol. Unlike any other virtualization software, VirtualBox fully supports the standard Remote Desktop Protocol (RDP). A virtual machine can act as an RDP server, allowing you to "run" the virtual machine remotely on some thin client that merely displays the RDP data.
  • USB over RDP. With this unique feature, a virtual machine that acts as an RDP server can still access arbitrary USB devices that are connected on the RDP client. This way, a powerful server machine can virtualize a lot of thin clients that merely need to display RDP data and have USB devices plugged in.
