Aleksandar's computer workshop

Let's see what Aleksandar was fixing today.
My findings, tips & tricks related to computers, internet, programming and other stuff I was working with.

inSSIDer is (much better) replacement for antient Netstumbler

inSSIDer is an free, award-winning Wi-Fi network scanner application for Windows Vista and Windows XP.
It scans networks within reach of your computer's Wi-Fi antenna, tracks signal strength over time, and determines their security settings (including whether or not they're password-protected).

NetStumbler, the most popular Wi-Fi network scanner, is free, but it hasn't been actively developed for years, and it doesn't work well with Vista or 64 bit OS.

inSSIDer, on the other hand, works like a charm on both Vista and XP, 32 and 64 bit, and it's open-source.

This must-have for hunting down Wi-Fi networks on the road.


  • Works with internal Wi-Fi radio
  • Wi-Fi network information (SSID, MAC, data rate, signal strength, security, etc)
  • Group by Mac Address, SSID, Channel, RSSI and "Time Last Seen."
  • Graph the strength of received signal in dBm over time
  • Filter access points in an easy to use format.
  • Highlight access points for areas with high Wi-Fi concentration.
  • Open source (Apache License, Version 2.0)


How to fix Vista Multi Booting, HDD Cloning, drive letter and other boot problems

Today I had to migrate data from one HDD to another. Afected computer have XP and Vista in dual boot configuration.
In normal situation if booted with XP you will see only C: drive while Vista partition is hidden.
When booted with Vista second partiotion is visible as C: and first (XP) partition is D:
HDD was cloned using Acronis True Image 11 Home Edition. Due to fact that HDD was bigger than older one partitions size changed as well.
Everything worked perfectly until old HDDD was taken out and cloned HDD was used to boot from.

First boot XP was working perfectly. Visible is only C: drive and second hidden partition.
But after booting Vista I got some strange errors caused by drive letter change. Vista partition is now D:!

In order to fix the problem I have used "Drive Letter Problems" section from this page:

After few registry entry changes, PC is restarted and everything works!!! GREAT!

I would higly recommend the article for following issues:

Dual/Multi Booting With Vista
Cloning Vista
Possible partition issues
Preparing the BCD
Curing drive letter allocation problems
Fix the BCD while working from another OS or the Vista DVD
Hibernation issues
Backup the BCD
Whole drive cloning


NetStumbler under Vista?

You don't have Netstubler with you or it does not run on your Vista notebook?
For quick and dirty situations you can do bit of war driving with Vista, too!

Go to a command prompt, type
netsh wlan show networks mode=bssid
You will get all available networks with enough details mostly not available in Vista GUI.

It looks like this:

Other alternatives are:

Vistumbler is a netstumbler like program for Vista (or later...maybe).

* Find Wireless access points - Uses the Vista command 'netsh wlan show networks mode=bssid' to get wireless information
* GPS Support
* Export/Import access points from txt file
* Export access point GPS locations to a Google Earth KML file
* Open Source ( AutoIt Scripting Language - )
* Change column order, column title, and column width in the 'vistumbler_settings.ini' file
* Change search terms in the 'vistumbler_settings.ini' file. This means Vistumbler should be able to work with other languages. Change searchwords to what they are in the another language, Search terms can be found by running 'netsh wlan show networks mode=bssid' in a command prompt

Inssider is a Wi-Fi network scanner for Windows Vista and Windows XP. Although NetStumbler, the most popular Wi-Fi network scanner, is free, it hasn't been actively developed for years. We heard complaints that NetStumbler doesn't with Windows Vista and 64-bit Windows XP, so we decided to build an open-source Wi-Fi network scanner designed for the current generation of Windows operating system.

* Works with internal Wi-Fi radio
* Wi-Fi network information (SSID, MAC, data rate, signal strength, security, etc)
* Graph signal strength over time

Windows Vista Battery Saver

Some rumors are saying that AERO interface is draining the laptop battery due to intensive GPU usage.
There is small utility which "optimizes" the Vista options. Does it really works on your laptop you have to test yourself.
Here are few articles related to this issue:
