Improve Wireless Connection Latency With WLAN Optimizer

An annoying feature that computer users persistently have to deal while playing online games is signal strength issues. One is likely to face the same even while chatting and browsing. These problems occur due to latency lags, i.e. time taken for a specific block of data to reach from the source to its destination. WLAN Optimizer, is a portable freeware application that tries to defeat these troubles.

The application is programmed to enhance latency of wireless connections. It attempts to do so by disabling the periodical background scan activity for wireless networks which tend to cause major lag on some system.

The portable freeware lets multiple devices share information through a central device, typically a wireless router. In most cases, this router is connected to the Internet. In order to ensure your wireless network stays optimized, you can choose to Start WLAN Optimizer with Windows. Closing WLAN Optimizer restores Windows standard values.

The utility can be launched from the system tray. When launched, the tray icon displays the selected device’s state (blue when connected, else grey). You can toggle auto configuration, background scan and streaming mode, to optimize your wireless network according to your requirements.

How to install WLAN Optimizer

  1. Download the program zip file,
  2. Extract the contents to a desired folder
  3. Run WLAN Optimizer executable

By default, WLAN Optimizer comes activated with ‘Disable background scan’ option, which can be found under ‘Tweaks’ in its settings. If any improvement with disabled background scan tweak is not visible then you can enable the streaming mode. Remember, when you’re connected to network, tray icon appears in blue color otherwise it is in grey color.

WLAN Optimizer contains the following tweaks:

  • Disabling autoconfig (admin rights needed)
  • Disabling background scan (no admin rights necessary)
  • Enabling streaming mode (no admin rights necessary, but driver dependent)

The user can choose which tweaks to use. However, it is recommended not to disable autoconfig. If disabled, you won’t see any networks in Windows.

WLAN Optimizer is compatible with Windows 7, Windows Vista and Windows XP and can be downloaded from here.

    Okay, as always thanks for the tip. However, as always before downloading & installing new apps willy-nilly, I went to the developer’s website to see what they have to say about it. If you view the results of their Poll page (, this app has not been such a great benefit to users. Click on the the Results at the end of each Poll questions to see for yourself. I am willing to give this ap a try but have low expectations. That’s my 2 cents. Good luck.
