What is wlancfg5.exe?

The genuine wlancfg5.exe file is a software component of Netgear CUv2 by Netgear.
This executable controls Netgear wireless network cards. It includes a client interface for adjusting settings as well as running in the background to monitor the status of the device. Netgear has been creating software and manufacturing network hardware since 1996, although some of its manufacturing has been outsourced in recent years. Some Netgear products are prone to vulnerability since they rarely release routine security updates for their consumer products.

NETGEAR Wireless Configuration Utility
Netgear's WLAN device configuration program. Don't need if using XP's built-in WiFi mgmt
Installed when you install a NetGear Wireless LAN card
It reboots my computer if not stopped
  Eric Wu  
bit of software associated with netgear network management software

Netgear's wireless NIC Smart Configuration application that runs itself at startup. On my systems, one win98 and one winxp, the application uses way too much cpu resource. It calls net.exe over and over, and is poorly behaved program. You can get rid of it if you use XP, and you can EXIT the app after you have booted otherwise. Your system will speed up with it gone.

Netgear's Wi-fi configuration utility. Has many features, recommend using it and disabling XP's native Wi-fi utility.
When we installed the software for the NETGEAR PCI card WPN311, the file wlancfg5.exe was installed in the NETGEAR folder. This was done on a new computer fresh from an unopened box. At the time, the only other installed software was NORTON antivirus. After the NETGEAR software was installed, the computer would 1.lock up or 2.bluescreen in an hour or less. If powered up from a cold start, and no one logged in, the computer would bluescreen in about an hour.

When my wireless connection freezes (both the Netgear Utility and the XP wireless are frozen), I attempt to reboot my computer and a message appears stating that wlancfg5.exe is not responding. I have to do a hard shutdown. It definitely is a Netgear utility, but I'm thinking it's not behaving correctly, thusly creating a problem with maintaining a wireless connection.
Sends too many packets. Is not essential
after restart my system it automatically solved.
The constant page faults fill up memory and waste resources. I play an online MMORPG which runs substantially better after I've deleted it.

My Laptop depends on this application to connect to the internet. I often get the response Wlancfg5 not responding IF I suddenly have no internet connection.

Using alot of resources, and doesnt seem to affect my net preformance when i end the process.

Best practices for resolving wlancfg5 issues

A clean and tidy computer is the key requirement for avoiding problems with wlancfg5. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the wlancfg5.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
