RtWLan.exe is the Realtek Wireless LAN utility. It is needed to drive wireless LAN cards based on the Realtek chipsets.
It is an application used to configure wireless lan cards.

Asus Realtec Wifi control app.
REALTEK Wireless LAN Uitity
Memory usage too high after 4-5 hours work. In my case about 200MB. I got "swap file too small" warning. I kill the process .
Real Tech Wireless Lan driver - typically the one bundled with onboard adapters on certain MOBOs ... mine is an ASUS .. important to have the adapter working, but can be deleted if not using it.
it's for the netgear wireless usb receiver. not harmful AT ALL

Loaded with brother printer WIFI app
Yes, it is for your wireless...remove it and you'll break your network connectivity
Bad behaving, but not a virus (scanned with Avast). Like the other poster, after a certain amount of time (within 24 hrs), resources used up, causing highlighted desktop icons, disappearing taskbar icons, disappearing start menu and memory errors when trying to execute programs, even task manager.
You can install the driver without this annoying utility.
Wasn't detected and removed until after a windows update. It came from a folder for my EnGenius usb wlan adapter. Network still works without it.
Appeared when I installed an ALFA Wi-Fi USB adapter, which utilizes the Realtek wireless utility. I see two appearances of it running under Task Manager, each using about 6k - 6.5k of memory. I should terminate one instance to see what happens, but have no problems.

I have tried ending the process in Task Manager, it says Process cannot be ended. I also right clicked on the process while I was in Task Manager, I tried going into the properties so that I could change or edit the security setting, meaning the permission and owner. I couldn't find this file anywhere on my PC, as well as these following processes: 1.nvxdsync.exe 2.nvvsvc.exe 3.csrss.exe 4.winlogon.exe and then of course 5.RtWlan.exe None of these files can be found anywhere in the system as I have searched every single corner of the memory for it, manually I might add. These processes have the same effect ast the RtWlan.exe ... Cannot enter the properties in Task Manager and cannot kill it either. There are also some other files which pop up every time I start up my notebook : Here they are. ggddllhost conhost and then HKCmd I was able to end the processes and edit the security settings such as permission and ownership, but they still keep starting up automatically, I have attempted to delete these processes by taking ownership and then Ctrl+Shift+Deleting, but the system won't allow me to delete it.... Do you think that this might be some extra files that Microsoft decided to add on the Windows 7 cd's? or has Microsoft been compromised by the USA as always?
Mine came with software for MODECOM wifi adapter. Network still works after killing.

Best practices for resolving RtWLan issues

A clean and tidy computer is the key requirement for avoiding problems with RtWLan. 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 doing a repair of your installation, or in the case of Windows 8, 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 RtWLan.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.
