Belongs to Intel Pro/Wireless Network Connection Software
Intel PRO Wireless 2200BG user here. Full system scan with Malewarebytes detected nothing. I disabled this file in TaskMgr, then went into the directory where it usually is found- C:\Program Files\Itel\Wireless\Bin,, and renamed it by putting an underscore character preceding the actual file name. I had recently re-installed the 2200BG network adapter software because I thought I may have accidentally corrupted it during a hd defragging session - After disabling in TaskMgr & renaming as prev specified my browser page-open speeds, which had been lagging HORRIBLY slow, immediately,, on-first-try,, picked up so much so fast even I was a little surprised at the result. Since wifi networks are already slower than regular broadband or satellite connections I really don't see why this non-essential thing is even included,,the only it contributes is confusion.. Disabling it didn't affect my functionality at all, only improved it. In fact, I also disabled my (wifi) internet connection after disabling & renaming dot1xcfg.exe just to see if doing that would result in that I could no longer get online at all -- THE POLAR OPPOSITE. I got on, opened a fresh new browser tab, clicked a bookmarked link, it opened lightning quick, I clicked a link within the page, and the tab refreshed into the new page, also very comfortably fast. Finding the info on this page was a godsend to me to more than just narrow down and whittle away at the process-of-elimination, which is real tedious and time consuming. Good luck to you. The info in this thread & post may just be what your looking for also. Good luck.

Best practices for resolving Dot1XCfg issues

A clean and tidy computer is the key requirement for avoiding problems with Dot1XCfg. 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 Dot1XCfg.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.
