I recently bought a new WIFI adapter for my desktop but it would not work.
It needed the WLAN services to be running in order to use the built in Windows wifi manager.

I found out they were disabled and trying to enable them on an administrator account would only give me an error "error 1747 the authentication service is unknown". This error includes the event logging service and 3 other services.

Looking through google and various forums "netsh winsock reset" on a command console being ran as administrator was suppose to fix it but this does nothing to solve the problem.

I also looked through regedit to give LOCALMACHINE all the privileges but still nothing.

I reinstalled Windows 7 Professional on the current partition (I didnt reformat just reinstalled Windows) and since I have no internet to authenticate it, now it says it is not a genuine copy >_>

The wifi adapter is the Linksys AE1000 running on a Windows 7 Professional x64 operating system.

I have no idea what else to do other than doing a clean reformat (but as far as I can remember those services never worked even on a clean format and I never needed it because i was connected directly.)

Thanks!

The CD that came with it would not continue unless it found the services to be running. (Cisco Connect I believe)

I also tried using 3rd party wifi managers like netstumbler but the programs could not detect the adapter.

Have you tried going to services in administrative tools in control panel and see what the settings are for those services?

Try this: How to determine and to recover from Winsock2 corruption in Windows Server 2003, in Windows XP, and in Windows Vista

Found this after googling Error 1747.

I keep getting this error every time I go to Services and try starting WLAN..I just upgraded from XP to Vista to 7 and now I have NO wireless connection, only wired works..

My network adapter is a Broadcom 802.11 Multiband, is up-to-date and working properly (so it says)..I have an HP Pavilion dv5139us laptop, a Linksys WRT54G router and a Motorola modem (can't remember the model at the moment)..any suggestions? If you need any screenshots to help solve this "mystery" let me know which ones.

Thanks! :thumbup2:
