Working on a friends XP PC (Pro SP-3 OS) he has a SMC USB WLAN 'dongle' or wireless lan that he has used to connect. I had to reinstall his OS and now has stopped working even with installing the drivers from their site. I've gone into 'services' made sure it was started. I've rebooted restarted tried all the usb ports and all I get is the windows default 'error' sound. In Device Manager it shows as 'Other Device' with the yellow question mark. I've uninstalled it restarted ad nauseum with no luck. I can take it and plug into any other pc and it works like a charm so that eliminates the unit itself and to top it off it works without installing any drivers. I'm thinking thats because windows auto downloads it normally. I am totally perplexed as to why it refuses to work on the new OS install. All six USB ports work as I've verified them with other devices.
The model is a SMCUSBS-N4. It's listed under devices as a 802.11 n WLAN. I've tried everything I can think of.
If anybody can point to something I may have missed and I hope I've explained all the things I've covered so far
