Driver download driver 3COM 3CRUSB10075 wireless LAN USB for windows 7.

SOURCE: 3COM Office Connect 3CRUSB10075

are you using windows xp? vista? 98?

I'll guess at xp.(and that you're using the windows software to connect)

Double click the wireless connection icon in the bottom right (the one that flickered when you're online.

Click 'view wireless connections'

click 'change the order of preferred networks'

Now select everything on the list and delete it apart from your own.

Now click 'advanced'

make sure 'automatically connect to non-prefurred networks' is NOT ticked.

Click close, then ok.

You should be ok now.

Regards

Tony

I did not solve the problem. I chose an easier way. I just replaced the 3Com Wireless Adapter with a NetGear USB adapter for which I have security instructions.

Kind regards,
