Pavilion laptop set up to connect to home network automatically; D-Link N-band USB; D-Link N-band Router. Home network: laptop; desktop; & HP home server. I've been using this set-up for years, but suddenly can't get auto connect to work. Network icon in tray shows that networks are available; list includes my home network, with a fair signal; can select my home network and click on 'connect'; network connection occurs. (My desktop also uses a D-Link N-band USB adapter; also set up with auto connect; and it always connects upon start-up.) If I go to 'Manage Networks' on my laptop, my home network is listed, with 'Connect automatically'; but auto connect never occurs. All this is only a minor irritation, but I'd like to know why auto connect won't work. Thanks for any enlightenment.
