All good so far. NM periodically scans to check if the configured AP is in range, and if so, asks for the key to connect (if in a disconnected state). > The problem with this behaviour is that if there is a power failure, the > computer doesn't reconnect to the network like it should.

Very bad. :) > How do I ensure that it reconnects to this network only when it comes > back without any human intervention on each event? I am not sure if NM has an option to store keys. But you can use wpa_supplicant and store the key in your config file. Once wpa_supplicant is started in the background, and if the AP drops out for some reason, wpa_s periodically issues a scan request to the driver and automatically reconnects if the AP comes back online again. No 'human intervention' is required. :) Sujith -- http://sujith-m.blogspot.com _______________________________________________ To unsubscribe, email [email protected] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
