Bug Description
Binary package hint: network-manager
Network manager is substantially slower than many other solutions in terms of finding and connecting to wireless networks.
Wifi-radar or "iwlist scanning" for example, often show wireless networks 15-30 seconds before nm-applet lists them.
Likewise, attempting to connect to one of these networks with nm-applet often takes well over 30 seconds. While using wifi-radar, or manual connection with "iwlist scanning; iwconfig <interface> essid <network name>; dhclient <interface>, takes only moments to get from start to dhcp discovery (and seconds after that), nm-applet often hangs for 10-20 seconds on "Preparing" the interface for a wireless connection before even starting dhcp discovery.

To post a comment you must log in.
your bug covers two issues:
1. find: network manager updates its wifi network list in a timed fashion ... thus the latency in network discovery. This is tracked definitly tracked in another bug (sorry no time atm to look the bug up)
2. connect: network manager takes too long to recognize that you did associate.
So i would suggest to look into 2 for now ...
in order to get an idea, i need your wifi chipset and your syslog/daemon.log.
