Re: nm_device_wifi_get_access_point returns an invalid number of APs.

[pan son <sonicpan sonicpan gmail com>]

I am running 0.8 Network Manager on my ubuntu 10.04.

I see that the Network Manager applet generally refreshes its list (or calls nm_device_wifi_get_access_points) at most once an hour. (?applet-device-wifi.c:1017)

Thanks,
Vink

What specific version of NetworkManager are you using?
