I tried to connect manually with wpa_supplicant without "ap_scan=2", but it would not connect in five or six attempts. As soon as I added "ap_scan=2" back, it connected first time. The only way to get my wifi hardware to work is by using the Broadcom wl driver: $ dmesg | grep Hybrid eth1: Broadcom BCM4359 802.11 Hybrid Wireless Controller 5.100.82.112 $ lsmod ... 02:00.0 Network controller: Broadcom Corporation BCM43228 802.11a/b/g/n http://www.broadcom.com/support/802.11/linux_sta.php hybrid-portsrc_x86_64-v5_100_82_112.tar.gz $ uname -a Linux boxdell 3.8.13-tinycore64 #777 SMP Fri Oct 18 15:13:45 UTC 2013 x86_64 GNU/Linux ..so it is definitely not 8 years old. Trying to connect to a Cisco WAP4410N As tinycorelinux is analogous to a live CD distribution (the file system is copied to RAM on boot), nothing is saved between boots, so the networkmanager wifi connection is re-created each time when I try to use network-manager-applet to connect to a hidden network. $ nmcli con list id bobnet | grep hidden 802-11-wireless.hidden: no ..but I cannot find a way to change this to "yes" - "nm-connection-editor" does not show the "hidden" parameter and if I edit system-connections/bobnet to read as follows: [802-11-wireless] ssid=bobnet mac-address=64:27:37:22:AB:51 security=802-11-wireless-security hidden=yes .."hidden=yes" seems to be ignored, so how do I change it?
