connect to a Free Wi-Fi Hotspot

[ccc]

Hi

I've notebook EEE PC 1000H from Asus with freeBSD 7.2 and ndis module.
There is WPA2-PSK configured.

Howto configure wireless interface to switch from WPA2-PSK to a free open Wi-Fi Hotspot
and back if needed?

Yesterday afternoon I gave you this link:

http://www.freebsd.org/doc/en/books/handbook/network-wireless.html

You can/should use wpa_supplicant for both encrypted and unencrypted wireless networks. Just read that section of the handbook and the wpa_supplicant.conf man page.

Yep and THX.
My problem is, I have configured WPA2-PSK for my home wireless router, but if I'm traveling my notebook should switch to the open, unencrypted Wi-Fi Hotspots.
Should I write an extra script to change the network settings or there is an other solution?

Re-read the wpa_supplicant.conf man page :-) You can configure different wireless networks in there with different priorities:


network={
ssid="myssid"
key_mgmt=WPA-PSK
pairwise=TKIP
psk=key
priority=5
}

network={
key_mgmt=NONE
priority=0
}


It will connect to any available open wireless network, but only if "myssid" is not available.

If you are using DHCP in both locations, it will just work fine. If you switch from one location to another, without shutting down, you can force wpa_supplicant to rescan, and dhcp to restart, by running '/etc/rc.d/netif restart wlan0' (assuming wlan0 is your interface), but I believe this will happen as soon as wpa_supplicant detects the network change anyway.

Thx, I've tried the following configuration in /etc/wpa_supplicant.conf on my freeBSD 7.3 RELEASE:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
eapol_version=2
ap_scan=1
fast_reauth=1


network={
scan_ssid=1
ssid="myessid"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk=secretkey
priority=5
}

network={
key_mgmt=NONE
priority=0
}
If I understand correctly, the highest priority number has the highest priority.
Now if I try to restart network:/etc/rc.d/netif restartthen I'm getting the IP address from my neighbour with unsecured instead of my secured wlan.
Howto set my secured wlan as a default connection?

not sure how to fix it but something i did was use wifimgr. it created a wpa_supplicant.conf for me and i used that as an example.
