Multiple Wifi?

[elbombillo]

I have a RPi with WiFi adapter, I have two locations with 2 access points. I want to be able to go between two locations and have my RPi connect to either one.

You have have multiple access points in your wpa-supplicant.conf and it will connect to what is available and to the higher priority one multiple are available.

You just just be able to add the access points via wpa_gui and be good to go. I manually configured mine via /etc/network/interfaces and /etc/wpa-supplicant/wpa-supplicant.cond

As a full example....

I don't bother with the GUI at all...

In /etc/network/interfaces

Code: Select all

...
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

In /etc/wpa_supplicant/wpa_supplicate.conf

Code: Select all

update_config=1
network={
        ssid="brutus"
        psk="PASSWD"
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP
        auth_alg=OPEN
        priority=5
}

network={
        ssid="TNETRezound"
        psk="PASSWD"
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP
        auth_alg=OPEN
        priority=9
}

network={
        ssid="AnotherSSID"
        psk="PASSWD"
        proto=RSN
        key_mgmt=WPA-PSK
        pairwise=CCMP
        auth_alg=OPEN
        priority=5
}

The Priority allows me to select by priority if I have more than one SSID in the same location. As an example, If my HTC Rezound (TNETRezound) is up as a hotspot, it will take priority over any other SSID and it will use it. This is very useful if I am at a location where I don't yet know or have access to the local WiFi system. I can find out what is and then use my phone to make the changes necessary, turn off the phone's hotspot and connect to the local WiFi.

Code: Select all

...
iface wlan0 inet manual
...
iface default inet dhcp

why did you put those 2 lines?
I used iface wlan0 inet dhcp
cos such example didn't work for me...
