network priority and autoreconnect (OS2008)

I am wondering if this is even possible, but is there a way to set up
priorities (as in wpa_supplicant.conf, for example) for the different
networking connections (including tethered BT)? I am getting really sick
of having to manually reconnect each connection.
My personal setup:
Home network: visible SSID, WPA-PSK, reconnects automatically
Work network: hidden SSID, WPA-PEAP/MS-CHAPv2, does not reconnect
automatically
Phone network: HSDPA via BT (AT&T), does not connect automatically

The biggest problem for me is that if I am connected to my phone (say, on
my commute...) it keeps the phone connection even if the Home wireless
network is available. Same is true of the work network, although the work
network never autoconnects. The real problem here is it drains my phone
battery unnecessarily when a WLAN is available.

I have no problem editing configuration files by hand, but is this even
possible? It is really a source of irritation for me.

I also would rather not _ever_ be prompted to set up a new network - I will
browse for one when I want to add something to my preferred network list.

Any help greatly appreciated.

Rgds,
Josh

I posted about this exact same issue as it's how the iPhone works and
one of the very cool features of that device.

http://www.maemoapps.com/2007/10/23/maemo-feature-request-connection-switching/

In the comments is a link to the roadmap wishlist -
http://maemo.org/community/wiki/roadmapwishlist/ where I also added it
formally but have not heard anything since then.

Our current software implementation does not support this, not even
with some tweaking. Sorry.

I believe I have seen wpa_supplicant for the N800 somewhere (probably
OS2007 at that time). Wouldn't that work, with the regular network
selection set to a dummy AP?

Hi Kalle,
Thanks for the reply. Do you know if it is possible to use
wpa_supplicant (I realize I might have to port it myself), just
wondering about driver compatibility. Otherwise, maybe something like
gnome network manager to wrap it to get support for the BT DUN.

I saw the blog post and the feature request on maemo - any idea of
whether this is in scope for a future release?

Regards,
Josh

I think it would handle everything besides the BT DUN - I replied to
Kalle before I got your message, thanks for the suggestion - along the
same lines as my thinking :)

I really need to get my build environment up...

Current WLAN driver is incompatible with wpa_supplicant, but Lauro
Venancio has posted a patch to cx3110x-devel for supporting
wpa_supplicant:

I don't see any easy way to do this (ie. automatically switch from
BT-DUN to WLAN). Basically you would have to replace icd with some
other component handling higher level connection switching.

The iPhone seems to continue to scan for networks on occasion even
when connected over edge (not DUN) which lets it see and auto-switch
to your known wifi locations. This is pretty slick actually and when
you walk in your house the device is on the faster network...

Yummy.

Although I would prefer it not do that and kill my existing ssh
connections by changing my externally visible IP address.

Agree - the negative is that it auto-switches when you walk into
starbucks to t-mobile and unless you are prepared to login (or have an
account) you lose the link or process on which you were following ...
There's got to be a way though to consider how the E-Series phones let
you create a stack of connection priorities ...

When I started running around with my 770, I found that the 'screen' program was my best long-lost friend. Had been a while since I used it, but I fell back in love with it now that I basically carry a wireless dumb terminal/mp3 player in my pocket.

Changes unexpected disconnects into a very minor annoyance.
