<div>Hi Luigi,<br>
<br>
</div>
USB wifi adapter compatibility is tricky for instances where
you want the radio to broadcast multiple SSIDs (i.e. adhoc
signal and a local AP signal). To date, I've only been able
to get this working on TL-WN821N <b>v3</b> which uses the <b>ath9k_htc</b>
driver, not v2 which uses the carl9170 driver. Likewise for
the TL-WN722N. Even then, I had patch the ath9k_htc driver
(patch for OpenWRT included) to make the radio do multiple
SSIDs.<br>
<br>
</div>
On the other hand, if you are using the commotion-mesh-applet
tool under a compatible desktop GUI like GNOME or Mate, it
will only start a single adhoc interface, rather than multiple
SSIDs. The caveat, at when I last tested that tool in March,
was that it expected the USB wifi interface to be named
"wlan0" rather something else like "wlan1."<br>
<br>
</div>
Could you respond with the OS and kernel versions on all
machines involved, i.e. your laptop and the rPI? The USB wifi
driver might also be a bit stale, too.<br>

totally agree that main challenge is to pick up a good USB
wireless.<br>
I have bought (1 month ago) theTP-Link TL_WN821N(V.2).The
V.2(I found out later) is not in the Linux kernel. I had to
install the firmware carl9170. Easy to make it works in
managed mode.<br>
Still not working in ad-hoc mode.Not sure if it is a problem
of the firmware( it should work also in ad-hoc) or the
/etc/network/interfaces and wpa_supplicant setting.<br>
Assuming that TL_WN821N(v.2) works,could be helpful to have
some info from you based on your experience.<br>
After I'll buy the TP-Link TL-WN722N<br>
Thanks.<br>

Hi Luigi,<br>
<br>
Glad to hear about all the successes!<br>
<br>
I have made a mesh network from Raspberry Pis before
(battery-powered,<br>
even), so it's definitely possible. The main
challenge is to pick a good<br>
USB wireless adapter. I recommend the TP-Link
TL-WN722N [1], since its<br>
driver supports ad-hoc mode in recent Linux kernels.<br>
<br>
Then, you install your Raspberry Pi operating system
(I recommend<br>
Raspbian), and configure the wireless adapter to be
in ad-hoc mode with<br>
the correct SSID,BSSID,channel, etc. This is done in<br>
/etc/network/interfaces...if you need info on how to
to that, I can give<br>
you resources.<br>
<br>
Then you can install and configure OLSRd on the Pi,
so that it can mesh<br>
with the other devices. For an olsrd config file,
you can look at<br>
/var/etc/olsrd.conf on one of your picostations for
an example.<br>
<br>
Let us know how that goes!<br>
<br>

It was a pleasure to join Commotion team several
months ago.<br>
With your support I was able to implement a local
mesh newtwork with<br>
two routers (picostation), my two Linux LapTops
and Iphone.<br>
I have also tested the capabiity of commotiont
application portal by<br>
installing either Tidepools and MediGrid.<br>
Most of the time spent to play with the raspberry
and after installing<br>
MediaGrid.<br>
Everything works.I tried to upload and share some
music and the chat.<br>
<br>
Based on this experience I have some questions.<br>
a)How to make the Raspberry pi part of the Mesh?In
my application I have<br>
connected it to the AP as external device.<br>
b)Is there any future for the integration of
raspberry in the commotion<br>
network?<br>
<br>
Last question.<br>
c)My idea is to buy two Nanostations and to extend
the range of my local<br>
mesh.<br>
Any suggestion based on your experience?<br>
To reach longer distances(1 to 2 miles)I would
choose a 5Ghz (the power<br>
limit in Italy is 1 W output power at 5Ghz).Much
more less for Wifi(15dbm).<br>
Thanks for your support and suggestions.<br>

Everything at home which has a wifi interface
can be connected and the<br>
network(built by 2 picostations) is working as
ad-hoc network.<br>
If the fridge,the oven or the stove had a
wifi interface, they would<br>
be connected to <a moz-do-not-send="true"
href="http://commotionwireless.net"
target="_blank">commotionwireless.net</a> too.<br>
The only issue I have found is that if I
try to access internet with<br>
the linux laptop using the ad-hoc interface of
the AP router,I can't.<br>
But if I use the router AP as master ,I
can.<br>
I red somewhere that this feature is not
avalable for laptop. Please<br>
confirm.<br>
On the other end if I connect a local web
server to the POE LAN port<br>
of one router, I can have access to the web
page also from the linux<br>
laptop through the ad-hoc interface of the
router(picostation).<br>
As a demo to show the capabilities of
commotion solution I would<br>
like to implement a Server application.<br>
Which application do you suggest first
that can explain better the<br>
commotion solution capabilities?<br>
I need to recruit some people on ths
project.<br>

When connecting your laptop to the picostation
over ad-hoc, do you have<br>
olsrd running on the laptop? If so, and if the
picostation has access to<br>
the internet, your laptop should get a route via
olsrd to the internet<br>
as well.<br>
<br>
To troubleshoot this, try checking the output of
"nc localhost 2006" (to<br>
show olsrd info), and "route -n" on the laptop
to show local routes.<br>
<br>
As for applications, I would suggest either
Tidepools (a local mapping<br>
application: <a moz-do-not-send="true"
href="http://www.tidepools.co/"
target="_blank">http://www.tidepools.co/</a>)
or MediaGrid (a secure<br>
file-sharing and webchat application:<br>
<a moz-do-not-send="true"
href="https://github.com/danstaples/MediaGrid"
target="_blank">https://github.com/danstaples/MediaGrid</a>).
They both require a good bit<br>
of tinkering to work well, but could be a fun
project. Or you could try<br>
for something simpler to setup, like an Apache
web server.<br>
<br>
Also, when you have the server set up, try using
the application portal<br>
on the picostation<br>
(<a moz-do-not-send="true"
href="https://code.commotionwireless.net/projects/commotion/wiki/Application_Portal"
target="_blank">https://code.commotionwireless.net/projects/commotion/wiki/Application_Portal</a>).<br>
<br>
When you "add an application", it will show up
automatically on other<br>
routers nearby within a few minutes!<br>

As for your other questions, we would like to have a
Commotion image for<br>
Raspberry Pi, but it is not a top priority for now.
Perhaps someone from<br>
the dev community can create one ;)<br>
<br>
And we often use Nanostations for connecting parts of
a mesh network<br>
over longer distances. They work really well for that
purpose, but<br>
aren't the best for providing access points since they
are directional.<br>
