New page

To enable:

<pre><nowiki>
iwconfig eth0 mode ad-hoc essid pre
</nowiki></pre>

This of course disconnects your existing wi-fi connection, so make sure you're connected via EVDO or USB.

This is just the standard linux method for enabling ad-hoc functionality. However, if you've got WiFi turned on via the Pre interface, it's not going to work for long, since the WiFi manager forces the device back into Managed mode periodically. In order to avoid this, you need to turn off the WiFi functionality through the webOS GUI. Then, bring the WiFi card up using:

<pre><nowiki>
/usr/sbin/wifidriver -i
</nowiki></pre>

This will load the driver for the WiFi card, but will not send any notifications to webOS, so it won't try to force the setting back to those it likes. At this point, the standard command above will work, and you can create an ad-hoc network. Useful for ssh-ing into your Pre when there are no access points available.

GUI enabled application to switch the mode coming soon..

Testing notes:
Enabling wi-fi like this seems to turn it on full blast. The Pre battery will heat up quite a bit and if you're close to the device you may not get a decent signal due to overpowering principles of antenna theory.. Consider adding settings to limit wifi power output to 10-20% to help preserve battery life and minimize heat output. The nature of ad-hoc will guarantee some level of proximity, and therefore not need maximum power output. ~ Robi
