Hi,<br><br>I tried to add the field frequency like you advise me, but when I started wpa_supplicant with the command wpa_supplicant -B -D madwifi -i ath0 -c /etc/wpa_supplicant.conf, I got this error:<br>Failed to read or parse configuration '/etc/wpa_supplicant.conf'.<br>(the version of wpa_supplicant is 0.5.6)<br><br>Anyway, without the field frequency in the configuration file, I started iwconfig and the frequency was the same for every computer, such as key and cell.<br><br>Any other idea?<br><br>Thank a lot<br><br><b><i>Dan Williams <dcbw@redhat.com></i></b> ha scritto:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> On Tue, 2006-12-19 at 17:14 +0100, Stefano Paris wrote:<br>> Hi,<br>> <br>> I tried to connect 3 pc in ad hoc mode with the followed configuration<br>> file:<br>> <br>> ctrl_interface=/var/run/wpa_supplicant<br>> ctrl_interface_group=0<br>> ap_scan=2<br>>

Without the 'frequency' setting<br>in your network config (added to 0.5.4 and later I think), the card may<br>not know which frequency to tune to. You must have _all_ members of the<br>adhoc network on the _same_ frequency.<br><br>So, on each computer after
configuring it with wpa_supplicant, run an<br>'iwconfig' and look for the frequency/channel #. If they are all the<br>same, then we can rule out this issue.<br><br>I know that with ipw2200, you need to tell the card which channel to<br>join explicitly.<br><br>Dan<br><br></blockquote><br><p> __________________________________________________<br>Do You Yahoo!?<br>Poco spazio e tanto spam?
