Description: ------------ output from iwconfig on Ubuntu 6.06.1 lists the rssi value as "Signal level:-77 dBm". Using a colon rather than an equals sign so a tweak to the preg_match expression is required. output of iwconfig --version is as follows: kguest:~$ iwconfig --version iwconfig Wireless-Tools version 28 Compatible with Wireless Extension v11 to v19. Kernel Currently compiled with Wireless Extension v19. wlan0 Recommend Wireless Extension v16 or later, Currently compiled with Wireless Extension v19. Test script: --------------- <?php require_once("Net/Wifi.php"); $nw = new Net_Wifi(); $interfaces = $nw->getSupportedInterfaces(); foreach($interfaces as $interface){ $nwc = $nw->getCurrentConfig($interface);//new Net_Wifi_Config(); if ($nw->isConnected ($interface)){ echo $interface, ": connected\n"; } else { echo $interface, ": not connected\n"; } var_dump($nwc); } ?> Expected result: ---------------- kguest:~$ php nw.php wlan0: connected object(Net_Wifi_Config)#2 (10) { ["activated"]=> bool(true) ["associated"]=> bool(true) ["ap"]=> string(17) "00:12:17:DF:2C:AE" ["ssid"]=> string(17) "Project-Node-Zero" ["mode"]=> string(7) "managed" ["nick"]=> NULL ["rate"]=> string(2) "11" ["power"]=> NULL ["protocol"]=> NULL ["rssi"]=> string(3) "-66" } Actual result: -------------- kguest:~$ php nw.php wlan0: connected object(Net_Wifi_Config)#2 (10) { ["activated"]=> bool(true) ["associated"]=> bool(true) ["ap"]=> string(17) "00:12:17:AD:2C:CE" ["ssid"]=> string(17) "Project-Node-Zero" ["mode"]=> string(7) "managed" ["nick"]=> NULL ["rate"]=> string(2) "11" ["power"]=> NULL ["protocol"]=> NULL ["rssi"]=> NULL }

Ken, could you please attach the raw iwconfig output to the bug? I need it to make a unit test.

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on pear.php.net by the end of next Sunday (CET). If this was a problem with the pear.php.net website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
