Hello,<o:p></o:p></p>

<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
I found an issue in the following scenario:<span lang="HE" dir="RTL"><o:p></o:p></span></p>
<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
I have one hidden profile (scan_ssid=1) defined in my conf file.<o:p></o:p></p>
<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
The supplicant performs Normal Scan before performing Sched Scan.<o:p></o:p></p>
<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
In the Normal Scan, it first scans for wildcard SSID, waits for 5 seconds, and then scans the profile's SSID.<o:p></o:p></p>
<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
So the connection to the profile takes ~10 seconds. This is a bad user experience.<o:p></o:p></p>
<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
<o:p> </o:p></p>
<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
Suggested solution:<span lang="HE" dir="RTL"><o:p></o:p></span></p>
<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
In the Normal Scan, switch the order of the scans. Start with the profile's SSID and after 5 seconds scan for wildcard SSID.<o:p></o:p></p>
<p class="MsoPlainText" style="text-align:left;direction:ltr;unicode-bidi:embed">
This can be achieved by the following patch:<o:p></o:p></p>
