<br><div>Hello there,</div><div><br></div><div>I'd like to share a couple of things I've learned today trying to setup my alix as a wireless access point with WPA2. Surely these are obvious tips for the most advanced users, but maybe I'm not the only one who doesn't find these things obvious.</div>
<div><br></div><div>My thanks to other contributors in the list. Reading many posts helped me getting to this result.</div><div><br></div><div>1st tip: when you try to create a bridge, remember that the physical interface should NOT have an IP address. The IP address should be assigned to the bridge interface.</div>
<div>2nd tip: WPA-PSK passwords should be at least 8 chars long. So if you set up something temporary just for the tests be careful, since it's very hard to get a meaningful error message from hostapd.</div><div><br>
</div>
<div>And now the long version. ;-)</div><div><font class="Apple-style-span" color="#500050"><span class="Apple-style-span" style="border-collapse: collapse;"><font class="Apple-style-span" color="#000000"><span class="Apple-style-span" style="border-collapse: separate;"><br>

<div><br></div><div>steps:</div><div><br></div><div>assign a STATIC IP address (A.B.C.D) to the alix (since the IP address will be assigned to the bridged interface br0, not the phyisical interface, so dhcp might cause problems)</div>
