Point to Point Bridge with two RB411, is it possible?

Hi, I bought same days ago two antennas (24dBi) with RB411 L3 integrated, precisely this one: http://www.anteny.net/bridgeclient-station-strongbridge-5ghz-24dbi-p-647.html.

My scenario is:

Point A <----------------------- +/- 10 Km LOS --------------------------> Point B
(ADSL Connection) (Client with no ADSL Connection)

At first I followed a video tutorial and I setted the antennas one as AP Bridge (A) with WDS and the other like station wds (B) and the link worked good with SNR=6/7. Then I lost the configuration…

I would like to know if is better to use Nstreme protocol or not? In other words..Which is the best configuration for my scenario?
Is it possible with 2 RB411 L3 or I need the L4?
It exist some configuration tutorial which can help me?
What about PPPOE?
Of course I would like to use a WPA secure configuration.

I hope to read of someone of you asap!!

Cheers

Giuseppe

If you have RB411s, you CAN’T use ap bridge.

You can use bridge mode and wds to make the link.

if you use wds yes u can

Can you help me with some type configuration or tutorial?
