Model : CPE210

Hardware Version : Not Clear

Firmware Version :

ISP : Vodafone Portugal (Fiber)

I'am trying to get internet from a friend over 1.3km, straight line of site, without trees or buildings, i can see clearly his apartment.
I already had a TL-WA5210G(as client), and my friend have a router TL-MR3420, I runned a test and I got 10m for download. I though WOW, if i can get this sped only with one outdoor antena, let buy another one! --'
Thats when all the problems started, I bought one CPE210 and used it as AP, and after 1 or 2 hours trying to allign, I cant pass over 1mega of speed = total fustration.
Then I tryed the other option possible, TL-WA5210G as AP and CPE210 as client, the problem remains....same speed, only one bar for wirelles signal...

1,3km its too much distance for antenas such as these?
What is getting me confused is that i can get more speed with the router....
Any help?
