Unstable with other antenna

[qeqe]

Hi! This will be my first post here!

When i try to use two other antenna (9dBi Rubberduck) then the originals i got a unstable connection and the pineapple can't find other then a few accesspoints round.

I got the same error when i use them on my other router but when i change to 100mW in dd-wrt on the router all works perfect. I try to find this settings on my Pineapple Mark V but i can't find that settings and have try to change txpower with no luck.

The spec. on the antenna is

Frequency Range: 2400 - 2500 MHz
Amplification: 9 dBi
Max power: 100 w
Connection: RP-SMA

And if u want to check more about the antenna you can go to https://translate.google.se/translate?sl=sv&tl=en&js=y&prev=_t&hl=sv&ie=UTF-8&u=http%3A%2F%2Fwww.davido.se%2Fshop%2Fproduct_info.php%3FcPath%3D26_34%26products_id%3D121&edit-text=&act=url (is a google translation from swedish to english)

What can i do to fix this?

The connector on the pineapple is SMA not RP-SMA.

The hakshop sells the adapter.

The TX power is locked for now on wlan0.

Ah to bad... it looks so similar. I will buy a adapter.

The TX power is locked for now on wlan0.

Thats why i can't change wlan0...

Have i right when the wlan0 is AR9331 and wlan1 is RT8187?

Yes the ar9331 is wlan0.
