One chain on one card looks like is broken. Try other channels and signal must be over -40 not -27. ALso must be almost the same not 20dbm difference. Also for 2 km and 10mbps, SXT lite 5 is more than enough.

i think signal strength -27dbm is better than -40dBm

Stronger signal is not always better.

Imagine someone standing right next to you shouting in your ear. You might be able to make it out but it would be better if they lowered their voice. Same thing with radio.

There is a sweet spot for radio signals. Too weak or too strong is not good.

The signal is to match on -41 dB the signal can disturb itselfs.
-60 dB is good and normal.

OK thanks

Yes, i have got an SXT-Lite5 1 km link, the signal strenght is around -60dBm, but i can not use 802.11 N in this town, because the local WISP using every channel, but for 2-3 km the sxt should be good, if the freshnel zone is perfectly clean
