Your signal is not very good on 3 km. For a point to point on 3km should be around -65 or less, depending on our aerial. Most probably interference. Signal strength is usually better at night, dew to less noise, like the sun. We have a link though, where at night spot lights is switch on that is near the dish and this just kill the throughput, though nothing is noticed on the signal strength. Still contemplating how to fix this.
Happy days. :-)

Make sure the SXT devices are correctly mounted (mind the polarization), also make sure to enable both chains in the "HT" tab of the wireless settings. See this document for mounting tips: http://routerboard.com/pricelist/downlo ... ile_id=280
