Hello, Extrange problem, every 10 min the other porint disconnect and reconnect. Iam use in both point RB112 and sr2 and power supply 48v 0.5a

The “extensive data loss” is just that. Data loss. Without more information I can only give you a few directions.

  1. Make sure your channel bandwidth is not outside the transmit rate.
  2. Look for noise entering your channel with.

For example 00:15:6D:53 is a Umb card. I assume this is 2.4? if so you are using 2.4 you are sending the data at a 20mhz channel with. If you are using a 5.5 transmit rate (or the card is neg at that rate) the packet is being split (like a mirrored hard drive) on each side of the center channel. As long as one side makes it through you are good to go and no one even notices. Your SNR and TX/RX will look clean even your TCQ will be at a reasonable rate. However the 20mhz channel is being irrigated by noise and you don’t even see it due to the reliability of the transmit rate. Now all of a sudden the noise climbs into the second 5.5 (the upper or lower end of the 20 mhz channel) now both of the replicated packets are effected and the data loss increases to the point where the MT looses connectivity. I have seen this when DSSS (Direct Sequence) is trying to co exist with FH (Frequency Hopping) in there respective band. The respective transmit rate I sited above also holds for the 5ghz and other frequency’s as well. The replication of data above and below the center channel occurs on most of the ISM/UNI bands and standards. The other thing is setting the card at one of the “edge” frequency’s supported without a custom channel license. This can literally drop on of your respective redundant transmit rate packets leaving only one to make it to the other end, therefore increasing your noise unacceptability. Start with your frequency try changing it and make sure you have all the lower supported transmit rates enabled to allow the card to negotiate down during noise (that would at least tell you it was noise). If you can try charting your SNMP for noise floor and signal level (if you have a UB frequency native card and you are not using a frequency freedom version of the UB otherwise the noise floor readings are useless outside of the converter in the card)

Other than that, more detail what frequency? what output power? how long of a link? what are the antenna ratiings? VWSR? LOS?

Hope that at least gives you a direction..
