SXT - Speed Issue

RouterOS Wireless Networking
1

I have two SXT’s linked together about 2KM apart. I have upload two seperate images from these units;

The problem I am having is as follows; If I leave the SXT’s on default speed selection I get a connection of 243Mb/65Mb with a 148000/55000 P-Throughput and a decent CCQ (90’s). The DB rating on both connections are in the low 60’s. The 65MB never increases no matter what freq or even at 100% CCQ

If I ratelimit the SXT’s as per the second image uploaded, I get a 150MB/150MB Connection with similar CCQ and DB rating as above. As soon as I unlock one more speed rate the RX drops from 150Mb to 65Mb.

Why would the SXT drop one link to 65MB ?

Any Ideas on this? Help would be greatly Appreciated

the data rate will go down if there is no need for transferring a lot of data.

The Issue remain constant, Even with a Bandwidth Test running. It will never Unlock over 65Mb with default rates enabled.

factors to recheck:

antenna alligntment on both side
tx power
make sure to choose right “empty” frequency

thats all :slight_smile:)

Can you provide your settings to achieve the 150/150 rates? I’d very much like to duplicate this issue. Please be as specific as possible (what protocol your using, etc.). … and what interface are you programing your SXTs with (Winbox, ssh, etc)?

Thanks!

i doubt so much to get TCP data transfer 150Mbps / 150Mbps (TX/RX) ..
since in the other topic i already post, i only got 70-80Mbps single way (TX only) of TCP data streams

This is linked to http://forum.mikrotik.com/t/hardware-support-sxt/44288/1 and is Exact same hardware used for the testing from the original link, now on a avg 1.8KM link (pure LOS) http://www.wug.za.net/newlos2.php?fl=22375&tl=17726
