What was the actual problem?

the problem is that nobody in this forum can help you in problems like that… or ain’t nobody want to help you.

now seriously: big noise arround ap. on frequency quite different from our. problem solved with bigger dishes, sr5 replaced with xr5 and nstreme removed from link.

thank you for interest.

I am having a simliar problem on a PtMP system running XR2s to Compex 802.11g clients in 10mhz channels.

So far turning off “The Dude” helped the problem. However, I have seen a few clients recieved signal at the AP drop by 10db on occasion still.

I am pretty sure the volume of traffic being lower since shutting off Dude has helped. I am not saying Dude was the problem, but my problem occurs much less since shutting it off.

I’m working on finding the actual problem still, but my link is 100% better now. No disconnects for 48+ Hours.

Any idea why nstreme was causing that behaviour? Did you tested the setup with the bigger dishes, XR5´s but WITH nstreme enabled?

  • We are experiencing similar behave on a 53Km PtP link with Xr5´s and nstreme, I haven try it without nstreme since they say for those kind of shots nstreme is necesary … mmmh
