ROS5.2 dropping signal on a link that is -65

RouterOS Wireless Networking

Hi,

I have a link that is about 15km line of sight, signal is varies -65 to -69 but is so unstable that net is unusable.

Logs
MACADDRESS connected
MAC disconnected
MAC reassociating
MAC disconneced extensive data loss.

I’m using R52HN cards.

Any ideas why it would do this, tried diffirent frequencies including going to superchannel as test on a higher and lower frequencies, still no joy.

[EDIT]

Also, There is no other wireless devices other than the three on the mast. Thats in a 30km radius, so no interferance, it’s in the bush. (Kalahari)

I am going out to try and put grids in horizontal pole, see if that helps any

Let me also add there is a high power line behind the link, which should not affect it, distance to the power line ±600m but as I said behind the link, the other that shoots through powerline seems to be stable most of the time.
[EDIT]

Placed the grid’s in H Pol, Problem still exists, signal level -65 through -69 signal dropping, but have noticed that ccq drops to 15-20% when it does this.

Step One is going to be: upgrade to the latest ROS and re-test.

Did that, no change, I then replaced all radio’s at that site: 4 of em

I don’t know how 4 of them go at once, it was quite hot, but within limits for the radios operating temperatures.

It seems to have stabalised now

Did you try resetting the configurations of the radios before replacing them (using / interface wireless reset-configuration … ), and/or trying those same radios on different RBs? Sometimes ROS upgrades don’t entirely “clean up” configuration problems left over from older ROS versions. Installing a new radio would effectively start with a clean configuration.

Will retest radios, needed to get site back up, so did what I could.

Been there myself. For future reference: when a radio is doing something strange, always- try resetting its configuration, and then re-configuring it, before swapping it out. Depending on your options for accessing the box, sometimes it will save you the trouble of a climb, or a truck roll, or even of powering down.

Will do, and the day that I climbed there was kinda a storm on the brew…so didn’t really want to go up the tower, especially since it’s the highest point in like 100km2

Thanks for reply though

What wireless protocol are you using?

Try with NV2 if your not already using it.
