I have two P2P links (one side bridge, other side station wds) with SXT-5HnD equipment (latest release 5.7).
They are connected from one site to diferent directions like in picture: Now:

Link 2 (red) is link that has worked normally before installing Link1 (green).
Device 2 of link 1 is turned off.

When Device 1 of Link 1 (green) is turned on I have problem with link 2.
Here are configurations of both Bridge sides (Device 1's in the middle).
NOTE: It should be Link2 Device1 on right picture

First I had them on 60 MHz distance but I had problems. I put them on 5560 and 5240 (just for test), and sam thing happens:

I had problem with link 2 and it constantly losing connection.

I can show you graph for over time, just to see visually. I upload daily and Weekly graph. Red square is OK (follow brown line on top of the graph in Weekly graph), and after installing Link1 problems appear. After turning off Link1 Device1 (Device2 is off all the time) Connection is OK (I've tried few times, see on graph).
What can cause this interference on different channels?
I can send whole configuration if you want.

Can you post your wireless scan with both radio's on from both units.

Hi,

What happens if you switch off link 2/device 1? Does the other link still give you problems?
Also, what is your logging showing?

Rgds,
Mark.

The problem may be that the radios are very close and are saturated the lna rf card, I recommend separating them a bit or use some metal grille as shielding.

Hi n21roadie. Here it is, although I use free spectar (if you think that's because of some other station).
Red is mine problematic link (5560). Green is my other link that interfere.

Hi Mark. Unfortunally I don't have power at that site (link 2/device 1) so I can not switch it on.
But as I see, problem is regardless that link (just depending on Device 1). Probably would be same situation.

Logging say:

Oct/13/2011 07:33:51 wireless info 00:0C:42:88:22:D3@wlan1: disconnected. control frame timeout
Oct/13/2011 07:33:56 wireless info 00:0C:42:88:22:D3@wlan1: connected

hi mgutz2! That might be it. I will separate them about 1,5m today and give you back info.

I won't be able to remove it in next few days... I will return info is this solved my problem when I move it.

Here is feedback: I move units 0,5m from each other and now it's working good (for last 3 hours).
I didn't test minimum distance but I hope this info might help to others...

Thank you mgutz2 for your advice and other for your interest.
If I'll have any problem regarding this over the weekend I'll let you know...

For now, this is Solved.

Link 1 is now UP and running, and it's all fine between them.
