I'm out of ideas.
I'm supporting a deployment of a number of RouterOS based wireless nodes overseas. They were equipped with the Custom Frequency Select module, are a mix of RB200 & RB500 systems, and all have CM9 radios.
Before they shipped, I preconfigured them, established links between them, and tested the entire network out in the lab.
Now they're installed, and aren't working.
The AP is broadcasting it's SSID, and a Windows laptop is able to connect to it & transfer data from the SU's location.
The SU, when set to AP mode for testing, can be connected to with the laptop & transfer data.
The SU, when set in SU mode & pointed at the AP, sees nothing. The scan list is totally empty. I've tried manually setting the scan list value to a frequency range that covers the AP's broadcasting frequency, I've tried setting the SU's scan list to just the AP broadcast frequency, and I've tried manually forcing the SU's frequency to the AP's frequency, while having either an empty scan list or reasonable values in the scan list.
Nothing works. The SUs flat out do not see the AP. We've tried swapping radios in the AP, swapping radios in the SU, we've tried different SUs, both preconfigured & creating new configurations, and NOTHING works.
I've also tried setting one radio in the SU to an AP, and the other to the station, and scanning - they can't see each other, but once the mode is switched from superchanel to regulatory domain, they were able to see each other.
I've tried all combinations of superchannel/manual tx power/regulatory domain on the AP & SU, nothing seems to work.
Everything worked fine in the lab before I sent it out. There are different antenna cables at the deployment, but the fact that the laptop can see both would tend to indicate that they're working at least halfway decently. Also, a number of different antenna cables have been swapped in, everything is doing the same thing.
As I said, I'm out of ideas. Does anyone have suggestions? I don't tend to think it's software issues, but I haven't had much time to play with superchannel, and I think we've swapped hardware enough that unless all the antenna cables are bad, we're looking at software issues.
