Spectrum scan of 2,4 band

RouterOS The Dude
1

brings crash of RBs unexpectadly.. Tested on RB600 and Allix platform. Platform restarts, no error listed in log..

2

specrtum scan is only supported on a few wireless cards

Everything correct, R52N used (purely :slight_smile: ) Just for hint.. 5GHz scan has no such attitude.

Which RouterOS version and what wireless settings, please post.

It is 5B5 now on Alixes (more stable seems). Setting regular Nstreme dual.

Nstreme given to bridge.. thats it.. But it seem doesnt matter if Nstreme used or not.. May be somebody sugest 2.4 is not band to make scan :slight_smile:.. But, this is board for transvertors, so the freqs are like intermediate frequencies, and are not used outside the system. This way it serves as spectrum analyzer on 10GHz :slight_smile:
