Bug#930271: iw: cannot scan if two cells on 2.4Ghz and 5Gz have same SSID

Show all headers | View raw

Package: iw
Version: 5.0.1-1
Severity: normal

Dear Maintainer,

   * What are you trying to do?

I'm trying to scan networks in a place where two cells on 2.4Ghz and 5Gz have
the same SSID.

   * What was the outcome of this action?

The scan returns only one cell (not the one with double frequency, a third
one), and subsequent scan return nothing. It seems that the scan itself somehow
crashes.

   * What outcome did you expect instead?

The scan would return all cells.

   * What's a potential explanation?

Somewhere in the stack, there is a confusion regarding having the same SSID in
both the 2.4Ghz and 5Gz frequency range.

Best regards,

--Martin
