Network Server Subbands in US_902_928

I have the Chirpstack Network Server configured as follows:


However, the network server only responds on channels 8 through 15, which is subband 2. No matter what channels I configure, it only answers to subband 2. The network server responds to other configuration changes, but not the enabled_uplink_channels setting.

What am I missing?

That is driven by your gateway configuration. It sounds like your gateway is configured for US sub-band 2.

OK, I’ll look at the gateway, but that brings up a new question.

If the sub-band is configured somewhere else, why does the Chirpstack Gateway Bridge have the sub-band settings in it? What purpose do they serve?

See this thread, it has some good history on how that used to work and how it will work in the future:
