Hi @aboulfad
Thanks for the post and sorry that you’ve had some wrestling with getting the Muso on to your network.
The retrospective introduction of new available bands into the 5GHz spectrum has caused a lot of problems on compatibility. Currently it’s primarily a USA issue, but other countries are starting to introduce the higher bands, although wifi router manufacturers are hesitant to use the new bands by default.
As of the v4.3 software release (due this month) the Muso and Qb gain band C support in the 5GHz band, if the regional regulations allow use of that band. We follow the country code reported by the router which in turn selects the correct Wifi regulatory tables for that country.
On a side note the goal posts are moving again with the FCC opening up some bands in the 5.9Ghz zone. See:
