I have the 2i and haven't had any problems with connections or updates. SMB is the file sharing protocol they use which has been around since the 1980's and is still widely used in small networks.
Problems with Bluesound Vault and PC app finding Node2 that are wireless
Does anyone else have this problem? My PC is hardwire LAN to the Bluesound Vault2 and the wireless router. The two Bluesound Node 2's are wireless. About 50% of the time, the Bluesound App on the PC cannot find one or both of the nodes. I have the same problem with Roon as well. It is very frustrating but I don't see anyway out of this.
