We've a regular Plusnet fibre but due to being over 3 floors the deco mesh system really helps. I've set up 3 decos. We've now got a really strong signal all through the house. To prevent WiFi conflicts I've turned the plusnet WiFi off so everything can connect with the decos' WiFi. The mini HomePods had previously been connected to the plusnet WiFi and had played via airplay just fine (although the Plusnet speed from the router wasn't as fast as via the deco), once set up with the Decos, I'd had to keep switching my phone's WiFi connection back to Plusnet in order to use the HomePod which was frustrating so now the HomePods are all connect to the Deco mesh (now I've turned the WiFi off on the plusnet router) - but now we find that when playing music via airplay it constantly pauses or drops off completely. So the situation seems that it's fine running airplay music to HomePods via  the Plusnet from iPhone and won't run properly via the Deco. But I don't really want two WiFi networks running- any suggestion welcome please? Thanks in advance
