Just purchased the Arc/Sub3/2xOne set up and just found out that this Sonos system cannot connect to a wifi router that uses LTE (4G) as its internet source. It makes no sense to me as the speeds are comparable to boardband, it has enough speed for 3 people to use say Netflix, youtube and scroll social media at the same time. In near future I will update the Router to a 5G one which will have speeds of up to 100mps+. But even as it stands the Sonos system would configure with a 5G router.
And unfortunately where we live does not have the option for the traditional fiber/Ultra broadband etc.
It is a shame as I was really looking forward to having this Sonos set up.
Before I return it, I would like to know if Sonos are intending to do any updates that would allow users with a LTE router register and use their products?
