My connection is now perfect but I am aware some people have problems. I did have an issue when I placed the hub close to a speaker and in a Wi-Fi black spot in my room, also after a power cut I have to re-pair my Roku. So my thoughts are that peoples issues are down to the local environment and not down to software in the hub. This is probably the main reason for the X1s as it has hardware changes for communications, “wake on lift” and a new font being the only other changes I can see. The X1(s) and U2 are advertised as Universal AV remotes not Home Automation remotes (go and spend £700 if you want that) so Hue in any form should be considered a bonus, personally I don’t use it (I did buy a couple but sent them back as I am not upgrading my phone just for their app). You do have a point about it lighting up randomly.
@husmoaschta: I'm not talking about new features. I'm talking about existing and not working features. The Philips Hue integration is a joke (not even finding all fixtures - any 5-bucks app can do that...). The Bluetooth-connection is not stable (not even within a radius of 3m, so I suppose it's a non-fixable hardware bug). And the remote is lighting up from alone randomly (that's annoying in a dark home cinema). All these issues are well known sincs several months. But instead of finding solutions, they come around with the X1S. Hmmmm....
