HT 5gh band change

Hi, could support please tell me the channel numbers the Arc uses to talk to the surrounds? It's playing havoc with wireless devices killing speed and causing disconnection. If the Arc has been designed to use a specific range of channels I can create a new 5ghz network with a fixed channel outside of the HT range the Arc uses. I read some old posts where people have fixed the Arc to 52 but I can't find a way into the system to change it, just it's 2.4 for router connection. I have transferred my system to a friend so I need a permanent fix. Ethernet is not an option if that's one solution. 

Thanks.

Many thanks I will check his router, pretty sure 2.4 will be 20mhz as I've never seen a router set to 40 by default but his 5gz maybe at 80, we have 900mb so they might come set at that.

 

Edit, actually it looks like 40mhz can only achieve 200mbs so it's almost a certain it comes set at 80. I may have to let him down on his max attained speed to fix the problem. I know 200 is plenty but I deal with customers every day who complain about not seeing there max speed on a speed test, I fit Ubiquity as part of been an AV installer but not on a Comercial/enterprise level.

Tell your customer(s) that wireless network performance is not about some random speedtest number at some random point in time, its about overall efficiency, reliability, stability and customer experience.
