XB8 and wifi channel change

I've read most forums and I see the XB8 is managing channels automatically. Is there any way to turn off the auto manage so I can try a different channel. I am trying to troubleshoot a camera with connection problems even though it has a strong wifi signal. I was thinking it might be neighbors interference and would like to see if a different channel would help. unfortunately I haven't found a wifi scanner app that works on I phone showing congestion by channel but I know a lot of gateways choose 6 as default channel and wanted to try a different one
