I'm having this issue as well and it's driving me mad.
I've got a Neeo remote at home that works perfectly with a full Ubiquiti Unifi network. C4 don't recommend Unifi but it works fine even with micro-segmentation on the network. I've not even separated the 2.4/5 GHz wireless networks, and I've got the band steering of high performance clients turned on, and it has dropped connection maybe once or twice.
However, I've got a customer with a Neeo and a Draytek network - which C4 don't have an issue with at all - and the remote performance is so bad the customer wants to return the remote. The site has got separate 2.4/5GHz network SSIDs (although if the WiFi stack on the Neeo remote has been properly developed this shouldn't be an issue) and it still keeps dropping out. There's no issue with signal strength and my WiSpy doesn't detect any other hidden interference. I have tried talking to C4 tech support about this, have implemented all their suggestions, but nothing seems to improve performance or stability.
My last chance is to move one of the wireless access points to see if that helps. If I can't get this working the customer wants to return the remote for a full refund, which given that they specifically requested the remote (i.e. I didn't try and sell the remote upgrade to them), is going to be a tricky conversation.
If anyone has any other suggestions for what might help solve this issue I ma open to any and all suggestions.
