Bit of a strange issue;
I have a Roku 3 with enhanced remote (no channel shortcut buttons)
The Puck and Remote have been working fine for the last couple of years, through multiple Wireless Routers and Access Points and I have experienced precisely no issues.
I recently ran Cat 6 cables throughout the house and went to use my Roku via ethernet connection purely to help avoid wireless congestion and the stability that comes with an wired connection - not that I'd had any issues anyway!
Long story short - as soon as I use the ethernet connection my remote will not pair with the puck at all. I can use my phone app to control and watch perfectly, the Roku is pingable and otherwise works perfectly normally ruling out any immediate connectivity issues with the ethernet run.
As soon as I switch back to wireless the Remote pairs and works fine again!
At this stage I can then swap to wired and the remote will stay paired and operate fine until...... either the puck is rebooted or after what i'm guessing is a sleep/wake cycle i.e. overnight.
I have reconnected the puck to WiFi and remote has continued to work fine - its just bugging me that I cant use ethernet!
I have tried factory reset and the remote repairing steps numerous times but no joy. The remote just continuously blinks the green light. Connect to wireless again and boom - pairs straight up.
In my limited knowledge - I understand that the Roku uses a direct WiFi connection to pair with the remote - (the puck broadcasts an SSID that the remote connects too). I'm wondering if there is a defect that means the pucks wireless antennas are being held off when connected via ethernet. Its only when the Roku tries to connect to a wireless network that the antennas are brought up?
Anyone got any other ideas? Have I missed anything obvious?
