Ring Door Bell Gen 1 connection issues (live view doesnt work)

Hi there, I am a new Ring user. I have purchased a Gen1 doorbell (allegedly brand new unopened stock). All looks imaculate.I have struggled for the last 4 days to get the thing to work reliably. I work in IT and know my way around networking/wifi and channels. My issue is simple, the camera is constantly offline, Had it online for maybe 30 mins tops.Motion detection, live recordings, and doorbell rings all work (Just cannot answer the doorbell).I can ping the device on the network so it is connected. Despite saying offline it is responding to ping.My setup is an Ubiquiti Access point UAP and a BT HomeHub5 running openwrt 19.07.7.It always sets up fine, tell's me its updating, then just fails.I have done the following, but all fails:* around 30 reboots of my router. Confirmed no firewall blocking outgoing.* I have confirmed there is a few access points around, but moved to free channels, as per recommendation on here, tried channels 1, 6 and 11. * I have setup a brand new SSID (Setup as Guest) and only the ring is using it.* I have purchased a cheap TP Link WA901N and tried using this. Again only device using it, still fails.* I have even enabled hot spot on my mobile phone and joined to that wireless network, while setting up from a tablet.* I have disabled Bluetooth, I have confirmed no known software that is on my phone that is known to cause issues.Any further help or suggestions anyway has would be great.Both my devices are android. Huawei, and Acer tablet. My wife also tried her Samsung but no joy.Kind regards, PaulI
