@TraceyMG: Please try pressing the Volume Down and Side Keys together for around 10 seconds until the A20e restarts, as this will refresh the device and address any temporary issues that might have arisen. I'd also recommend unplugging your router at the wall for around 30 seconds, then plug it back in an allow time for it to reset. Once you've completed these steps, head back to Settings > Connections > Wi-Fi > On. Does the network show up in the Available Networks list, or connect automatically? If not, please head to Settings > General Management > Reset > Reset Network Settings, then head back to Settings > Connections > Wi-Fi to re-add your router. Let me know how you get on.
