HUB V3 IP Address not showing

Have ST Hub V3 connected to WiFi. Have now connected it to the lan using cable. Using an IP seach tool the hub ip address can be identified.

On Smartthings Groovy IDE the IP is not listed (0.0.0.0) and the Hub does not appear to recognise wifi devices?

I tried to do a Hard reset to add the hub with ethernet connection but I am unable to get the Hub to RESET. The instruction say to hold the reset pin until the indicator led does dark, i stays RED and when I let the pin go it reverts to Green??

Any suggestions?
Thanks
