Poor wifi on Vero

Just received the new vero and had time to play with it.Firstly found the osmc skin not very bright and changed to the alternative Confluence skin which I am used to and is much clearer to use.
The ethernet connection works fine but Iam unable to use the wifi connection.Only shows one bar next to the router and separate solwise home plug with wifi.will not accept either password and keeps saying busy.No complaints about the picture quality which was free of buffering.
Any suggestionjs about the wifi please.

If it won’t accept the wifi passphrase please try running a manual update over Ethernet - some bugs relating to wifi passphrases being rejected have been fixed since RC3.
