Probably the ubiquiti routers wds1 and wds2 are misconfigured.
Could you please provide us with some information of the cabling? You mentioned you have connected the routers via lan cables. From which router/port to which router/port you cabled the routers?
Also, we have to check the router configuration settings of the ubiquti wds1 and wds2 routers. Please take screenshots of the settings you changed and open a ticket in order to investigate your issue: http://hotspotsystem.com/hotspot_help/new-ticket
