I've had great difficulty setting up my 2 CPE210's but got there in the end after watching of of the easiest video's on youtube showing step by step ins. on setting up the CPE's. They are no more than 30metres apart as I needed wifi in my man cave. the AP is wired from my switch box & the client is on my man cave. Once setup, all appeared well with all LED's lit up on both CPE210's I then ligned them both up. The AP LAN wired on my pergola & the Client from my Man cave. What I have noticed on the Client side is that the LED's seem to intermitently come full on then off every 20/30 seconds. I'm assuming this is not normal.  The main thing is. I'de like to add a small router, namely a WavlinkWN578R2 which can be set as Router/repeater or access point. Thing is. I cannot seem to be get this to work, whatever setting I choose. I have a LAN cable from  the Client Side of the CEP210 to the Wavling that has LAN &  WAN/LAN. I currently have this end Plugged into LAN.  Im no expert so would appreciate any help with setting this up.  Many thanks all. Tony
