many thanks david cohran.

Excellent. Nice one David.

am really sorry to say the problems keeps comming back. when i disconnect the ezb and power off,it will not connect again. all other 5 robots connect perfect.i gess i have a bad ezb. so am gonna use the Contact Us if its not toolate.

i found when i reset engenius on pc,then ezb will connect to ARC. but when power of and wait 5 min connection is broken.

i managed to set the clock correct in engenius .but problem stay same. i fill in the Contact Us .

This same thing happened to me when I got my 1st EZB v4. I went the engenius route and made sure I had a strong signal for my EZB. However I still had the problem so I ended up getting a new router. I then manually assigned the EZB's IP address in the new router so the router's DHCP would give it the same address each time the EZB wanted to connect. That solved my problem (the same one your having).
