ARC Connection Question

Hi everyone,

I have been kept away from this forum (and robots) for a looong time but I am back again So, I try to connect ARC with my EZB-v4. The problem is, it doesn't work...

First, I have looked carefully at the tutorial and everything is clear. Second, it doesn't seem to be a wifi issue :

• in AP mode, I can see my EZ-B v4 0282 wifi network in windows (seven) and connect to it. I can then access to http://192.168.1.1 but when I go to Diagostics, I can hear no sounds. When I try to connect in ARC, the blue light stop to blink for 4 seconds and I have the "could not connect to the EZ-B" message. So, I go to Client mode....
• in Client mode, the EZ-B blink green and It seems that it do not connect to the network (no message of success from the EZ-B). Yet, in my router configuration panel, I can see the EZ-B, and an IP address is assigned...But again, when I try to connect in ARC with the assigned ip, I have the "could not connect to the EZ-B" message and if i try to detect the EZ-B with the scan option, it finds nothing.

I am not a specialist, but it seems that my PC, my router and my EZ-B are able to communicate and see each other, but ARC cannot connect with the EZ-B. And I cannot see why...

So any help is welcome. Thanks.
