Hi There.

  I want to use the RE305 as Access Point but everytime I connect it to the ethernet cable the internet connection drops on my main router MistraStar model GPT-2731GN2A4P. I've double checked that the DHPC is turned off to use the Mitrastar DHCP server but no luck. I've also upgraded the firmware to the lastest verstion and still the same problem: just plug the ethernet table and the internet connection drops in my main router. Disconnect the cable and few minutes later, the internet reconnects. Inreresting that I have another TP-Link extender model WA850RE working as access point without any problem connected to the same router. 

  Have  anyone had this problem? Any hint how to solve it? 

Thanks in advance and best regards...Claudio.
