When plugging the MCK extender into my router, I cannot get a VoIP connection on the phone. I can connect, however, if I bypass the router and come straight off the modem. Using the router, I have no trouble getting a LAN connection on my computer but the phone just cycles through 65 seconds of retrying to connect and connect rejected. Are there any settings I can configurer to accommodate the phone. Without being able to use it through the router, I cannot function, as it shuts down my entire home network if I would be forced to use it without the router.
