So sorry to bother you all on this but I too have the same Verizon Extender that has aquired the GPS and all lights are blue but since changing ISP's, I cannot get anything that resembles a clear outgoing or incoming call, frustrating not only myself but anyone that I am attempting to call. When making a call i can see that it is going thru my extender to my router but nothing but garbled voice in an out but mostly out (upload). I have 26/3 up/down and can prove the speeds but still nothing but garbled outgoing voice since changing to my new ISP. Any advice guys would help. I cannot call out to ask Verizon or Samsung or anyone else for assist. The extender has worked well for years but now that I have changed ISP's and they provided their router I am stuck with the above problem. Very Frustrating!
