I do not know what else I can do! I have replaced my extender, replaced and upgraded my router, went through the new setup of the router and STILL have NO PHONE SERVICE through the extender! The same problem that EVERYONE else has reported does not seem to get resolved, no matter who asks. I have tried every link available, been through every trouble shooting step there is, and NOTHING HAS HELPED! I FED UP! Can anyone offer ANY help at all. I am sure I have tried everything but if you have any suggestions, please let me know.
