I have a Swisscom internet box plus router connected to a VOIP telephone via ethernet. It works perfectly.
The problem is, when I try to use a Netgear 6150 wifi extender in another room of the house and plus the VOIP telephone in via ethernet, the telephone calls I make are no longer clear and they drop out every 2 seconds or so. I have been told that this is due to the wifi extender.
What are my options to solve this issue? Would the Swisscom Wifi extender work?
