I had FIOS internet installed yesterday and now I have been experiencing weird switching between the 2.5 and 5 signals on the router. Sometimes my MAC computer completely rejects the 2.5 and will only connect to the 5. This manifests as my computer rejecting my PW repeatedly. Then for no apparent reason the computer is find with the 2.5 signal. What is this and am I doing something wrong? I turned OFF the "guest" WIFI feauture to see if it would help with this. Thanks to anyone who can help with this.
