If I plug an ethernet cord into the Fios extender, for a computer, will it give me the same performance as a hardwired connection, or do you lose something because it is through the extender. I am hoping it is the same performance as hardwired because it is through the cable line , even though it isn't through the primary router.
Yes and no. The coax feeding the extender is MoCA 2.0 so you will only get up to 400 mbps. If your internet speed is less than 400 the answer is yes. If you have the gigabit connection then no. Either way up to 400 mbps is mpre than enough for most things.
