I have a 100/100 fiber circuit from twtelecom. That we just installed previously we had comcast cable at 50/10.
Once we switched over to fiber my speed test went down to around 20 meg down.
with cable we was getting 50 to 70down.
we have tried both full duplex and auto with very little difference.
anyone have any idea how to get proper speeds. Already have cust. complaining on the slower speeds
