Who I have the same questioned this topic

I've had the ARC-XCI55AX Gateway for almost a week, and the speeds are not what I expected.  😐

From what I was told in store, I would get at least 85 Mbps  and possibly up to  300Mbps download, 10Mbps upload.

But my speeds haven't been near that.   They've been averaging  70 - 79 Mbps  DL,  4-12 Mbps UL.     😧

I got plenty of signal with 3-4 towers close by.   My internet connection hasn't dropped at all.   It's only the speed that's the issue.

Anyone else having/had similar problems?   Could it be the ARC-XCI55AX Gateway I have is faulty, and needs to be replaced?   Any other reasons for this?
