@Tony Yes, I have tried 3 different devices.

@ArcherC8 Router has latest firmware. I am getting 100 meg upload over wifi, just not download. I can stand next to the router and see little to no improvement. Appears download is being throttled...

Just installed the C4000 and my wifi speeds are half my wired connections. I have 100meg fiber but only get about 40 to 45meq wifi. Get twice that wired. Any help appreciated.
