Slow speed on Fire TV 4k and PC
I've had an AT&T U-verse in my apartment for over three years, on the Internet 50 plan. I have four devices hardwired directly to my router:
Roku TV 4k
Fire TV 4k
My Windows 10 desktop
PS4
In my Roku TV settings, it says I have 50 Mbps, and I'm able to view all content fine there. However on my Fire TV 4k stick, I'm lucky to get 20 Mbps, and I can't view 4k content. I subscribe to an IP TV service called ilml.tv, which works on my Fire TV, and it buffers frequently. My desktop PC has the same issue. My Playstation is also slow, but it's less of a priority.
Any ideas why my Fire TV and PC are slow? I bought a new Ethernet cable and even switched router ports to no avail. I even tried a factory reset on the Fire TV and restarted the router.
As of 9/19/20...
- disabled IPv6 under Settings > LAN > IPv6
- changed Ethernet port config to 100BaseT/Full-Duplex
- Switched to Google DNS (8.8.8.8 and 8.8.4.4)
Any other suggestions?

You have a single line and must have the VRAD sitting in your lot, or next door, based on the attenuation and therefore sync rates. You could qualify for 75 Mbps without another pair and with an additional pair, if they do have the port available, 100 Mbps should be no problem at all.
However, this will not make the connection to your FireTV any faster, because it's not the line that's limiting you to 14Mbps. The other thing I'll say about the FireTV is that 14Mbps may be sufficient for everything other than downloading apps. Finally, I located this reddit thread which seems to indicate this is "normal:"
https://www.reddit.com/r/fireTV/comments/jqd8gw/firetv_speed_test/
I offer that with a dash of salt. A note is that both of the USB/Ethernet adapters you have used are 10/100, meaning they cannot transfer more than 100 Mbps, and note that 100 Mbps per second is 12.5 MBps. If any tool you use happens to report in MBps, then that is the answer to the question.

Are you watching the same content at the same resolution on the FireTV 4K as you are on the Roku?

Not at the same time of course, but yes. I tried the YouTube app on my Roku TV and it played 4k videos fine at 4k resolution, but when I do the YouTube app on Fire TV I can *maybe* get 1080p or usually less.
I even downloaded a couple of speed test apps for my Fire TV and they both show me getting between 13-20 Mbps.

You have a single Ethernet cable running directly from the Gateway to the FireTV 4K, or are you going through walls, etc?
I can't think of what would make an Ethernet-connected FireTV stick report any less bandwidth than an Ethernet-connected Roku. You could try swapping the two devices and seeing how they behave in the other location.

It's all basically in the same room, so yeah I have a separate cable going from the router to each device just under a rug (four cables total). Four ports on the router all in use

Yes I've tried switching cables though I might try that one more time tonight. It's not the app on the Fire TV. Like I said I installed two different speed testing apps on the Fire TV and they both reported download speed of less than 20 Mbps. Some people have been complaining about the latest Fire TV OS update, but I'm not sure how that could affect speed. Also my PC's Internet is slow too.
I might consider upgrading my Internet service from the 50 plan to the 100 but I wanted to try to rule out anything local that could be the bottleneck.
I'll try the troubleshoot and resolve tool tonight as well

HI @marcnm, we are happy to help with your slow internet concerns.
In many cases, your TV and internet enter your home through the same terminal.
We suggest that upgrading may be the right solution to your concerns.
Thank you for contacting us on AT&T Community Forums!

Yes but I only have one physical TV. It's a TCL 55" smart tv with Roku built in, and then I have a 4k Fire TV stick attached to it. I have one Ethernet cable connected directly to the TV, and then another Ethernet cable connected to the Fire TV device.
