A: sounds like your modem speed is correct, as most ISP's deliver a certain percentage of overspeed (i pay for 400 and get 450-460 consistently)

B: the desktop, wired directly to the first Deco via ethernet, should be seeing 500+ at this point. my desktop is sitting next to one of my ethernet backhaul accesspoints (and is wired to a switch) and i can see the full 450-460 on a speedtest both wired and wirelessly).

C: I have two hard wired Deco's on my first floor and i will see 350-450 on my iphone, macbook and ipads when i do a speedtest (yours may vary depending on where your Deco's are and any local interference. However, half speeds can be expected and somewhat normal over wireless given placement, walls, floors, obstacles and interference. you may be able to troubleshoot this a little. (upstairs i have my 3rd Deco for instance, and its wirelessly connected to my downstairs units. its speeds are between 225-350 depending)

D: speed on the TV seems pretty low, but through the walls, i wouldnt be surprised.

the only thing that bothers me of your issues is A. theres no way you would be seeing those speeds wired directly to the first Deco. i know the ethernet card is old and is gigabit rated, but i bet thats your bottleneck.

I tend to agree re the Realtek, but unfortunately, it's not a card. It's built in to the mother board. Maybe I could get a card. I'll check.

  @Cuebeb I spent some time with Spectrum rep on the phone at noon yesterday, then a tech guy in person last evening. While on the phone, I saw 500+ Mbps at my desktop. But shortly thereafter, a few minutes, after I let them off the phone thinking we had fixed the issue, back to 230 Mbps or so. The tech guy last evening measured 500+ into the modem, the same out to the first Deco, but only 230 at my desktop after the Deco M5. Something is wrong with my Deco.
