Wi-Fi getting half of the speed while my router is reporting that I have 800mbps.

Hi I got this router for like 3 years now and I'm noticing that my internet on my pc is around 300-400mbps but when i ran a speed test on my Archer C4000 in its UI its reporting 800mbps. What are the potential problems could it be that Im only getting half of what its reporting? Is there any solutions I could fix this problem? Thanks!
(The AC4000 is hooked up to a fiber modem)
OK, you switched the ISP then and/or the Service provided. I've had the same basically, my ISP moved us from 400/20Mbps to 1000/40Mbps.
When you change speeds, some devices retain the old settings... that is they might have set some internal settings and they can't reach the speed.
One thing to try is turn everything off, modem/router/devices. Then in order, Modem, router, devices turn each on waiting for each to fully come on before turning on the next one. Especially important on the modem/router connection.
Still, it might not change anything. In that case, the device could be holding onto setting. In each device you have to FORGET the network, especially if you used the SAME SSID names. Some devices you can't forget the connection, and in those, like on a PC you need to either delete it or create a NEW one.
Best way to fix that is to use a new SSID name, that too forces a change in the devices.
Another thing, you do not understand the meaning of the router 'speed'.
" I thought the router I have can do 1625mbps because it was advertised on the box. "
Well, that is not the true speed, but a Theoretical speed or a Connection speed. It is also a COMBINED capability speed. I assume you have the C4000 (https://www.tp-link.com/us/home-networking/wifi-router/archer-c4000/https://www.tp-link.com/us/home-networking/wifi-router/archer-c4000/) as it is an AC1625 router.
However you can't reach in terms of throughput 1625Mbps. That is the Connection speed, what your device and router connect at. The DEVICE and its IEEE 802.11 rating determines the Connection AND Throughput speed. Those standards are for the device speed letters, A/B/G/N/AC/AX. Each one has a difference throughput capability.
For AC, this is the maximum you can get:
===================
The theoretical maximum speed of 802.11ac is eight 160MHz 256-QAM channels, each of which are capable of 866.7Mbps, for a total of 6,933Mbps, or just shy of 7Gbps.
===================
Note what IS required, eight 160MHz 256-QAM channels. to reach the maximum speed. Now does your Device have that ability to handle a 160Mhz wide channel? Does the router put it out? Do both sets of antennea's put out 8 signals? Probably not.
Bottom line, you can't get 1.625Gbps with that router as the SPEED of the Internet.
I have an AX55 with an AX speed connection on the ISP's 1GB service. My network card (Intel's Killer AX1650i) connect to my router at 2280Mbps. The router is and AX55 AX3000 dual band...
On the web page for the router is this:
=========
Next-Gen Gigabit Wi-Fi 6 Speed—2402 Mbps on 5 GHz and 574 Mbps on 2.4 GHz band ensure smoother streaming and faster downloads.†

†Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Actual wireless data throughput, wireless coverage and number of connected devices are not guaranteed and will vary as a result of network conditions, client limitations, and environmental factors, including building materials, obstacles, volume and density of traffic, and client location.
==============
Physical Rates, NOT the Throughput speed. Like I said, I connect at 2280Mbps when I do a Lan Scan with an Analyzer... close to the maximum.
I'm on Windows, and I look at the Status of the connection via the Control Panel, Network Connections, and Right Mouse button on the Wireless connection and select Status and I see this:
That is the SPEED my network device is talking to my router, NOT the speed of the Internet Connection. Again, I have 1Gbps down... (which is impossible to get, 940Mbps is normal). I do have the AX device and my PC speed test is this:
This does vary as there are many things, like server traffic, that can effect the speed. I have hit 940 a few times.
I should also tell you my router is set to provide the highest signal, that is a 160Mhz wide channel.
If you want to learn more about the Connection speed and throughput, got to DUCKWARE DOT COM (TP-Link doesn't allow external links here so replace the DOT with . between the 2 words). Look at the first link, Wi-Fi 4/5/6/6E/7 (802.11 n/ac/ax/be) as it is technical but it does explain what you can get.
