I have a fairly new tower computer with a built-in network RJ45 port. The motherboard has a Realtek PCIe GbE Family Controller built in that is supposed to get speeds up to 1GB but in the device manager it only says 100MB/100MB up and down. I have a fiber connection that was 600MB Full Duplex but is being upgraded to Gigabit fiber soon. Since my computer is upstairs I use a TP-Link R305 range extender that is supposed to be capable of up to 1.2GB. The signal is strong and I connect directly from that to my PC with a Cat6 cable, also high speed.
To eliminate the onboard network controller I bought a TP-link Gigabit PCI-E network adapter capable of 10/100/1000 MBPS. When I went to install I found that it uses the same drivers as my onboard network controller. It also shows 100MB. Speed and Duplex is set to 1GB Full Duplex. I am downloading at about 12MB/s and uploading at about 3MB/s which I have read is about the limit for a 100MB port. Because I have a strong signal and it is maxxing out with the range extender I feel I should be doing better.
Short of hauling the PC downstairs and connecting it directly to the cable modem is there anything else I can try to speed it up?
Are you logged in?
Have you tried reversing the polarity on the ballast?
On your range extender are you using 2.4G or 5G EXCLUSIVELY?
Also, is there a firewall or other software reducing your throughput?

As a test get a long cat 6 crosdover cable and connect the computers back to back to eliminate network bottlenecks and isolate the issue
Have you tried reversing the polarity on the ballast?

The muffler bearings are running hot.
Do you have access to the cable modem that would allow to make changes if necessary ??
The reason I ask is, the Ethernet port may only be capable of 100mb and if it can do 1gb it might be hard coded to 100mb and what happens is your cable modem and pc will auto negotiate to a compatible speed in this case 100mb
The only solution if the cable modem can only do 100mb is to upgrade to one that is capable of 1gb otherwise you are spinning your wheels
powerline adapters rather than range extender
Is there anything else connected to your extender ? If so, it defaults to the speed of the lowest device.
First thing I would do is work to isolate the problem. Turn off your WiFi on the PC, then plug your PC directly into the TP-Link router and check your speeds there. If as fast as you expect, then disconnect from the router, renable WiFi on your PC, and check your speed directly to the router. Again, if OK, then is sounds like the range extender might be maxed out. If slow, like originally via the extender, then the TP-Link WiFi router or settings are off.
I had a slow link through a TP-Link router. Problem turned out to be I had used an old CAT5 cable to link the internet modem to the router, and it couldn’t handle the higher speeds that both the modem & router were capable of. I separately had a problem with a router setting, where I had bandwidth controls set, and they weren’t high enough to support the higher data-rates the other gear was capable of - effectively throttling speed down.
10BASE-T: UTP category 3, 4, 5 cable (maximum 100m) EIA/TIA-568 100Ω STP (maximum 100m)
100BASE-TX: UTP category 5, 5e cable (maximum 100m) EIA/TIA-568 100Ω STP (maximum 100m)
1000Base-T: UTP category 5, 5e cable (maximum 100m)
The TP RE 350 has a 10/100 RJ-45 output.
So you are using WiFi to the range extender and hard wire to the computer? Then the bottle neck is the range extender. Look at WiFi 6 for greater range and speed. This should give you the range and speed thus replacing the range extender. Check you WiFi card speed capability 1st, may need up grading.

Are you sure the link is reporting 100MB, or is it 100Mb? THe case of that "b" is important.
100MB is roughly 800Mb, which is close to your expected 1Gb connection.
Most providers advertise in Mbps, rather than MBps because the numbers are higher. From your explanation, I think you are OK, though I would confirm the 100/100 up/down speeds (B vs. b).

I had a similar problem, and it turned out I was being throttled by my ISP. It was inadvertent on their part, but I had to prove it to them before they would fix it. It took two hours on the phone with a competent tech after I was blown off by other phone techs.
I showed them the problem by using a hard wired CAT5 connection directly out of their modem to my PC, with no router and no switches in the picture still had slow speed.
I heard range extenders cut the effective bandwidth at least in half, because they have to both receive and send the signal. Wonder if there is a bottleneck there.
Did you try rebooting? Unplug, wait one minute and- sorry, I couldn’t resist.
I also run cat7 cables for all the direct connection. (Upstairs all laptops run on either 5g WiFi or hardwired) and getting way more than you are.
Cat6 cabling might be an issue or it might be also the max limits on that RJ45 port too.
