Do you have any large building supply stores like our Home Depot?

We have technology markets here but local online websites often sell for cheaper. I noticed that there are different types of cables marked with S/FTP, U/UTP etc. Will the choice matter in my situation?
STP, UTP, FTP Cable When to Use Them!
As near as I can tell, the cable I use:
Cerrowire 100 ft. 23-4 Category 6 Riser Cable - Blue-2704-0144CR - The Home Depot
is just plain UTP or U/UTP unshielded cable. Any extra shielding certainly won't hurt anything, but it will make the cable more difficult to work with. For home use, I don't really see the need for any extra shielding.
I can assume that it's your cable. It could be possible that its your router instead, but if Ubuntu gets 1 Gbps, then it probably isn't. Try getting a new cable or re-configuring the ethernet setup at your house. It could be possible that Windows begins to detect data loss over a long distance transfer and drops to 100 mbps to stabilize the connection and prevent that data loss, which means that Ubuntu just doesn't care whether or not data is lost. My PC is rated for 1 gbps as well, though I can only get 100 mbps. This is due to my router being ISP provided and the PLC wall socket being total garbage. If your router is ISP issued you could be experiencing similar issues, though I highly doubt it. I can only get my 100 mbps due to the router's poor IP management and poor signal prioritization (meaning that the cable DVRs get the highest priority on the network, then wireless devices, then wired devices). But if I switch to gigabit wireless, I drop to 72 mbps (theoretical speed if router was unrestricted), again due to the router having limited speeds for certain devices (max supported speed to the DVRs, 17 mbps to wireless devices, 10 mbps to wired devices). There are also limitations on cables that can cause issues. If you have a CAT5e, good luck getting 1 gbps on any OS. CAT6 and CAT7 have lower chances of losing data at gigabit speeds as they came later so you might get better chances of getting gigabit speeds.
Interesting on how I have rock solid gigabit connections on several computers using those bad realtek chipsets and Windows 10 drivers.
Thanks for your opinions. As I pointed out, I almost found the weak chain. I think it is my Belkin ethernet cable. (This one) It is 5 meters long CAT 5e cable which can't sustain gigabit connection. I have two other 3 meters long cat 5e cables but unfortunately their length is inadequate. Interestingly the shorter cables can handle gigabit connections. I am guessing the cable I have is not good enough. I will order a new cable and will share the results once it has been delivered. In the meantime, I also ordered this wireless adapter to be able to connect to 5Ghz wireless network of the router. It's a shame that my notebook does not support 5Ghz networks. 1pcs Wholesale Store 5G Wireless Dual Band AC600 433Mbps 802.11AC USB Wi Fi Network Adapter-in Network Cards from Computer Office on Aliexpress.com | Alibaba Group
I've actually had the same issue on W10. Strangely enough W10 on a VM with a Linux Host gives the full 1GB transfer - no prob at all with CENTOS HOST with the full 1GB -- I really don't think this is a cable issue but needs some settings I suspect in the Network adapter.
I can see the change as the Green light on the Lan port (1GB) changes to Yellow (100 Mb) on Native Windows.
I don't use Long bits of LAN cable any more but I did have the problem in the past --although Linux seemed to be able to handle it.
Since I usually use Windows on a VM where the problem doesn't arise I'll leave the solution to those more experienced than me, I would check all those obscure parameters in Network adapter properties. -Take notes before changing so if you hose it up you can set it all back again.
In my experience unless the connectors are broken Cables very rarely are the cause of a problem - they either work 100% or 0% !!! -- Don't be mislead into buying hideously expensive cable --especially for short runs --I've seen stores in the UK convincing people to pay almost 100GBP / 130 EUR for an HDMI cable !!!!! -- the el cheapo ones work fine for normal lengths !!!!!!!. I even use one of those "expandable" ones you pill out of a reel -- thin - and never had slightest problem with Ultra 4k HD !!!!.
You mention things like 5Metres of cable --once you get into long runs then all bets are off as any cable will be lossy. Probably Linux handles the Signal Loss better- just don't know.
If your Notebook can't use 5GHZ networks have you thought of using a WIFI-->ethernet Bridge -- set an old (5GHZ capable) router to connect to your main router Wirelessly in WIFI-Ethernet Bridge mode and then simply connect a short piece of LAN cable to your laptop from the Ethernet Bridge router. You usually can connect 4 ports to a router. If your Broadband is fast enough this method has a technical Max capability of 433 Mb/s -- more than fast enough for most things, I use this method for running TWO NAS boxes as they are situated a long way from my cable router and I don't want long bits of LAN cable all over the house.
If your spare router doesn't natively have an Ethernet Wifi bridge mode you might be able to fix an older router by using DD-WRT

(Also running Wifi adapters on most Linux distros is messy --my NAS boxes (actually using HP gen 8 Microservers) both have two ethernet ports each so seems silly not to use them !!!!).
I'm surprised more people don't do this as the price of a cheap router is probably cheaper than cost of installing LAN cable all over your house --and it certainly keeps odd boxes away from Living room etc. I really don't want TWO NAS boxes running under my main TV !!!!. When I'm relaxing I don't even want to THINK about computers !!!.

Believe it or not, there is a difference between CAT 5e and CAT 6. They don't come up with new standards for no reason at all. That's like saying it doesn't matter if it is a USB 2 port or a USB 3 port, USB either works or it doesn't. Windows will likely be more sensitive to a lesser quality network signal because Microsoft sets standards for performance. Who sets the standards for performance for Linux?
One must remember - there is a whole lot more to network performance than just what the connection speed is. The quality of the connection matters just as much.
