Desktop wired ethernet connection half the speed of my cell

Specs: Windows 10, i7 6700/12 GB RAM
So, I'm trying to figure out why the Internet speed of my cell phone gets over 200 Mb/s using speedtest.net but my home desktop PC that is wired gets less than 100 Mb/s. I have an Asus RT-AC3100 router. I've verified it has gig ethernet ports. I kept suspecting the ethernet cable between the router and the PC. Well, my ethernet cable runs from the router to a switch at my desktop. I then have the switch hooked to both my work and home PC. The switch is a Gig ethernet switch.

The wire going from my router to the switch, I wasn't sure if it was CAT5 or 5E. I know CAT5 can't reach a gig. So, I bought a 50 ft CAT6 wire and just ran it from the router to the switch. The wire from the switch to the desktop is CAT5E. I just ran another speed test and I'm getting 90 Mb/s. (I just got over 200 Mb/s using my phone over wifi.) My port speed on the PC shows it has a gig connection. I couldn't figure out a way to see what the port speed was from the router to the switch (It's obviously not a smart switch.) So, I just unplugged the CAT6 wire from the switch and plugged it directly into my home PC so the CAT6 wire was going direct from the router to the PC. The port shows a 1 GB connection. But, I just ran another speed test and I'm getting between 70-90 Mb/s. I just tested my work pc too that's on the same switch. It also shows a 1 GB connection. Speed test was 70 Mb/s. Any idea what I can do to get the full 200 Mb/s over the CAT6 ethernet cable?

I actually already read that exact web page before posting this. I've already tried everything the page suggests.

If not using a cat 5e cable, have you tried?

if using a power surge board, bypass the board & connect the cable direct

I'm using cat 6 which is better than cat 5e. I'm not going through any surge board.

"I'm using cat 6 which is better than cat 5e"
My googling shows in some cases, the 5 was the better cable.
I would see if I could borrow one.

Looks to me that the Qualcomm Atheros Killerâ„¢ Network Manager is a bandwidth limiter. I don't want to limit the bandwidth to my apps any more than they are. I want them limited less!

JohnW, you might want to check your sources.

CAT5E can handle up to 1 GB/s. CAT6 can handle up to 10 GB/s.

Exactly, if you had been using something like that, I would have suggested dumping it.

Yep, but in some cases, in the comments of other forum posts, the 5 worked better. Doesn't make sense I know.

Any differences would be negligible. As far as patch cables go, Cat5e and Cat6 perform similarly enough so as to have no appreciable difference. I've worked extensively with Cat5, 5e and 6 for years. I've pulled, punched and tested miles and miles of all the above and have used hundreds, if not thousands of preterminated patch cables of both 5e and 6 and found no real difference in either case.

For anything above 1 Gb we use fiber optics but this is typically going to be out of the average home users price range and completely unwarranted in any case except for bragging rights.

What is the bandwith you're getting from your ISP?

A network is only ever as fast as the slowest part of it. So, if your ISP is providing 100 Mbps bandwidth then that's all your're going to get from the internet, regardless of whether or not your internal LAN is all 1 GB.

I live in a small community and my ADSL package is 5 Mbps down and 1 Mbps up (for now, there's talk of 1 Gig......I'll believe it when I see it!) so my speedtests from home are only going to be 5 Mbps even though my LAN is all 1 Gig.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

I have cable internet and they advertise 200 Mb/s. My cell phone, using speedtest.net consistently gets over 200 Mb/s. My desktop wired using Gig ethernet gets less than 100 Mb/s. I totally get that my Internet will be a bottleneck. I won't get a gig throughput for my Internet. But I should be getting the 200 Mb/s when my smartphone does over wifi.

Does the speedtest.net select the same (test)server on PC and smartphone?
Any proxy set on your PC? Or VPN?

Sluc, you are right. I never thought to look to see what server they're connecting to. I just changed the server on my PC to match the server it's speedtesting to on the phone and I got 222 Mb/s! Cool! Thanks! Wonder why the other server is so much slower? You'd think they'd fix that if it's being used to check Internet speeds.

Speedtest.net does not own the machines running speedtest.net app. ISP'a and perhaps datacenters or other network operators have an account with speedtest.net to operate the app/server. It is a way to test the network speed of their customers.

Depending if the machine is dedicated to speedtest or is running other services and on the current network conditions, results will differ. Do not stare yourself blind on ONE speedtest server. If the server is within your ISP, the result should show the subscribed network speed. Once you go outside your ISP network, speedtest results can vary widely depending on current network conditions between your and the speedtest server.

Some Speedtest systems allow the user to select a single dedicated path for the test; others to use only the multiple path option. The latter usually is faster than the single path - at least that’s been been my experience.
