Question Ethernet download at 10mbps but upload 20-30mbps in a 1 gbps connection

[chawlie33]

So i'm living in a dorm/hotel and there's an ethernet plug in the wall, i plugged to my pc directly and also tried to use a fast router in between the both and still get the same result.
https://www.speedtest.net/result/14460403417.png

The ethernet status says it's 1 gbps but all i get is 10mbps, i know for sure that the speed from ISP is at least 100mbps, since other people I've talked with had higher download speeds than mine (1.3 mb/s on my pc and 11-12 mb/s on their devices). Even wifi is working around 100 mbps on my phone when i do the speed test it's fine there.

Mobo: Gigabyte b450 gaming x with 802.3 network adapter, Realtek Gaming GbE Family Controller (latest version 10.63.1014.2022)
Running windows 10. 19045 enterprise x64 (fresh copy, was same problem with the version before this)
Link speed: 1000/1000 mbps

What i did so far:

• unplugging, restarting, clearing circuits
• used different cables, checked their insert points, all straight, the plugs on both sides are not damaged
• updated network drivers, manually removed them and manually reinstalled (also automatically through windows)
• tried all settings for duplex - from 10mbps to forcing 1gbps and also auto negotiation
• tried disabling auto disable gigabyte and LSO and all that
• i tried to run all the commands to flushdns and scan for corrupted files and disabling auto tuning
• i removed vpn, disabled proxy, energy saving
• updated bios
• tried to reset network from windows settings
• checked the colors on the motherboard ethernet port, all according to manual is working
• tried netsh int tcp set global autotuninglevel=normal
• used the troubleshooting option from windows- no issues detected
• downloaded Realtek diagnostic utility and ran the tests, all good no trouble
• Updated windows
• I dont have any other anti virus except windows defender, i turned it off and on but no improvement

- it's been 6 hours and im trying to find a solution, nothing worked yet

Before further blaming your pc, ask to try it in another dorm to rule out the possibility of it being something else. Like the cable inside wall or your dorm being bandwidth restricted somehow.

And I will add the following:

1) What was the reason for installing your own router? If there is already another router serving that wall outlet then there will be problems. Double NATing etc.. Make and model of "fast router"?

2) On your PC are you sure that only one network adapter, either wired or wireless, is enabled? The wall outlet indicates that you should be using a wired connection with the PC's wireless network adapter being disabled. Only one network adapter should be enabled.

3) Disable IPv6 on the PC. That may prove helpful.

4) Run "ipconfig /all" (without quotes) via the Command Prompt. Copy and Paste the results into a post.

5) Run "ping 8.8.8.8" via the Command prompt. Post those results as well.

I've asked people living in the 4th floor of the same building and they are getting 10-12 mb/s download speed while me on the ground floor getting 1.2mb/s (capped at 10mbps for some reason)

Tried this because other people said it would be helpful to try, it didn't help though haha regardless of it's speed and model so im gonna return it anyway

2) On your PC are you sure that only one network adapter, either wired or wireless, is enabled? The wall outlet indicates that you should be using a wired connection with the PC's wireless network adapter being disabled. Only one network adapter should be enabled.

The outlet has an ethernet socket that goes directly to my pc via a cat5e cable - it's intact !

3) Disable IPv6 on the PC. That may prove helpful.

tried this and it didn't work

4) Run "ipconfig /all" (without quotes) via the Command Prompt. Copy and Paste the results into a post.

"ipconfig" indicates that IPv6 is still enabled.

Also "ipconfig" does not seem complete - are you sure that you copied the full results of "ipconfig /all"?

Ethernet cable - understood but you must ensure that any network adapters (wired or wireless) other than the Realtek Gaming GbE Family Controller adapter are disabled.

Try running "pathping 8.8.8.8" and then "tracert 8.8.8.8" via the Command prompt.

Pathping will require a few minutes of time.

Post the results of both tests.

= = = =

Where did you get or who provided the Default Gateway IP address and subnet mask?

Contact whoever is responsible for the wall outlet and the wiring between the wall outlet and the patch panel.

Could be a poor connection in the wall outlet, a problem cable run, or a poor connection at the patch panel.

- It's set automatically as soon as i plugged the ethernet to the wall, i didn't change any

Contact whoever is responsible for the wall outlet and the wiring between the wall outlet and the patch panel.

- Yeah, it will take sometime for them to come and check but the outlet though so i'm trying to figure it out before

Could be a poor connection in the wall outlet, a problem cable run, or a poor connection at the patch panel. << this is also what i'm thinking because i used the same cable and pc in a different apartment and there was no trouble as such

In the meantime double check with the IT staff that your default gateway/DNS server is indeed 172.16.128.1 with a subnet mask of 255.255.240.0

Also tracert shows some problems with hops 3 & 4. Where those hops are with respect to the schools network/ ISP etc. I do not know.

Someone else may be able to look at the results and make further comment.

= = = =

Other things to do:

On your system run the built in Windows troubleshooters. The troubleshooters may find and fix something.

Also run "sfc /scannow" and "dism".

Could find and fix some corrupted or buggy file.

Being in a dorm/hotel means that it is very likely that someone has probably added other devices or made unauthorized changes in order to work around school rules and policies. Or otherwise attempting to improve speed and performance.

The school IT staff should be able to check that out.

How can i fix the loss in 3 and 4?

So I will assume things like tracert are in private messages. It is best to post all things to the forum, I do not ever look at my messages and there are many people that can help since nobody sits here 24x 7.

You can't do anything about anything outside your room but what you would want to do is compare the tracert from your machine to the the machines you say work well. Not sure you would see anything since it is very rare to have multiple routers in the house and tracert only sees routers and not switches.

My guess would be there are a number of switches between your pc and the house router. The connection between your pc and the switch might be 1gbit but the connection between the switch and the next device, router/switch whatever, is running at 10mbps. This is only a guess and you would have to be able to look at the equipment in the house to know if there is a issue.

The results are in links in Post #7 (Expanded). No PM's. Not sure why the links are not visible to others

From Link #7:

"ipconfig" indicates that IPv6 is still enabled.

Also "ipconfig" does not seem complete - are you sure that you copied the full results of "ipconfig /all"?

@chawlie33

Please copy the tracert and path ping results shown in the links and paste the results directly into a new post.

In agreement with @bill001g - all results should be posted in the forum. Regarding the losses in 3 & 4 I think it best if others have a fair chance to see the tracert and pathping results.

 

[chawlie33]

It's solved, i ended up trying a range extender instead of a wifi router, connected it to wifi and pulled an ethernet from the range extender to the pc and it's good now, Thanks both of you for your help! I'm sure something is wrong with the socket in the wall like you suggested. For now, i won't be needing the wall socket as long as the range extender is working fine. Getting 50-60 mbps which is nothing crazy but so much better than the 10mbps i was getting before!

Can i request that the thread should be deleted? or at least the posts with my settings ? <3

 

[bill001g]

If it works ok then you are good. If your pc has a wifi card it is about the same thing. Using a range extender the way you are is about the same as using a wifi nic that is attached via ethernet rather than USB. The ethernet does not buy you any real advantage in this configuration.

If you have issues with lag in games you might consider moving back to the wall jack while you play games. Games need very little bandwidth but are greatly affected by the latency spikes you see in wifi.

There really is nothing in your post that is a security concern. All the ip you are using are private IP and many people use the same ones. Even a mac address is not actually unique, if you were to buy 1000s of the same laptop like a company does you will find duplicates. Mac addresses also never leave your house.

The only thing you have to be somewhat careful of is the IP of your house. Some idiots would denial of service attack you, but you did not post your IP. At best someone might guess what city you live in.

 

[Ralston18]

The thread will remain as is - no need to delete. As stated there are no security concerns.

FYI:

https://www.lifewire.com/what-is-a-...vate IP address is,a home or business network.

Thanks a lot guys! Much appreciated
