Bandwidth monopolization

Question

Hello,
I've been suspecting my brother of monopolizing the connection for a while now because it was impossible for me to watch a video on YouTube at 720p. Yesterday, when he turned off his PC, I tried 1080p like I used to and it worked perfectly. I conclude that my brother has found a way to appropriate a large percentage of the bandwidth, but I don't know how.

I checked the router settings and his machine address remains fixed at 192.168.1.1. Is this address "priority"?

Secondly, in the NAT/PAT settings, he deleted my rules for Minecraft and set up rules for "Teredo." I looked it up online, and it's a means of simulating an IPv6.

Otherwise, maybe some sneaky software is responsible for his trickery?

I would like to point out that when his PC is on, I download at less than 100kb/s, but when I'm alone, I’m at 1.1MB/s. Theoretically, if sharing was good, we should both be at 550kb/s, which would certainly be enough.

Anyway, if you have any ideas, thank you in advance :)

Best regards.

Configuration: Windows Seven | 4GB RAM | i5 750 | ATI 5850 msi

Hello, I've never responded to any forums before, but today I'm doing it because I'm sure I have the solution...

► Open cmd.exe (as administrator)
► Type: netsh interface tcp show global
► if it says "Auto-tuning level: None" then it means this is not the solution... but if it says restricted instead of none or normal, it means your brother is monopolizing the connection...
► Type: netsh interface tcp set global autotuning=normal
► it displays OK.

the connection is then set to normal and no priorities are given...

to monopolize it in turn, type: netsh interface tcp set global autotuning=restricted

here's the link to a video explaining it: https://www.youtube.com/watch?v=2IVU1HrZk7U&t=97s

there you go! hoping to have helped you... otherwise, send me an email and I will reply: ***@***

I don't have too many ideas at the moment, but you can always blacklist his address in the box to teach him respect.

Hi,
Our relationship is not on the best terms, which explains his behavior, but I'm not sure either that it's intentional. He trusts the forums that give tips so much that he doesn't realize it's affecting me, and he doesn't care.
Anyway, I'm willing to try this manipulation and see if my speed goes up, but I would like to know how he was able to prove it.

I could also do a little reset of the box to start everything from scratch (rules, etc.), then I could see if he tampered with the router or not.

Control Panel -> Network and Internet -> Network and Sharing Center -> Change adapter settings -> right-click on the network adapter -> Properties -> Configure -> Yes -> Advanced tab -> Select Speed & Duplex from the list -> Set the value to 10Mbps Full Duplex -> OK.

Problem solved

Then watch Oppa Gangnam Style on Youtube in 1080p and enjoy the bandwidth :D

Thank you very much cyril and me.rbib.

Hum screugneugneu.
After a few conclusive tests, the problem ultimately persists after 10 minutes :/
I have no issues with online games, but when it comes to YouTube or downloading, it's different.

I thought I saw that with the method above it affected a "proxy", I wonder if actually this method indirectly resolved the problem before it came back.

Hello, yesterday I asked my mother to take care of it, and she talked to my brother. He claimed he hadn't created the Teredo and Company rules on the box; he deleted them (there are still two rules for Hamachi). The problem persists. Once again, after going to bed, my speed was immense even for my mobile that is on WiFi; I was able to watch a playlist in 1080p.
In my opinion, he must have tampered with something on his PC or a software that's indirectly hogging all the bandwidth.

If anyone knows what he might have done, I would really appreciate it. :)

Thanks in advance.
