Hey, so I have had this issue for a while now and the problem is that I have an internet that is I think 800/200 Mbps and sometimes it just randomly drops to 100/100 Mbps for no reason whatsoever. I am usually downloading for like a day or two normally and then suddenly my download and upload speed are stuck at around 100/100 Mbps (I check it in my Ethernet status and also in the network status in windows settings, both show 100 Mbps speed) and even when I force the speed to bude 1 Gbps full duplex, it is still stuck at 100/100 Mbps.

In order to fix the speed back to the original speed again, I have to disconnect my ethernet cable for like a minute and connect it again, I also usually restart my PC after doing that and it's back again to normal speed.



First of all I want to say, my ethernet cable supports up to 1 Gbps speed, I am actually downloading at the moment I am making this post Stellar Blade, I download around 103 MB/s with peak being 103.4 MB/s, my disk usage is at the moment at around 104 MB/s so my cable is fine.

Second of all, I don't think there could be anything wrong with the cable because whenever I disconnect it and connect it again, it starts working fine.

Third of all, I have looked up some videos and also some reddit comments and usually people just say that all they did was set the speed to 1 Gbps full duplex and it worked or that the cable is possibly damaged (which I don't believe is true in my case because it works fine when I unplug it and plug it back in again). I have also tried to update my drivers, but they are up to date.

I can't really figure out what is going on, I have a new internet provider, but it's not the problem either because this all started happening like a month ago and I have a new internet provider since 18.6.2025 (which was 3 days ago).

Do you have any idea what might be going on? is there something in my PC that might possibly limit it whenever this and that happens?
