Ethernet Issue Windows 11

[skayqz]

Hi, like a week ago i put my old 15 meters flat cable after moving it a little bit into my pc, and it just refused to work, ordered a new ethernet cable, and it does the exact same thing, BUT if i plug the new ethernet cable (i got rid of the old one) into my LG TV, it works with no problem.

Motherboard flashes the orange light like 5 times every like 1 minute tho...

What do i do?

need to know more about system, or at least what the motherboard is.

generally speaking, a flashing amber light at regular intervals indicates a connection problem.

What does Windows report?

 

FYI, flat cables are much more susceptible broken wires.

Lenovo Legion y520 prebuilt but upgraded

Specs:

Cpu : AMD Ryzen 7 5700x
Graphics Card : Inno3d GTX 1080 8GB GDDR5X

Ram : 1x g-skill 16gb ddr4 and 2x hyper fury 8gb ddr4, both 3200mhz.
Mobo : Asus Prime B450M-A II
550W MSI MAG A550BN Bronze

 

And also please tell me what you mean by what does windows report.

 

Edit: A funnier thing is that, i plugged it into a linux based tv receiver, and it worked like a charm, im contemplating to get a live boot usb drive to try it out on my pc but with linux, like fedora or something.

so your running your system slow for a reason?.. if you don't get matching pairs it will not use dual lanes memory speeds. are you sure it runs 3200mhz? . 

 

and look for new drivers for your nic.. mine are updated all the time.. and it's a 7yo mainboard..

@skayqz

Windows report means like in Task manager and Device manager. What does task manager show for networking and does device manager show the ethernet adapter and if it's working. 

 

Did you plug the pc into the linux receiver or are you just talking about the cable?

Could just be a driver issue. Check Device manager.

Was there tension on the ethernet port from the cable?

my gut guess is that the ethernet port may be damaged and only makes connection when just right. Try moving the cable near the port a little and see if it effects the connection.

Broken solder points can often cause intermittent problems.

Bro your gut should put a lottery ticket, you are right lmao, when i shake my pc lan port for a while the lights stop for a bit

If it happens again, just run this in PowerShell to get a physical and IP status of your Ethernet adapter.
 

Get-NetAdapter | Where-Object { $_.Name -like "*Ethernet*" } | ForEach-Object { $adapter = $_; $ipAddresses = Get-NetIPAddress -InterfaceIndex $adapter.IfIndex -AddressFamily IPv4 -ErrorAction SilentlyContinue; [PSCustomObject]@{ Name = $adapter.Name; Status = $adapter.Status; Hardware = $adapter.HardwareInterface; IPv4Address = If ($ipAddresses) { $ipAddresses.IPAddress -join ', ' } Else { "N/A or Disconnected" } } }

Also, your adapter is a Reaktek RTL8111H. Update the drivers for it below.

Choose "Win11 Auto Installation Program (NetAdapterCx) - Not Support Power Saving" for two reasons.

1. NetAdapterCX is the new Windows driver framework for adapters
2. Some routers or switches don't like adapters that conserve power; it breaks layer 1 connectivity.

well after over 30 years you get a feeling for this stuff.

So looks as if your gonna have to RMA the board or buy a ethernet card.

that sucks

actually it was this; "15 meters flat cable after moving it a little bit into my pc" clued me in that there may have been tension pulling on/stressing the port.

Idk if over time im gonna have a real problem, but for now everything is good, also by that i meant that i was moving my old ethernet cable from one room to another because i was just renovating my interiors and stuff, anywho thx lol

Its nothing too serious enough for me to say that i need to do something to fix it, for now its all right as if i only move it it disconnects which i dont do that much
