Intermittent ethernet disconnects

[xnoobftw]

Hi, my ethernet has been dropping really randomly (like there's no pattern) and at a very sparse rate (maybe once per 2 days)

 

What i've done

1) upgraded router to asus AX58U

2) bought an ethernet pcie card (realtek gigabit)

3) reformatted pc and reinstalled drivers

 

the wifi and other devices works fine during this period

 

I've asked here previously and it was mentioned that the cable is highly unlikely to cause this issue

The thing is im really only left with the cable as the issue

My best guess is that you're running into some sort of interference, which might require you to purchase shielded ethernet cables. I'm not all too familiar with this myself, but you might find this article to be helpful.

hmmm but the route from the router to my pc is through a trunk and inside that trunk its just the cable itself

 

im plugged directly into the router (not extended via wall RJ45 connection)

Based on my understanding, heat/cold/humidity, florescent lights, or even just poorly made cables can cause interference. I would give shielded cables a shot anyways, since it's probably not an issue with your hardware.

What is the Asus AX58U plugged in to? Exact make and model, please.

1. What is this trunk?
2. What category of ethernet is it?
3. Did you crimp this cable yourself or was it pre-crimped?
4. Have you tried a different pre-crimped cable altogether?

The ax58u is connected via WAN port to my ISP's Huawei Echolife HG8240h modem and it's fibre (500mbps up down)

 

Then it's connected to my computer's ethernet port(the onboard motherboard's killer gigabit and pcie ethernet card have the same issues so I doubt it's the port on my mobo)

 

1) the trunk is just some plastic trunk I got from a hardware store

2) cat 7 flat cable

3) precrimped 20m cable

4) nope

All the lights in my place are LED T.T I may just replace the cable if it comes down to it but its a pain

What's the purpose of this?

That Huawei ONT is an internet gateway. So it has its own router/NAT. Are you, therefore, running the AX58U in bridged/AP mode? See Advanced Settings > Administration > Operation Mode.

 

Also, I notice that the AX58U includes what looks like a lot of security features through AiProtection. While having a few of these active might not be a problem, having them all all takes a hit on the CPU at some point (especially things like IPS). Try temporarily turning AiProtection off to see if the problem persists. You can always use 3rd party DNS providers (e.g. CloudFlare, Quad9) for filtering.

The purpose of the trunk is for wife approval. I can't exactly have 20 meters of ethernet cable running through the house in a straight line

 

It's currently in router mode!!

 

As for the AI protection I'll give it a shot... The thing is only my wired connection is affected. The WiFi side of things are perfectly fine when my ethernet is hit

Gotcha!

You should really be running the AX58U in access point mode if you want to avoid double NAT and the slowdowns/hiccups associated with it. Then, disable AiMesh thereafter if it’s still activated.

OH!!! i tthink i managed to resolve the issue.

What i did was separated all the ethernet cables going into the router (i had them all cable tied previously together)

and scheduled a daily reboot @ 4am and that seem to fix the issue
