Internet breaks at random intervals and lengths.

Specs: Windows 10
So this is a problem I've had going for me for a couple of years, and after I've tried literally everything I could think of; different cables, directly connecting to the router, various settings in the network card, changing ISP, getting higher Down/upload, buying a new PCIe network card, I just can't figure out what else to do / try.

So what happens, is that my computer will have these "Episodes" Where the network will enter what I've come to call the dying state. Internet will stop working, the network icon will flash Yellow, and requires the diagnostic to be run, which will fix it by "Resetting Ethernet."

Problem is, when its particularly bad, this will keep going over and over for hours on end, where resetting will work for like, a couple of seconds / minutes, before it breaks again.

The usual message I get when this happen is that the "Default Gateway is not available." The problem persisted, although got a tiny bit better when I bought the new PCIe network card. Before, diagnostics couldn't even identify a problem. I've taken the liberty to make an Ipconfig /all, as this is often asked for when issues like this occur. Anyone's got an idea what my problem might be? Also, I am using a wired connection, not WiFi

Bit of a long shot... but have you checked the connections where your isp (internet service provider) service enters into your home? This point is often overlooked...

Also how olde is the router; and what make/model? Is it your own or one provided by the isp?

I have had problems with internet and finally tracked it back to the cable connector/joiner where the cable runs along the outside of the building before entering the house. Also slow connections were eventually found when the 5th or 6th person on the block complained and they finally found a problem component or connection on one of the poles on the block. Do not rule out a service provider problem, see if they are willing to come and test the connection into the house.

#1 - The modem I am using is a Sagemcom 3890, which were provided by my ISP. I am not entirely sure where to check the connection, when it enters the house, but I doubt that is the issue anyway. When we changed ISP, we also changed from I think phone cables to TV cables where the main source lies, and the problem persisted.

#2 - I have scanned for Malware, viruses and re-installed windows 10 completely, no change.

#5 - We've tried getting helping from our providers, but they see no issues whatsoever.

Has your isp actually been to your property and checked the signal where it enters the house? Many simply say "it's OK leaving us..." and leave it at that. Often one has to persist and keep at it until they actually arrive and check onsite.

Until you know for certain that incoming is stable, and at the level of service for which you're paying... you can't be sure where the problem lies.

Also is this the same modem in use for the whole period of connection problems? Not entirely unknown for a a router (be it phone wire service or cable/fibre) to go intermittent... Have you tried using another known to be OK router to see if problems persist?

"Default Gateway is not available." "could" well be because there is loss of incoming connection from the isp.... True there may be other reasons too...; including at the isp end of the line... But until you get the isp techies to come onsite and check what's incoming, and its stability etc; even to put a monitor across it for a while... you're really going in circles?

My brother a few years back had similar issues with his SKY service; took an age to get them to come onsite (actually it was BT who serviced SKY in those days) and confirm his termination point, where the service arrives in-house, was flakey... The put in a new installation in effect and he now has what he's paying for and stable too.

When I had similar issues too I leaned hard on SKY/BT. I had to get SKY to get BT to come on-site to confirm signal incoming - which the very able young BT techie soon confirmed as "variable and dubious" at my master socket to put it mildly; and set about renewing the system. BT techie discovered my phone-line incoming was rubbish from just after if emerged from the ground.... He installed a new (external) connection/junction box and from that ran a new phone line into the house and installed a new master socket. I mention the BT techie deliberately as, although very young (in his late teens!), he was very professional and actually cared about the doing the job properly. If he'd came to me for a job, based on what I saw chez-moi - I'd hire him; as his tech standards and workmanship were on a par with some of the best I've experienced in my various broadcast tech days..

Keep at the isp to get their finger out; after all you're paying for a service you may not be getting; in-spite of their "it's alright our end etc...".?

#9 - That network is my old one, which came with my motherboard. After many attempts at fixing the internet, we bought a new PCIe, with a different set of network drivers. I disabled the old one, being the gigabit network to see if it was interfering or causing issues, didn't really help, but it didn't make anything worse either. Knowing this, would you still like me to run the Snail?

#11 - Our ISP has not been to our area to check up on things personally. However, in an attempt to fix the issues, we changed ISP completely. Each ISP uses a completely different set of cables. The old ones used regular phone cables, I believe, and our new ISP runs through TV cables. With each ISP, we also had one different router. My computer is the only one in our apartment that is having issues. I could try and pester them to come make some actual check-ups, but given the circumstances I am afraid it won't really help.

I cannot rely on my neighbors, being prepared for me suddenly visiting with my stationary, set it up and see if its working or not, I wouldn't be able to tell.

Your computer seem to have hardware issues in my opinion. The on-board Network module is faulty. Now some other hardware start having intermittent problems or the faulty network module sometimes spring in to action again causing havoc. You can continue like this until it fails completely or just change your computer now....

Everything you've done/tried/said points to a bad network interface. I would try replacing the NIC with another, or even just a USB network interface as a test.

If you have, or know someone that has a working USB network interface, borrow it and run it for a couple days (saves you buying one). If the issues doesn't happen, you know for sure it was your NIC and need to replace yours.

I must have missed that Fingers I thought I read that he had replaced the onboard with a NIC and that was what was giving him the problem. I may have just misunderstood.

Well, if that's the case, I'd still be looking at hardware. It could be a problem with the motherboard or a conflict between two hardware devices. Have a look at your IRQ table during POST....is the NIC sharing the same IRQ as another device?

It could be the OS, a quick check for that would be to slap another HDD in (assuming you have a spare) and install Linux and test.

So my eyes glazed over read this thread, so someone tell me if this summary is wrong:
- The problem persists across multiple providers / routers.
- The problem persists across NICs.
- The problem persists across OS installs.
- The problem is not present on other devices.

Unless you're installing some sort of third party anti-malware, firewall, or virtualization software and not telling us, that only really leaves the Ethernet cable, or someone in the house messing with you. In which case, I'd suggest borrowing a USB WiFi adapter, and see if that works.

Razor’s comment (#30) triggers another angle of consideration here... and it’s a very.... long shot...

per chance there aren’t two devices on the network (be they games machines,iDevices or computers etc.) which happen to have the same ip address...? For this to happen it would require that the ip address on the problem computer or the other device has been manually set, rather than the dhcp dishing one out as is more the common practice/setup in soho networking?

Perhaps note assigned ip address for each device on the network - both for ethernet and wifi; then when the problem occurs... recheck what each active device has for its ip address.

Also each time you put the problem computer onto the network, make a careful check/note of what else is on the network at that time. When the problem re-occurs check again what is online; see if anything has been brought onto the network at that time, and note its ip address?

In effect look for a possoble ip conflict...

Sorry I have not responded during the last 2 days, it has been very hectic IRL, and has kept me quite busy. I've got a little update on the issues at hand, which might help enlighten the problem a bit further. So, my father learned that there's been a somewhat large update, somewhat recently for my built in network card, so keeping in spirits with trying pretty much everything, I gave it a shot.

I downloaded the newest driver from Intel, disabled my secondary PCIe Network card, uninstalled all the network drivers and then installed the newest version I had downloaded. Ever since, the random gateway issues have not been occurring, there is however, another issue with the main network card, which is that it will randomly, blatantly shut down for a good couple of seconds, before rebooting on its own.

Overall, it seems a lot more stable, and nowhere near as frequent when the issue arise, but it still a problem none the less, albeit different. The LED will simply turn off, my internet will disappear completely, and diagnostic will just tell me that there's no cable plugged in. This has only happened once since I got the new drivers, but used to be completely unreliable.

As previously mentioned as well, I have tried two different cables, which has never shown issues before, as well as directly connecting to the modem. We have however, ordered a completely new cable, to give that a shot as well.

Please check the tower for dust build up (vents, heat sinks, fans, etc.) because heat build up can cause weak components to become flaky.
Run HWMonitor and report the various temps at idle and after 20 minutes working. If high, that could be related. Also while you are at it, if the basic voltages (12V, 5V, 3.3V numbers are more than +/-5% out of the nominal then varying power levels can be the problem (bad power supply).

Had another incident where my network card simply shut off for a good few seconds, before turning back on. The LED Light went from green to Orange after it booted up again, and has remained orange since then, I do not know if that means anything. Internet has worked fine since though.

#36 - I was using a second NIC when I started this post, because the one built into the motherboard was faulty. I just switched back a few days ago cause there was a bigger driver update for it, and wanted to see if it would make a difference.

The frequency of failure has gone from sporadically going at it for up to 10 minutes of gateway issues over and over (Which were the second NIC) To the current (First NIC) shutting down once each day, for a good few seconds,before turning back on. After it shuts down and turns back on, the LED has turned from green to orange.

Your motherboard and most temps are normal but your CPU is running very hot at max.
Get a can of compressed air (never use a vacuum inside computer case) and blow out the CPU heat sink fins to remove dust from there and retest. I cannot see any relation of this to the NIC problem but maybe the CPU heat is causing something of a chain reaction or related to the thermal throttling of the CPU to cool itself. If it goes much higher I would expect the system to shut down abruptly.

When NIC ”turns itself off” as it were... is everything else ok as best you can tell, apart from cpu temperarure which is noted by others to be rather high?

I am wondering if Fingers (#33) is heading inthe right direction, in that you “may” have a dubious power supply; one that is failing with respect to at least voltage rail?

HWMonitor did not report primary voltages as I remember it doing in the past.
The BIOS set up screen will show the primary input voltages (12V, 5V, 3.3V), they all should fall within 5%+/- of those nominal values.
I guess the high CPU temps could be causing the NIC issues but more likely power supply. I wonder if the 12Volt rail is high enough it might also be causing some of the additional heat in the CPU.
Please try cleaning out the CPU heat sink (without removing it) by using the compressed air. If the cleaning does not solve the heat issue then you may need to remove the heat sink, remove the thermal compound, and replace if with the proper amount:
