Internet cutting out intermittently, at random intervals, and random length.

So as the title says. My internet has an issue where it will cut out at completely random times, from anywhere between a few seconds, to up to 10 minutes. It can happen zero times per day, or up to like, 4-5. There is no real link between the issue and when it occurs, it just feels completely random. I've had it happen in the morning, noon, afternoon, evening, and the middle of the night (I have a pretty odd sleep pattern, so I've seen it happen basically any time.)

When the problem occurs, the LED lights on my network adapter shuts down, and I can almost feel how much its struggling to get back to working.This has been an ongoing problem for many, many months now, and I have tried, what I feel, is every single trick in the book. I am gonna try and list what I have done so far, to root out some elements.

I have tried

3 Different cables
2 Differen't ISPs
2 Different modems / routers
Direct connection to said modems
Complete Windows re-set.
Various windows 10 settings regarding the internet (Energy save for example.)
Various settings in our modem / router
2 Different network cards

And basically every single common "Fix," I could find through google and youtube.

At this point I feel like I have tried absolutely everything, and am now turning to forums and communities for more ideas. I've also got a small log of most recent failure, which shows when it started and how long the cut-outs last.

When it comes to the internet icon on my windows taskbar, it will often just spasm between "Yellow" and "Red." And sometimes it'll just go full circle.

I've been trying to run diagnostics as much as possible as well. Either it just says the cable isn't plugged / broken, or it will say the default gateway is not available, after which it'll reset the network adapter. I've tried running with automatic DNS and Google's DNS, both with the same results.

Are you using a modem/router or separate modem and router?

In either case, have you checked the wall outlets providing power to the device(s)?

Could be just a loose electrical connection inside the power outlet being used or somewhere else in the circuit serving the outlet(s).

Any other signs of electrical problems within your residence? Flickering lights, breakers tripping...?
 
Might want to check your outside cables as well, esp. w/ cable internet. Those cables don't last forever, esp. in bad weather, and can be the cause of intermittent service. Had this problem myself one time in PA. Cable guy came out and replaced all the cabling leading from the street to the house, no charge (they're supposed to change it anyway at scheduled intervals). He showed me the old cable, and it looked pretty bad. Prior to that, I had a similar problem in FL and it turned out to be a construction company on my neighbors front lawn, near where the cable lines were buried (not sure why the cable company did this, but it happened prior to my purchasing the house), who ended up cutting through them!

So when you've exhausted just about everything else inside, you need to consider the outside as well. It might even be lines elsewhere in your neighborhood, and affecting our ppl as well. Maybe a tree branch has extended to the point it's scraping the lines and no one is even aware of it until someone complains!

I am not sure about the modem / router combination stuff. I think we just have one modem now. As for cables outside of our apartment. When we switched from one ISP to the other, we also changed from, I think phone lines or something. To a connection through TV cables. Seeing as the issue stayed the same, it's probably safe to say that, that isn't the issue.

I had an episode again just now, and using the diagnostic repair tool actually made it work again. It has to reset the Ethernet adapter, with the "Default gateway not available" issue being the only problem listed.

With respect to "modem/router":

Users have two options: 1) A modem with one Ethernet port connecting to the WAN port of a router. And the router's LAN ports providing wired connectivity to network devices. Many routers now include wireless as well.

Then you can have a combination modem/router with the device doing double duty: acts as both a modem and router, Newer modem routers can include wireless functionality as well.

Look at the device(s) on your network. Post the make, model, and version numbers. That information should be on the device labels.

What may be necessary is a firmware update to one of those devices. Firmware is the built-in code to tell the device how to do its job. If the firmware is buggy then the device will fail with the end result being problems of one sort or another.

My thought is that there is a physical issue. AKA "bad connection" somewhere. However, I have also learned not to exclude anything until I can prove that that is not the problem.

What diagnostic repair tool are you using?

Reading back: have you downloaded and reinstalled the driver's for your network adapter card via the manufacturer's website?

I have no reinstalled the drivers for the newer network adapter, I did try to do it for the original one though, to no avail. I will be happy to try and do it for the new one and see if it helps, however that will have to be tomorrow, as I am heading to bed soon.

Also, we are using a Gigabit modem called "Sagem Fast 3890," so no router or anything in between. And since I have tried connecting directly into the modem from my PC, I am pretty sure its not a fault in wiring of our walls.

I'm gonna try re-installing the Adapter software tomorrow, and then I'll see if that helps.
