Just a rerport about my internet connection

Use another computer to see if the same problems would happen to a different computer.

If a different computer has the same problem, then your router is faulty.

If no extra computer, download and burn a Linux Live USB and test from it

sounds like your computer is switching from wired to wifi, bu the wifi isn't working, can you just shut off the wifi?

My guess: it's your router.

A lot missing here. Like what wifi? Typically this would be a home wireless internet router that has ethernet ports and wifi, so the wifi would be to the same cable connection. An ethernet connection to a router is typically the most reliable, trouble free and definitely the fastest. Also, what about other devices, eg cell phone? Does that stay connected and work on wifi or have problems too? Anything else connected to the router? If so, try disconnecting that? Reseat, replace ethernet cable? Move it to another port? Could do a factory reset on the router. After that, I would probably start with replacing the router too. Who owns the router, sometimes they are provided by the cable company and you can get it replaced for free?

I would say your symptoms haven't really changed, it's been the same problem all along. Both networking devices dying at once, is mere coincidence.

It seems your PCH (Southbridge) is a potential root locus, but I can't be 100% sure of that.

The nice thing about modern processors, is the RAM sticks are mounted on the side of the CPU. This makes it possible for other parts of the machine to break, and the machine can kinda continue to function.

You might ask "well, how could my storage work?". Some of the newer designs, the CPU is a SOC, and it has a minimal set of I/O off the CPU as well. Maybe a couple SATA ports and a USB3 or so.

But the networking, it needs a bus connection like PCI Express, and the lanes for that trace to the DMI.

CPU --- dual channel memory | | DMI (about 4 PCI Express lanes worth) | PCH --- PCIe --- Wifi chip (PCIe x1 lanes worth) | --- LAN chip (PCIe x1 lanes worth) SATA

Yours probably isn't new enough to be a SOC, and SOC would be more likely to be an AMD design. This leaves the question, if some bus connection on the PCH is dropping out, why isn't the lack of SATA storage blowing your machine out of the water ? Windows hates it, when it cannot write to a disk! It should have been "crash-ola".

It's pretty hard to understand what "thing" is dropping out. There are *lots* of low voltage DC supplies in there, at least five voltages on the PCH, but again, if any of them affected the SATA, you could be quite dead as a result.

The thing about modern silicon, is core silicon does not fail. It's the pad ring, and power supplies, that have the highest incidence of failure. For example, I had a SATA port blow out on the X48 machine, and that seemed to be traceable (at a guess), to a disk drive that was exceeding the allowed common mode voltage on its SATA port. And that may have blown the motherboard interface to that SATA. For a short time, I operated that hard drive, via an Asmedia plugin SATA card, and it did not suffer a similar fate. I needed to do that, to clone the drive to a new HDD.

The puzzler then, is why is your storage working ? Why that particular pile of s*it blinking out ?

My Intel ICH5 board blew out.

My Intel X48 board blew out.

Which one is next...

Maybe this is why the newest motherboard is AMD.

He's got too much Device Manager damage.

If the router was bad, the Device Manager would remain in pristine condition the entire time. Just the "globe" symbol in the Task Bar, would be graphic evidence of networking trouble.

Windows 10 tends to automatically load drivers, and pave the Device Manager until it is "pretty". Unlike earlier Windows OSes, where you did the paving work your own self, with the driver CD.

Perhaps the drivers for his network adapters have become corrupted? Would it help if he uninstalled and then re-installed those drivers after first seeing if there are any updates to the drivers he has been using?

On WinXP, there was setupapi.log or such, and it contained excellent evidence of trouble. If the system was reinstalling or reinstantiating hardware, you could have log entries about it. Each time hardware was fiddled, there would be a dated entry with the details. And as the user, if you said to yourself "I wasn't installing drivers on that day", then you'd start looking for a culprit.

This changed on later OSes, and I could not see the same quality of log info after that.

If the LAN chip was being reinstantiated, the instance number would changed.

For example, my RealTek LAN right now is named

Ethernet adapter Ethernet 3

Which means the adapter may have been uninstalled and reinstalled a couple times since the OS was first installed (about two years perhaps). Some people have higher numbers than 3, which is a hint that a much more frequent event is happening which causes the driver to be reinstalled.

There could be something wrong with the hardware, but I don't want to over-pronounce on the thing. I can't be sure it's some DC regulator on the motherboard doing this. It could be a malware for example (as unlikely as that would be). Malware writers, the good ones, leave no trace of their craft. But it is equally hard to understand how the software could be doing this all on its own.

And if the RAM was bad (something I have run into), what are the odds that the bad RAM locations are only in low RAM ? I had a problem where a Windows machine, would "drop dead" after roughly 15GB of disk reads, and that was bad RAM in the buffer area used by disk operation. Memtest could not even tell me which stick was bad, so I had to replace all four sticks.

a) For wireless, it's a Qualcomm driver issue. You would need to use something like Snappy Driver Installer Origin (freeware) and let it find the absolute latest driver for your device then install it.

b) For cable, if it's become unstable, there is a good chance that you have corruption in your system files. You'll need to run the Command Prompt as an administrator (right-click the program, Administrator), then type in the command "sfc /scannow" (without the quotes). Once that finds the first set of corruption and fixes it, run "DISM /Online /Cleanup-Image /ScanHealth" to determine whether there is greater corruption in the system files. If it finds problems, run the same command but replace /ScanHealth with /RestoreHealth.

Let me know.

Well, the wifi works well for 2 or 3 or more days at a time, but your suggestion was the simplest so I turned it off a day ago.

It will take several days to know if this improves the cable connection.

I wonder how long it will take me to rmemeber to turn the wifi back on next time I take the laptop out of the house. I'm sure I'll forget. :-)

If it works fon'r wory about 3 and 4. Sounds likme perhaps something updated and blew out your drivers for your wifi and network interface. Disabling and re-enabling re-installed and reset the drivers (my best guess after a few decades in the business)

Well, it took only a day. The cable connection failed a bit ago (and I got the icon of the world, with a few lines of lat and longitude.)

I turned wifi back on, and just like before, it still didn't work until I unplugged the cable. Surprising. The cable works even when wifi is enabled, but not the reverse.

So not a problem anymore.

I appreciate the other suggestions, but they would be too much effort for too little likely gain, and the subject line did say "Just a report...", so I'm not going to try them. Thanks anyhow.

Disabling/re-enabling drivers, and searching for an updated driver is a very fast and easy task with Win10. Just because you've never tried it doesn't mean it's complicated or will take a long time.

In your search box on the windows task bar, write the words: device manger

When it opens, scroll down the list of devices until you see: network adapters

Highlight the adapter you want to work with a single left click of the mouse. When highlighted, right click on that specific adapter. From there, I would first disable and after a minute re-enable the driver. If that didn't solve the problem, the next time's I'd click on update driver and then select the automatically search for an updated one. If the search finds one, install it.

Total time of fussing via the device manager, probably less than 2 minutes. Nothing ventured, nothing gained.

Device Manager is also available by right-click Start icon and is in the menu there. No typing needed. It's about fifth item down, out of seventeen items.

With network hardware, you can run two of them at the same time.

You don't really have to be beating your network controllers over the head constantly with a mallet :-) [ Even though the Airplane Mode key on the laptop keyboard, can be used to turn off the Wifi RF signal. That's a way to do it, for all the RF outputs. ]

How the hardware picks a path, is influenced by the "metric" or weight applied to each hardware type. You can set a kind of "preference", like if the Ethernet is set to 1000 and the Wifi at 5, as soon as the Ethernet is connected, it takes over. Very little traffic then travels over the Wifi.

If you use the default, and both are set to 5, then some of your traffic goes over the Ethernet, and some goes over the Wifi. And the traffic must be routed, so the sequence of packets is preserved.

There is also Link Aggregation, which is typically used with a pair of identical network setups and no router in the path. You can have two Ethernet cards in each PC, and connect to a pair of Ethernet cards in a second PC. That gives "double the bandwidth". At one time, before there was a standard, some manufacturers provided a proprietary solution for controlling packet sequencing (you might use their Teaming driver).

Computers are full of tricks, that's for sure.

When I saaid too much effort, I was combining all the suggestions together, not giving your priority, because after all, what do I know about what will work and what won't. I might well have to do them all before I find one that works, and maybe I still won't find one.

That's what I did in my first post here. I guess it was too long and people didn't read the whole thing. Sorry.

But since y ou went to the trouble to post again, I did this and it said I already had the best driver for wireless and for wired, but when I looked anyhow, nmayyyyybe I found one in the Optional updates. It's called Realtek - net 5/5/2015 12:00AM 10.1.505.2015

Now is this a replacement for Realtek PCIe GbE Family Controller? 4/10/2015 9.1.410.2015

It's a month newer and gen 10 instead of 9, but is it meant to be a replacement? If so, why not the same name?

Already I've spend more time than I wanted.

No. More than that. :-)

Okay. Not worrying abou things is something I'm good at.

Thanks and thanks all.
