W10 22H2 Drops Internet Download Speed Dramatically

Topic

New Reply

I have two self built computers that have been running W10 21H2 without problems for months.  Yesterday I updated both to ver  22H2.  One updated without problems and my internet speed is what it has always been.  On the other, the install apparently went fine, but now the internet speed has dropped by 90%.  Searching on the net has indicated that this is an apparent problems for a significant number of people although none of the things suggested as a fix seem to work.  Since one computer is fine and the other problematic, I know that the internet itself is not the problem.  I’ve updated the software for the controller and that does not seem to help either.

Any suggestions as to things that might have worked for others would be appreciated.

What’s the brand of the Internet driver, have you disabled such items as rss and toe?

The Internet Driver is Realtek Gaming GbE Family Controller. I see RSS is enabled but note nothing in the way of toe if I understand it correctly.  FYI the controller in the unit that is NOT having any problems is an Intel Ethernet Connection (7) 1219-V

Try disabling IPV6 (only on the trouble computer) and then full reboot router and all computers.

That’s what worked for me and I haven’t “yet” run into any sites I can’t access/view using IPV4.

Sadly, disabling IPV6 on the problem computer, rebooting both computers the router did not have a positive impact on the speed, but thanks for the suggestion.

It is interesting you saying the speed has dropped by 90%. Have you checked the link speed on that adapter?
From PowerShell you can run the following command to quickly check: Get-NetAdapter | select interfaceDescription, name, status, linkSpeed

It’s somewhat of a longshot but a lower link speed would align with your reduction in internet speed. Some Realtek Ethernet adapters had an issue previously where the adapter would get stuck at a 100Mbps link even when connected to a gigabit switch port.
Generally the issue was fixed by installing the latest driver from the motherboard manufacturer or the Realtek website (not from Windows update) but it appears you have updated the driver already.

Some were able to workaround the link speed issue by changing the adapter setting for speed and duplex from Auto Negotiate to 1.0 Gbps full duplex.

When tested, the link speed was determined to be 1000/1000Mbps

That cannot be correct. No software can transfer at wire speed because there is always some overhead.
You must run a test that copies software between machines to find out the true speed.

You are correct, I didn’t realize that what I was doing was internal to one machine. However when I try to use LAN Speed Test to check one PC to the other that doesn’t work at all even though I know that I have the right IP numbers for each NIC.  When I check internet speed with only one computer connected at a time and directly to the modem, one runs at 50 and the other now has degraded to about 2. Which brings me back to the original question I asked:  Why would updating from W10 21H2 to 22H2 have no detrimental effect on one computer and make it essentially impossible to get a working download speed on the other , especially since it was built less than a year ago so it doe not have a lot of aging parts!!  I’m wondering if anyone else has had this kind of problems after updating to 22H2 and if so was there a solution other than possibly updating the software on the NIC which is on the motherboard, which I have already done with no improvement in speed on the problem plagued PC.

 

Thanks in advance for any further suggestions from the group.

Check the speed between your computers to see if it’s the network controller or something else.

You can use the built-in robocopy (see this post) to do the speed test.

You need to test machine to machine to eliminate the network card, then you can concentrate on the internet speed.

You are correct, I didn’t realize that what I was doing was internal to one machine. I have now used LAN Speed Test to check speeds.  Computer G checking upload and download from J shows download of 688 and upload of 349.  However, J cannot do anything from G and the error message suggests problems with permissions.

I should mention that since the time that I built J, it has never been able to view files on G even though G can easily see shared files on J.  But both G and J show as computers on the network when the network is viewed from either machine.  The kicker is that while G can be seen from J, when you try to look at files an error message of “Windows cannot access G” appears. One would think that data should go both ways. So far, searching on the web and talking with friends with more network experience than I have, has not been able to provide any suggestions that solved the problem so that is why I am reaching out to AskWoody with so many more folks that are computer savvy.

While I ultimately want to solve the networking problem, my most important task is to get the internet speed back to normal on J.  Until I updated both machines to 22H2 they both had download speeds of about 50Mbps.  G has maintained that speed but J has dropped to about 2 Mbps (even if hooked directly to the modem and not going thru any switches).

Thanks for sticking with me on this.

This is most likely to be a double NAT issue within your network.  You’ll find that Remote Desktop Client (RDC) will have the same weird one-way thing.   You can battle with it for ages and some things will work, others, no, even though it looks like you’ve done everything.

Others have mentioned the IPV6 situation.  You need to turn this off on every single machine and network interface within your house that goes through the router to the internet.

You need to check that only one router is using NAT – it could be that you have repeaters, say, through the house, that are acting like servers using NAT.

There’s a setting called LM Browser (local master browser) that you may come across in windows’ networks – make sure that only one machine has this ticked.

You mentioned permissions too…..  I had a fix for all of this stuff back in win10 2004, but it no longer works for me.  However, have a go and it may give you some pointers, which I wrote about here.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

However, it doesn’t address your internet speed problem, but it may be tied up in it.

Have you tried a speed test with just the one problem machine running in your whole network;  phones, tablets, doorbells, smart lamps and the rest all turned off and the whole network thing starting from a cold boot after clearing DNS caches?  Make sure to start the modem-router first and once it’s up & running steadily only then fire up your windows machine.

Then do the speed test.

By doing things like this it gives all of the series of electronic components time to settle down in a calm and steady manner, instead of firing up the whole network and DHCP addresses being rapidly pinged around your network.

It makes it easier to find a fault without all of the other issues clouding things….  It could be something simple like a new network card e.g. at work, the IT old hands never relied on mainboard ethernet but always installed an Intel card when they set up a new machine… This fixed my machine from weird behavior that I’d experienced for about a month until I mentioned it to the guys.  It was a speed and dropout thing that got worse through a few hours and was fixed with a quick reboot.  Obviously this was a pain for me as a developer across the 300 miles of our network!  I had been blaming the 300 miles of network and I was wrong!!!  New Intel card in a PCI slot and it all worked perfectly.

Currently, in my new big box, I don’t use the mainboard ethernet and have installed a dual output NIC in a small PCIe slot.  Lesson learned!

Double NAT will not exist within your network if all machines are connected to a single router.
Why you would have any other configuration would be a mystery. 🙂

After reading your post and basically coming to the end of possibilities from other posts, I decided it might be worth using a separate NIC card rather than the one built into the motherboard.  In searching the net I found that others have solved or at least helped their situations with a separate NIC card. Surprisingly my download speeds using  Speedtest.net now show speeds of 50mbps with and without VPN, just like it used to, using a $15 EDUP PCIe Gigabit Network adapter.

Now it’s on to the problem of Computer G being able to see J and download files from it, but J  being able to see G in File explorer, but not being able to see any shared files on it and getting an error that Windows  cannot access G.

Thanks for you suggestions.   Gary

This suggests your network card settings are corrupt because the issue only manifests under some situations. Given you have a working solution for very little money, I’d consider it solved and make an image backup of the working system.

cheers, Paul

I assume you have tested with different browsers?

I would make an image backup and then re-install Windows using the over the top method.

I finally got an opportunity to try a reinstall of the operating system using the over the top method. Sadly that has not changed anything i.e. the download speed with chrome is still 6 Mbps and computer J still cannot see files on G.

Now I did try briefly, as you suggested, to connect to the net via Edge and the downlead speed did increase to 25 Mbps and 42 Mbps on two tries, which I don’t quite understand as I thought Edge was based on Chrome.

Any other thoughts would be appreciated.

ATB, Gary

Now install Firefox and test speed with that.
Then uninstall FF and Chrome and test with Edge.

cheers, Paul

p.s. Edge is based on Chrome but the code is separate.

If your desktop machine(s) have wifi capability, test your download speeds on wifi. If still slow, test the wifi again using a hotspot from your phone.

Desktop Asus TUF X299 Mark 1, CPU: Intel Core i7-7820X Skylake-X 8-Core 3.6 GHz, RAM: 32GB, GPU: Nvidia GTX 1050 Ti 4GB. Display: Four 27" 1080p screens 2 over 2 quad.

I was able to locate a Cudy wi-fi USB 3.0 adapter that I had forgotten about.  Using it gives the same results for Chrome, Edge and Firefox, with Chrome still being less than 10.

The next thing that I tried was to completely uninstall Chrome from the computer, reboot and then do a clean install hoping that might offer  better results, but no, still the same 10 download speed with Chrome.

Since two of the three browsers I’ve tried have decent speeds, I suspect it is not the built-in NIC on my motherboard, but rather something with Chrome on this particular machine as Chrome on my other machine works fine at my normal download speeds and both, as I have said earlier have the latest updates available on W-10.

Any other suggestions from the various folks trying to help would be most appreciated and thanks to all how have offered possible solutions so far.

I am now able to work on this problem again.  I tested with Edge and got a download speed of 25 with my VPN on and 54 with it off.

Using Firefox I got 50 with my VPN and 53 with it off.

Chrome still shows only 10 even without the VPN.

I’m wondering if I perhaps should totally uninstall Chrome, reboot the computer and then reinstall chrome and check speeds again in case there is something lurking that I haven’t found that messes things up on the problem computer

Per the suggestion from Tech Tango, my desktop machines are hard wired to the router and I don’t have a wi-fi card installed.

Have you tried updating the Realtek Gbe driver?
https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software
The most recent for W10 seems to be 23rd May 2023 weighing in at 4mb, I prefer to disassemble the package and install via device manager over any installers when it comes to drivers YMMV

Something which I noticed over on borncity that may be of interest:

I have updated the driver per your suggestion and that had no impact on improving the download speed with Chrome.

Reply | Quote

I have little understanding of Chrome, and of user profiles / customizations.

With Firefox, one may uninstall/install FF without affecting a user’s Profile. A common debugging process in FF is for one to create a new (for testing) Profile to see if there is any change in behavior.

Did the Chrome uninstall and reinstall include a creation of a/the Chrome user? Or is the ‘resident’ user definition essentially unchanged?

Reply | Quote

I am not sure what you meant by:  Did the Chrome uninstall and reinstall include a creation of a/the Chrome user? Or is the ‘resident’ user definition essentially unchanged?

After I reinstalled Chrome I just used the credentials I always use to sign into chrome for either machine and after Chrome finished doing it’s thing chrome looked identical on both machines.  BUT, the download speed remained ultra slow on the problem computer.

I’m sorry: In Firefox, a Profile is that ‘FF User-ID’ the which is currently in use.
What I’m suggesting is that you (if necessary, Close/Exit your current Chrome ‘userid’, and) create a new/different credentials/profile/’userid’.

Why? We need to confirm that the problem is not some quarrel between Windows and your Chrome ‘user profile’ on this machine.

” to sign into chrome for either machine ”
I understand this to mean that the credentials/Profiles on both machines are intended/supposed to-be duplicate/identical.

In Firefox, one may delete and replace the application itself freely without disturbing existing Profiles. Are you having to completely re-define your Chrome user credentials after you’ve re-installed Chrome?

Have you tested with other browsers? MS Edge, Firefox etc.

Yes, I mentioned earlier on this long and getting longer thread that I tried both Edge and Firefox and both had speeds more like what I used to get with the problem computer prior to 22H2 install. Using wi-fi instead of my typical hard wire connection did not make any difference either.

I’m beginning to wonder if my NIC on the motherboard or the BIOS itself might enter into any of this.  Both of the machines have Gigabyte motherboards, but they are different models and research has show that there have been two BIOS updates since I built the problem computer.  Someone else commented that stand alone NICs are often more reliable than those on a motherboard, but I personally have not had any experience with that phenomenon.

Thanks to all again and still hoping to find the magic bullet that brings all back to normal!!

Have you tried running the windows networking troubleshooter and if so, what did it tell you?

Also, have you tried mapping by IP address as opposed to computer name?

Windows networking trouble shooter provides no information at all as it tells nothing after running it times over the last few months.

I have not tried mapping by IP address and will have to do some searching to see how to potentially do that.  If you have any quick suggestions I’m certainly open to them.

Thanks.

Hi
To save looking up the IP address of your machines each time, you need to fix them to an IP.
You do this either (or both) from the network card settings or from within your router by assigning an IP address to the computer’s MAC address.
Suppose you have two machines, alpha and beta.

Typically in  a  home network you give them IP addresses of 192.168.1.101 and 192.168.1.102 (say) respectively.  Most commercial routers default to either 192.168.0.1 or 192.168.1.1 as their gateway addresses…. These are private address ranges for networks outside of the internet.  Occasionally you’ll see a router using the 10.0.0.0 range.

In Explorer you’d connect to Beta from Alpha by typing either
\\beta or \\192.168.1.102
I’m guessing that \\beta isn’t working, but trying \\192.168.1.102 should work

This should work for RDC as well.

Similarly to connect to alpha from beta you’d type \\alpha or \\192.168.1.101

You can map the whole machine or just a certain shared folder or drive this way and give them a drive letter, but it’s not necessary . Thus \\alpha\my folder or \\192.168.1.101\my folder

Sometimes a trailing slash is needed.

I have been away from this thread for a while, can now report that all is well again.  The speed issues somehow resolved themselves, but the networking problem between two computers has been a dog.  It now seems to be resolved after reading an AskLeo article and going thru the steps he outlined which essentially involved adding a new account to each computer which each had the same username and password.  I ultimately made them both Administrator accounts but that might not have been necessary.  It turned out that as soon as I signed on to my wife’s computer with the new account each computer could see the other and any drives or folders that I had set to be shared were now accessible and could be worked on from either machine. Apparently hers  had the problem somewhere and mine did not. The reference to the article that helped me is:

Forgive me if any of these ideas were already mentioned and/or tried above.

I’m not a network expert by any means, so take that into consideration with the following:

(1)  upgrading our home lab to 2.5GbE was a great learning experience:  as a general rule, we found Aquantia controllers were much more reliable than Realtek controllers, in our experience

(2) Sabrent USB 3.0 dongles have been the most reliable, probably because the USB 3.0 standard is very stable at 5 Gbps, using the 8b/10b “legacy frame”;  you might consider purchasing a new model, just to keep on hand for testing and comparison purposes;

(3) if your Gigabyte motherboards have at least one legacy PCI slot, you should be able to experiment with a good ol’ Intel Gigabit NIC for that PCI slot at used prices e.g. at eBay;  ATA-133 turns out to be almost exactly 1 Gbps raw speed (32 bits @ 33MHz / 8)

(4)  I mentioned (3) because a fresh Windows OS install typically comes with a working driver for those ol’ Intel Gigabit PCI NICs

(5)  from the latest speed tests you are reporting, the slowdown appears to be unique to Chrome:  as such, have you contacted Chrome Tech Support to see if they have already encountered this same problem with W10 22H2?  try starting some email correspondence

(6)  the slowdown began when you updated Windows 10 to 22H2:  that strongly suggests a change in some internal OS setting, NOT in your hardware and network topology;  as such, I would submit a Trouble Ticket to Microsoft too.

my 2 cents

Good luck!

Susan,

What do you think of this idea?

A 2.5GbE USB 3.0 dongle like the Sabrent NT-S25G should install easily in one of his integrated USB 3.0 ports.

Here’s the Newegg link;  it’s probably cheaper elsewhere:

https://www.newegg.com/p/0XM-070Z-000H8

There is also a 5.0GbE model that is more expensive:

https://www.amazon.com/Sabrent-5-Gigabit-Ethernet-Adapter-NT-SS5G/dp/B08977K9D2

My theory:  the USB pathway to the OS kernel should bypass some of the OS code required to support the PCIe bus and/or integrated 1G NICs.

Best case:  the speed returns to normal

Worst case:  this trial-and-error can be shared by escalating this problem with Chrome’s Tech Support staff.

FYI:  I’ve come to prefer Marvell / Aquantia controllers, mainly because they work so well and they also support multiple configuration options.

Another neat feature is the driver installation procedure:  when this dongle is connected the first time, it emulates an OS drive letter in the file system, and the User merely needs to click on the install file (if it does not install itself automatically).
