VERY Slow Internet After Upgrade to 10

Hi jds63, I ran your command, it executed perfectly (except, if it matters, the final command, "reset ," (just a comma after the word reset), failed because "access is denied.") ... I rebooted, ran the speed test and still clocked out at 1.5 MBPS. So, alas, no fix.

I am connected to my CenturyLink modem which gives me full 18 MBPS, saving me from tearing out my hair, but I will continue to search for answers on how to get Windows 10 to connect to the TP-Link router connection at that same speed. In our two-story house, I need to be able to receive a fast router connection upstairs, and the CenturyLink modem signal won't reach up there.

O.k. try this

Right click the Start button, select (admin) command prompt, copy and paste this into the open command prompt and press enter let it finish, then close the command prompt

netsh int ip reset c:\resetlog.txt

Reboot the PC, try internet.

Scrap, what I said above. We posted at the same time.


I think you need do to factory reset your CenturyLink modem. Those modem whether it is comcast or any other cable company they are picky on how many wifi connection you can have. This mean you will need to reset each device that uses the wifi connection. I mean restore the wifi connection not reinstall each of the devices.

You might be onto something, consgle. I have the Linksys RE 4100W range extender. I just upgraded to Win 10 a few days ago, so I probably got the same update you mention. Help me understand: My range extender is feeding off my TP-Link router, so when I click on the connection I have named TPLINK, is my signal actually coming from the range extender, relayed from the TPLink router? I am going to unplug the range extender and see if I get full speed directly from the router. I'll post the result.

I am having the exact same problem as the person with Dell. The only difference is that I have a brand new HP Envy Computer that came with Windows 10. In addition, the first few months of owning the extender everything worked beautiful. My suspicion is that a recent Windows 10 update is not compatible with the extender.

I have followed all the exact same steps and also conclude that Windows 10.x and Linksys Extender RE6500 are not compatible. I have work to do and cannot go through this on a daily basis.

OK, thanks to consgle, we have narrowed this down! It's DEFINITELY an issue between the range extender and Windows 10. After unplugging my Linksys RE4100W range extender, I connected from PC to my TP-Link router and -- for the first time since upgrading to Win 10 -- I tested with a net speed above 1.5 MBPS. It clocked in at 13.5 MBPS! That's still less than the 18 MBPS I get on my laptop running Win 8.1, but it's good.

So ... any ideas on how we get Win 10 to play nice with the Linksys range extender? I need that to get the signal upstairs.

Here i was going to ask this next about your signal from WiFi to this Desktop or even about this router, but you swore there was nothing wrong with that part of it because of other systems working fine and what the manufacturer told you.

No comma here, this was all i meant to put in. Did you copy paste just this line below ?

netsh int ip reset c:\resetlog.txtc:\resetlog.txt

And this part just tells you were to put the log, it can be removed from the command c:\resetlog.txt

Because I have work to do and I am behind. I gave up went to BestBuy and purchased 100' Ethernet cable and now have this lovely cable running from the back bedroom to the front sitting room that serves as my office. The speedtest avg is 215 mps. BestBuy people suggested buying a AC modem, the cable company want to charge a setup fee and monthly fee to run a new LAN line. At this point my last investment is the 100' cable for $40. This is a brand new computer. Since I have had this new high powered computer, I have upgraded my internet service, bought an extender and paid an IT geek to help. No more. In addition, forget the wifi printer. Everytime the cable blinks and now that I am having trouble with wifi on the computer, I have gone back to USB connection for the printer. So much for getting into the 21st century.

By the way, has anyone tried the Apple airport extreme. As soon as my husband can find the old airport extreme, we will give it another go. We moved into this house a couple of years ago and the cable company did not seem to like us using an Apple product. So it is buried in a box. Before we go to the trouble, I would love to hear other thoughts. We are concerned that it may be too dated.

I agree, give up!! Range extenders are a bad 'answer' as they a reduce throughput by 50% as they can't receive and send at the same time.

I see you need a signal upstairs so the best solution is to run an ethernet cable up there and second best is to use a pair of powerline adapters in place of the ethernet cable. Then you can attach the gear upstairs via an ethernet cable, or attach a wireless router for wifi cover.

Something like the TP LInk TL-WR1043ND is good for the job and reasonably priced.

This is a better solution and will save all this grief you are having.

Ah, what I wouldn't give for 215 mbps! In my rural woods, 20 mbps is about the best they can deliver. But I will not give up!

We have 2 laptops, several mobiles, a printer and my desktop PC all on a wireless network in a two-story house. The modem/router setup must be downstairs (where my office and PC are). The laptops and mobiles wander all over the house, all use the printer, so wireless is almost a must.

And we are SO close to solving this! The facts as we know them:

1. With the Linksys range extender REMOVED, my Windows 10 PC gets nearly full internet speed.
2. Since everything else runs Windows 8.1 or mobile OS, they get full speed with or without the range extender.
3. But the range extender makes it possible for all devices to connect everywhere in the house, upstairs and downstairs, so we need that.
4. Since my Windows 10 desktop PC is anchored downstairs, close to the modem/router, it does not need the range extender signal, so I can connect instead to the modem.
5. Therefore, I could leave the range extender in and connect to that with all the other devices throughout the house.
6. The PC will connect to the modem signal that does not use the range extender.

In a perfect world (which it was BEFORE I upgraded to Windows 10), my PC and all devices would connect wirelessly to the router/range extender signal, all in one happy home network. I have to believe that's still possible without reverting back to Windows 8.1 on my PC.

I ordered a new range extender (actually, it's call a repeater, which may be something different) to see if Windows 10 plays better with that than it does with the Linksys extender.

I remain open to any suggestions and thankful for everybody's assistance.

Yes, I clipped and pasted the command exactly as-is.

FYI, I noticed something interesting today. When I run my speed tests with the Linksys range extender in place, the upload speed is about the full speed I pay for. It's only the download speed that sucks. And again, that only happens when the range extender is used. If I unplug it and connect wirelessly to the modem or router directly, I get full download and upload speed.

So it must be an issue between the range extender and Windows 10.
