Hello
I just got the D-Link DWA 171 AC600 MU-MIMO USB wireless adapter for use on my desktop. About every minute I get a 3000 ms lag spike. I tested with my laptop connected to the same network in the same area with no problems.
I've googled and downloaded the most up to date driver for this adapter with the correct hardware version "C1" and the drivers for my motherboard.
I've also tried disabling the WLAN autoconfig as detailed here:
https://answers.microsoft.com/en-us/windows/forum/windows_7-networking/how-to-disable-wlan-autoconfig-for-proper-internet/fd8da170-5c68-e011-8dfc-68b599b31bf5
I've also searched this and other forums for similar problems and tried many solutions with no luck. Wondering if anyone else here has had this problem and found a solution. Thank you

Be sure the adapter driver is up to date from here:
https://support.dlink.com/ProductInfo.aspx?m=DWA-171
What mfr and model host wifi router is the adapter being connected too?
Is this seen with other wifi routers?
Connect it to a different PC or laptop to see if the problem follows.
-
Thanks for the reply,
I fixed it actually by disabling windows update in services.msc, in case anyone finds this later.
All I know is that it's a router from Telus.
-
Interesting. Glad that fixed it.
Enjoy. ;)
-
I have the identical problem, also with a Telus Wifi router and DLink AC600...
Disabling Windows Updates does not fix this for me.. is there not a better way to remove this 3000 ms pause every minute?
-
I have sent a support request to DLink technical support in Canada and will report back if I get a resolution.
Now that I have trapped a few pauses with Procmon, I can state that my pauses are precisely 4000 ms, not 3000.
They start with:
2021-06-13 9:13:38.4159618 AM DeviceIoControl\Device\MUP
And end with
2021-06-13 9:13:42.4129500 AM DeviceIoControl\Device\MUP

Let us know how it goes...

I will.. thus far I am getting questions rather than answers..
-
At least there interested and reviewing it. Keep on them about it.
-
There appears to be a timer involved... exactly every second, there is a DeviceIoControl\Device\MUP command, and every 60 seconds this leads to 4 seconds of download interruption.
Is this a Windows thing? Or is the DLink driver triggering this?
-
Don't know...
If you can find the chip set mfr, Qualcomm, Realtek, Atheros...You could try to download chip set mfr drivers from them directly and see if you notice any differences. I know that Realtek and I believe Atheros have drivers for there chip sets. Not sure what model is in the 171 though. I know years ago someone posted using chipset drivers for I think the 131 or a older model DWA that worked vs using D-Links drivers. If you can see or find the model of the chipset, might be work testing to compare and let D-Link know. Maybe ask support what chipset this is using.
What Rev is your 171? A B or C?
-
I found the following:
Rev A is Realtek RTL8811AU
Rev B is MediaTek MT7610U
Rev C is Realtek RTL8811CU
-
Mine is Rev C. Will give Dlink support a chance to respond... I am way out of my depth here.
I checked the driver, mine is actually newer (directly from DLink support). 1030.40.xxxx
For downloads, it does not really matter, but for Zoom meetings, a 4 sec pause every minute gets annoying..
-
You might try this while you wait on D-Link and see:

-
When I try to install the driver, Windows says that "it has determined that I already have the best driver installed" and does not allow me to proceed.
-
Did you remove the prior version first?
-
Windows is not letting me... time to be patient, I guess..
-
Windows didn't let you remove the current driver or did you use the Un-install feature in Programs and Features to remove the installed driver package?
-
OK, you may be on to something... the Uninstall in Programs worked, and I was able to install the Realtek driver.
Appears to be working better for a test download.. Have a Zoom meeting coming up.. Will let you know!
Edit: Nope, problem persists.. reinstalled the DLink driver... Also better, at first... Maybe something is flakey here..
Works for a while and returns to its one minute interruptions later..
-
Wonder if your Adapter HW maybe faulty.
Can you try the adapter on a different PC or laptop by chance?
Would need another 171 adapter to test with to see if same thing happens...
-
Well, now trying a Netgear USB adapter and getting the very same 4 sec pauses.... guess it was not the 171..
The OP said that he fixed it by disabling Windows Updates in Windows Services, but that has no effect here, whatsoever..
Wonder what he meant??
-
Are you still using a Telus Wifi router?
-
Hi, thanks for sticking with this... Yes, I am still using a Telus WiFi Hub, just like the the OP... which got me thinking that we might have the same issue.
Have sent him a PM, but no reply. Sending you a PM as well.
Back to troubleshooting..
I can run Zoom on a laptop or a tablet, using the same hub without problems, so it is specific to my Win 10 PC.
In the procmon traces, I can see a definite 4000 ms window every 60 seconds.

There is an exact timing sequence here... 4000 ms - every 60 sec
Wonder what is triggering this..
-
I would try a different wifi router or a WiFi unit that has AP mode abilities. Disable ALL wifi radios on the Telus router and connect up the wifi AP unit and see if this happens using a different wifi system.
Could be something in Windows as well. Happen to have a different PC to test with?
-
My next step is to try an internal PCI Wifi card, instead of the USB adapter.. should arrive tomorrow..
A CAT5 cable connection to the router is the only good solution I have found, but I am in a separate room.. so not practical.
-
I would recommend CAT6 at least.
Possible alternative would be to setup a Power Line adapters between rooms then ethernet using them as a suggestion.
-
Just installed this:
https://www.asus.com/Networking-IoT-Servers/Adapters/All-series/PCE-AC58BT/
And as best I can tell, my problem has disappeared :)
Will report back after a few days of real world usage.. but looking good!
-
Nice adapter.
Something to let D-link support about know that using something different doesn't seem to produce the problem.
-
Please consider this case closed... the solution was to remove the USB Wifi adapter and replace it with a PCI slot motherboard adapter.
Solid performance, no more pauses :)
-
Enjoy. ;)
