Archer T3U dropping connection multiple times per day
Archer T3U dropping connection multiple times per day
This is similar to a previous topic, with Archer T3U USB adapter (hardware version V1) dropping connection repeatedly. In my case, this started happening after Windows 11 updated the driver via a Realtek optional update, I think this was near the beginning of December 2025. The driver version on that update is 1030.52.731.2025. Ever since that time, my laptop will take spells where it shows no internet connection, then a few seconds later it reconnects, then every 10-30 seconds it resets again, over and over.
I had manually updated my driver earlier this year using the file from the TP-Link website, version 1030.44.0408.2024, which worked great. However, I have repeatedly tried to uninstall the adapter/attempt to remove driver/reboot/re-install the 1030.44.0408.2024 driver, but Windows keeps insisting on sneakily re-installing the updated driver, which causes my network connection to again start dropping over and over. This is extremely frustrating, is there any way to stop Windows from repeatedly trying to re-install this driver update? I don't even know what folder the update is stored in - if I could figure that out then I could attempt to delete the file manually (although the new version of Windows seems to think it knows better than I do what I want to do). Any assistance with this is greatly appreciated!

Hi @Synntaxis ,
Is there any update? We have released some solutions that may help you, please refer to Windows System 1030.52.731.2025 May Cause Signal Drop and Instability with WiFi 4/5 USB Adapters.
May I know which version of the adapter you are currently using?
If you reverted to the original or last Windows system driver but did not disable automatic updates, it may still be overwritten later. To provide an effective long-term solution, we may escalate your case to an engineer. We recommend sending an email to forumsupport.usa@tp-link.com with the details for further analysis.
Best Regards~
