PC goes BlueScreen after installing TPlink Driver
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Recently i bought this adapter , when the first time i plug in without installing the Official driver it works properly i guess,
and after a while i realize that the adapter didn't perform like what in the paper state, my wifi internet speed is 500mbps but when i speed test its only 200+ or even lower than that,
so i thought it maybe because of the driver so i installed the latest driver , and it works , the speed is good 450 - 490 mpbs , BUT whenever i do heavy download or stream 4k movie the adapter disconnect the wifi randomly , not the usb disconnected but the wifi connection, so i installed the EU version of driver and its LESS troublesome from disconnected , BUT after while the pc goes Bluescreen randomly at first , then it bluescreen in Sign-in pc after boot up , it looped like that , if i unplug the adapter its okay but after i plug-in it goes bluescreen. after i did the solution from internet nothing works , changed the driver version multiple times still didn't work and got slapped with Bluescreen . so i decide just to use the windows default driver BUT it didn't work too! . the windows default driver is corrupted something like that , so i experiment a bit to get back the windows driver work again , heres what i do : i installed the official driver first , then i uninstall it back while the Adapter is still plug-in , then the Windows default driver replace automatically afterward , then i got the adapter works fine back using windows driver at a cost of losing 300mbps of my 500mbps internet speed. i don't know the solution for this. but i suspect that i remember the windows has update back then , and after a while the bluescreen came up. is it my PC the issues or the TP-Link Driver is the culprit.
Hi,
If I may share some personal experiences with this type of USB wireless adapters.
According to information on the Internet, what makes the Archer T4U V3 work is a silicon chip called "RTL8812BU", made by the company "Realtek".
First of all, no matter if you are using the driver installed by Microsoft Windows itself or downloaded one from TP-Link's website or downloaded one from some other driver website, all the drivers for the Archer T4U V3 were made by Realtek. The same also applies for all other hardware manufacturers who make similar wireless USB dongles based on this chip. What the hardware vendors might do is to embed the driver files provided by Realtek inside an installer software that shows their brand name and company logo.
For some reason Realtek apears to have been struggling to implement proper USB 3.0 support in their wireless products.
I don't know the exact tipping point, but until around the version "x.x.x.2019" drivers Realtek apparently didn't support USB 3.0 mode for the RTL8812 at all. At the time I found out about that because I also faced the problem that the data throughput speed was limited to below 300 Mbps with my RTL8812BU-based Wi-Fi dongle.
I think it must have been with one of the "x.x.x.2020" drivers when I noticed that my RTL8812BU Wi-Fi dongle suddenly did operate in USB 3.0 mode and data throughput speeds went up.
However, while for me Realtek-based USB wireless adapters have worked nice and stable in USB 3.0 mode on Intel-based computers, that was not always the case when the wireless adapters were used on AMD-based systems.
Anyway, please check in which USB mode your T4U is running when it is slow and when it is fast but unstable. It may (or may not 
) come down to what I wrote above.
As for checking the USB mode currently in use by any device. There are probably several ways to do it, but I suggest using a utility called "SIV - System Information Viewer", which is a small download, free for home use and doesn't require installation (just need to decompress the downloaded file).
Note that it is sometimes necessary to actually establish a connection to a wireless network before the Realtek-based wireless dongle switches itself from USB 2.0 to USB 3.0 mode.
