WiFi key disconnects after a few minutes

Question

Hello, since a Windows update, my Wi-Fi key keeps disconnecting constantly! When I run the troubleshooting, I am told every time "default gateway is not available" then it resets the network card and voila, the connection comes back for a few minutes then goes away again. The drivers for the key are up to date even though the software (small CD) does not work with Windows 10. Can you help me?

Hello, it's the same for me on W7 for a week now when everything was fine! I think it could be the mixture of waves that might disrupt the wifi (microwave, phone/smartphone, digital terrestrial television, radio, ...)  -- Forum users are not fortune tellers, at least I'm not!

USB\VID_0BDA&PID_8178&REV_0200 or: USB\VID_0BDA&PID_8178 I suppose that's what you're asking me for; otherwise, the wifi key is a TP-Link Model TL-WN823N.

re  check the version of your Wifi Adapter (V1/V2/V3)  on this page, you have the driver for W10 for version V2 and V3 >> https://www.tp-link.com/fr/support/download/tl-wn823n/#Driver  download it to your desktop and unzip it with 7zip (for example)  the link >> https://www.7-zip.org/  PS: take the one corresponding to your PC (32 or 64 bits) >> https://www.commentcamarche.net/informatique/windows/169-32-bits-ou-64-bits-comment-savoir/  once done, open the unzipped folder and run SETUP.EXE as administrator (right click)  if you have any questions...  ========================  @ tyranausor  do the same thing and let me know how it goes (if your Adapter is the same)  @+

It seems to me unfortunately that this is a Version 1, so no W10 version...

re  Unfortunately, it seems to me that this is a Version 1, so no W10 version ...   it's written on the Adapter or on the CD, and if it is indeed version V1, there is indeed no driver for W10  @+

Noounoours · Answer

It says version 1.2 so V1 anyway, right? But how is it that everything was fine before a Windows update? I've been on Windows 10 for quite a while and it was working perfectly well.

re  But how can it be that before a Windows update, everything was fine? I've been on Windows 10 for quite some time and it was working superbly well.  Good question  What version of W10 do you have? (1803 or 1809)  Click on the Windows+R keys  In the window that opens, type WINVER and click OK  @+  -- The radiation level is higher at the employment center than at Chernobyl.

Noounoours · Answer

No, it didn't work :/ Can we force the network gateway to be available? The problem might not be with the drivers...

billmaxime · Answer

No, it didn't work :/   Did you get an error message?  Can we force the availability of the network gateway? The problem may not be with the drivers...  I'll give you another manipulation later  @+  -- The radiation level is higher at the unemployment office than at Chernobyl.

Noounoours · Answer

That's what I did in the previous operation, sorry... It didn't detect the zipped file, so I unzipped it, thinking that's what you wanted :)

billmaxime · Answer

re  that's what I did in the previous operation, sorry ... It didn't detect the zipped file so I unzipped it thinking that’s what you wanted :)   okay, but I didn't suggest selecting the file >> netrtwlanu.inf  so you just selected the CAB folder  repeat the process by selecting the file >> netrtwlanu.inf  let me know what it gives  @+  -- the radiation level is higher at the employment center than at Chernobyl

no more error message

billmaxime · Answer

re

ok, since you have a Wifi Adapter, I assume that your PC is a desktop (tower)

do this:

in Cortana, type CMD

in the search result, right-click on CMD >> run as administrator

in the window that opens, type these commands one by one and click ENTER after each command

ipconfig /flushdns
netsh winsock reset
netsh winhttp reset proxy
netsh winhttp reset tracing
netsh winsock reset catalog
netsh int ip reset all
netsh int ipv4 reset catalog
netsh int ipv6 reset catalog

when that's done, restart the PC and see what happens

Noounoours · Answer

No, it doesn't work...

billmaxime · Answer

re  No, it's not working...   this is bad...  since you don't have any alerts in the device manager, and I've given you the latest driver for W10 for your adapter...  the link to the page >> http://www.catalog.update.microsoft.com/Search.aspx?q=USB%5CVID_0BDA%26PID_8178%26REV_0200  I don't really see how to solve your problem...  do this again:  close all your running programs  start the command prompt as an administrator (right-click)  in the window that opens, type SFC /SCANNOW and press ENTER  WARNING: there is 1 space between SFC and /  let the PC work (about 20 minutes)  at the end of the scan, check if it found/fixed any system files  @+  -- the radiation level is higher at the employment office than at Chernobyl.
