Good day.

Thank you for your patience.

For your case, could you please help us check the following information:

1. What is the IP address when the computer lost internet connection?
2. Could you please help us check the system info on the computer
3. What Is the model number of your main router?
4. Did both 2.4ghz and 5ghz have the same issue?

Then , please refer to the following suggestions:

1. Change the advanced settings of the main router, such as channel 11, channel width 20mhz for 2.4ghz, channel 40, channel width 40mhz for 5ghz;
2. Update to the following driver:  https://static.tp-link.com/2019/201911/20191128/00011389-RTLWlanU_WindowsDriver_1030.29.1102017_DUA_tplink_0719.L (1).zip

Thank you very much for your understanding and support.

@Kathy_Z Thank you for your reply.

Answering your questions:

1. 192.168.1.18

2. Here is the system specifications:

         Operating System: Windows 10 Pro 64-bit (10.0, Build 18362) (18362.19h1_release.190318-1202)
      System Manufacturer: MSI
             System Model: MS-7917
                     BIOS: BIOS Date: 02/16/16 09:38:11 Ver: V1.13B0 (type: BIOS)
                Processor: Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz (4 CPUs), ~3.5GHz
                   Memory: 16384MB RAM
           Card name: NVIDIA GeForce GTX 970

3. The router is SAGEMCOM F@ST 3184

4. This router only supports 2.4GHz.

Your suggestions:

1. I did change from the default channel (position 6) to channel 1 with 20 MHz, as I only have access to 2.4GHz. it did not change the behaviour.

2. When acessing the site https://static.tp-link.com/2019/201911/20191128/00011389-RTLWlanU_WindowsDriver_1030.29.1102017_DUA_tplink_0719.L (1).zip I get the following message:

thank you

@Kathy_Z Opening up the link gives me the same page. Right clicking and selecting Save Link as, the download fails due to Forbidden reason.

@Kathy_Z Hello Kathy,

I was able to download the drivers. I couldn't start the setup file since I get a NSIS Error - Error launching installer.

Nevertheless I was able to update the drivers using the ones on the Windows_10_64bit folder.

So far everything is working. If it stops working I'll try the static IP address. I'll advise you if the connection drops again.

Thank you,

@Kathy_Z As everything is working so far without any issues, I'll mark your post as the solutions. The drivers did it for me.

Thank you again for your support!

Hello,

 

Not sure if there is an existing topic already opened regarding this issue, if there is please link me to it.

 

I have purchased the Archer T3U Plus AC1300 usb wifi adapter to use with my desktop computer running Windows 10. At first the system did not recognize the adapter so I had to download the drivers from the website using another computer. The drivers were downloaded from the following link: https://www.tp-link.com/en/support/download/archer-t3u-plus/#Driver

 

The adapter was working without any issues for a couple of minutes/hours and then I started losing my internet connection. Running Windows troubleshooting, the wifi adapter was reset and the reason that Windows gave was that "Default gateway not available". Similarly, If I unplug the adapter from the USB port and plug it back in, internet works again for a more couple of minutes. I've tried switching from all the USB ports - 2.0 or 3.0, front or back of the desktop - but they all gave the same result. The power saving options is disabled for the adapter as well.

 

I'm very close to the router and other laptops / phones in the house do not have any issue.

 

Could you please help me figure out why the adapter is always losing the connection?

 

Thank you.
