Good day,

Thanks a lot for your time and patience.

What is the operating system of your computer, windows 7 or 10?

Did this issue start since you bought it, or just recently?

Would there be any error message when you failed to connect another Wi-Fi?

Have you set up the static IP address on the laptop before?

By the way, since Archer T2U nano is dual-band adapter, did it happen to both 2.4ghz and 5ghz?

If possible, please try to update the following driver:

Thank you very much.

I am using window 7 

this issue is from start ( i bought this on 23rd October 2020)

yes there is an error message when I fail to connect

yes the IP address is static

yes I am using dual-band and having an issue with both

@Kath

still not working after updating the driver 

@pillaiarcher600 

Hi,

May I have a picture of the error message?

And if you used the static IP address,  when you switch to a different Wi-Fi since the IP range might be different, there would be a problem to get connected to another Wi-Fi;

Have you tried to get the IP address automatically, instead of the static IP?

Thanks a lot.

@Kathy_Z I have reinstalled the setup, have updated the driver, have moved closer to router, still keeps disconnecting. sometimes disconnects after a few hours or sometimes keeps disconnect after few minutes

Good day,

Thanks a lot for your time and patience.

Sorry for the delay.

Later we could like to follow up on your case by email and at the same time, could you please help me check the following information as well:

1. What is the model number of your home router?
2. Since you mentioned that there would be an error message when you failed to connect, can I have a screen-shot of the error message?
3. Could you please refer to this link to check the system info and driver info about this computer, such as https://www.tp-link.com/support/faq/2722/ ?
4. When the adapter disconnected, were you still connected but no internet, or the Wi-Fi has been disconnected already and needs to reconnect?

Thank you very much.

1. What is the model number of your home router  = (model = AC5 ) (AC1200 Smart dual-band WiFi router
2. Since you mentioned that there would be an error message when you failed to connect, can I have a screen-shot of the error message?     = if I try to switch to 5 GHz from the 2 GHz channel then the message comes and vice versa 
3. When the adapter disconnected, were you still connected but no internet or the Wi-Fi has been disconnected already and needs to reconnect?                                                                                                                                                                                                            = the WiFi gets disconnected and needs to shut down or wait some time to connect again
4. Could you please refer to this link to check the system info and driver info about this computer,
