Hi all,

 

My USB Adapter T3U AC1300 cannot find the shared wifi connexion of my Samsung A52 5G when it's set to 5Ghz.

No issue when it's set to 2,4Ghz.

 

Latest driver installed for my adapter.

 

Anyone else with the issue ? And any potential solution ?

 

Thanks

Stéphane

@WillCoyotus Hello,

 

It is recommended to check if Samsung hotspot Wi-Fi is transmitting on channel 149 to 161.

Tp-link wireless adapter (EU) version only supports Band 1-3, not Band4 channels (149-161 ) and that could be the reason why 5Ghz hotspot is not detected.

 

You could also contact Samsung support and see you could change hotspot 5Ghz channel to channel 36/40/44/48:

 

Here is similar post that may help explain:

@Solla-topee Hi

 

That's definitively the problem. The Samsung A52 transmit only on channel 149, and there are no way to change this in the phone's settings.

 

All my devices can connect to my phone, and it's only the T3U which can't.

Too bad the EU version of the adapter doesn't support Band 4 channels. I will send it back and find another wifi usb adapter.

 

Thanks for your answer.

@WillCoyotus Good day,

Thanks for confirming. Tp-link adapters (EU) support band 1-3 which comply with CE certification and Band1-3 channels are also commonly taken up in European countries.  

If Samsung phone hotspot has to work at Band4 channel I‘m afraid you have to consider an adapter of another made which supports band 4. 

Thank you for previous support for  tp-link products ~
