when sharing data from my phone-data (hotspot) to windows pc, Archer T3U is not finding 5-GHz network.

 

it does find 2.4-GHz network though.

 

can anyone help me?

 

t3u does find another 5-ghz network. however, not the 5-ghz from my phone.

 

other devices does find my phone 5-ghz network also.

Hello   @link13 

 

Please check the country version of adapter, it is (EU) or US version? For 5Ghz Wi-Fi, it is recommend to set WiFi channel on 36/40/44/48.

It is recommend to download Wi-Fi analyzer APP or inSSIDer and scan for the wifi channel of mobile hotspot Wi-Fi and see which channel the Hotspot WiFI channel is currently usaing: 

Why cannot the adapter detect the 5G Wi-Fi of my router?

 

May I know the modol and OS of the mobile phone?

Hello  @link13 

 

Channel 11 is the 2.4Ghz Wi-Fi channel, you could select  5Ghz Wi-Fi band and see if the channel is on 36/40/44/48. 

If not it is possible that Hotspot Wi-Fi does not work on the adapter supported 5Ghz channel, you could consider 2.4Ghz Wi-Fi band when use hotspot.
