Hi vinodhkumarl,

 

Welcome to the Community Forums.

 

Checking on the parts lookup page, your WLAN adapter card is with part number 20200570 Cbt RTL8723BE 1x1BN+BT4 PCIE M.2 . Specification of this card only support operating channel at 2.4 GHZ.

 

If you are expecting a different WLAN card performing at 5GHz, then it would be best to call in the store to verify your purchased parts.

 

Regards
