    USB adapter shows higher speed than Intel Centrino Wireless-N 2200 (PCIE for desktop)

    ElectricHuman

      USB adapter TP-LINK TL-WN722N shows higher speed (60 Mbit\s) than Intel Centrino Wireless-N 2200 PCIE for Desktop (40 Mbit\s).

       

      On the same PC.

      Router: TP-LINK TL-WR941ND

      Settings on router: DD-WRT, 40Mhz, N-Only, Auto-channel

      Signel quality in both cases is near 50%

      I have tried all settings for Intel adapter in Device Manager

       

      Is the reason only in coincidence of the router and adapter manufacturer (TP-LINK)?

      Upload is very low.

      If the 60 Mbps is for each of two MIMO channels the result will never be 300 Mbps, I think.

       

      But in other utility speed is higher:
