Hi brummiearab1, welcome to the forum. I'm sorry to report that your card can only connect in the 2.4 GHz band. If you can set your card for the 40MHz bandwidth, the theoretical maximum data rate is 150 Mbps.
Otherwise in the 20MHz bandwidth, 65 or 72.22 Mbps is normal. To connect to the 5 GHz band, the card must be rated as A/B/G/N, or AC.
There are 4 cards in your HMM, and all 4 are only rated as 1x1 BGN. There are no cards that have 5 Ghz capability. 13 WLAN,WiFi 1 × 1 BGN,Cbt BCM94313HMG 1 × 1 BGN HMC 20200102 N 13 WLAN,WiFi 1 × 1 BGN,Liteon HB125 1 × 1 BGN HMC 20200223 N 13 WLAN,WiFi 1 × 1 BGN+BT4.0,Cbt BCM943142HM 1 × 1 BGN+BT4.0 HMC 20200222 N 13 WLAN,WiFi 1 × 1 BGN+BT4.0,Liteon WB225 1 × 1 BGN+BT4.0 HMC 20200224 N Here is a support doc to help you understand the data rates: Cheers DragonRider.
