My lap top is very slow approx, 40 on a speed test. Not sure if this computer is a dual band.

Comcast brought there own computer in and it registered 150 on a speed test. Mind the highest was 40.How can I increase the speed on this laptop?

@Neeva1

I think your machine is the following one

   https://support.hp.com/us-en/document/c05825222

It ONLY has   802.11b/g/n (1x1) Wi-Fi® and Bluetooth® 4.0 combo and this adapter can't have higher speed. You can use the following cards

• Intel Dual Band Wireless-AC 3168 802.11 ac 1x1 WiFi + BT 4.2 Combo (non-vPro)
• Intel Dual Band Wireless-AC 7265 802.11AC 2x2 WiFi + BT 4.2 Combo Adapter (non-vPro)

Note: You may need one more antenna to get full benefit of dual band wireless card.

Regards.

Hi Banhien,

  Purchased a Net GearAc 600 Dual band adapter. Speed went up to 200Mbps but not consistent. Some days it goes back to 40Mbps, and when I do a speed test, "Error 43" keeps popping up to download. I'm using Ookla speed test but haven't downloaded the test for Error 43 as I'm afraid of Virsus. Any suggestions?
