Current Router info: Verizon G1100 Quantum Router
Laptop: HP 2000-2b22DX
Operating System: Microsoft Windows 10 (64-bit)

I upgraded my internet speeds with Verizon to 150/150, but after the upgrade, the wifi speed on this laptop is still only giving me 90Mbps. I tried every possible change to the router's settings, but no luck, still getting only 90. This is the same case with other routers that I have tried. I also tried with Netgear WNDR4500 router and Belkin AC1200 Router, same results. What can I do to increase the wifi speed to 150? Do I have to upgrade the wlan card, if it's possible? which one would you recommend? Thanks.

1. The LAN ethernet NIC card on this laptop is 10/100 so the max I am able to get with an ethernet connection is about 89Mbps. This is understandable sincel the max on the ethernet card is only 100Mbps, but wifi as I understand should give me 150Mbps since the wifi/wlan card on this laptop is b/g/n??

2. I have the router in my room about 10 feet away from the laptop.

Even if you get 150Mbit link speed (you can check that in network manager, or task manager), you will only get about 1/2 that speed in throughput. Why, because WIFI is not full-duplex. Your laptop can only send OR receive at any point in time. So up to 1/2 the time is spent waiting to send or receive. To get 150Mbit throughput you need 300Mbit link speed.

but I was getting 75Mbps wifi speeds when my internet speed was set to 75/75 with verizon before the speed upgrade. Actually, is it possible to just upgrade the Ethernet card on this laptop to 10/100/1000 and get the 150Mbps speeds? I don't necessarily need to wifi. thanks.

You can get a USB ethernet dongle. 10/100/1000.
$15 and up:

Thanks. I'll check into this and also maybe a high speed USB wifi dongle. Thank you all for your help!
 

Full vs half duplex can make a difference, but not in this case.

As best as I can tell, that laptop only supports 2.4 GHz WiFi.
https://h30434.www3.hp.com/t5/Notebook-Wireless-and-Networking/WiFi-Connections-HP-laptop-unable-to-find-5Ghz-wireless/td-p/3300523

The problem is 2.4 GHz is so narrow and crowded that it's virtually impossible to use the wideband 40 MHz capability of 802.11n at 2.4 GHz. Consequently, its max nominal connection speed is 150 Mbps. That is the link speed, not the data transfer speed. About half of that 150 Mbps is used for error correction algorithms. So it can hit 75 Mbps easily, and based on your experience it can manage to eek out 90 Mbps. But that's it. The rest of the bandwidth is being taken up by error correction coding which can't be turned off.

If you could use 802.11n's wideband capability (using 40 MHz of bandwidth instead of 20 MHz), that would bump up your link speed to 300 Mbps, making 150 Mbps data transfer rate possible. But it's highly unlikely to work at 2.4 GHz.

Both the Negear and Belkin routers you've listed are dual band, so support both 2.4 GHz and 5 GHz. So a laptop which supported 5 GHz 802.11n might be able to get 150 Mbps data rate. But as this laptop's WiFi card doesn't appear to support 5 GHz, your only option would be to upgrade the WiFi card. Unfortunately I can't confirm exactly what WiFi card this laptop uses (there's a common mini-PCIe style which everyone uses nowadays, and a really old larger style which isn't supported anymore). The best I could find was this video. Watch it and see if it appears to be the same as your laptop.

If it's the same, then yes you can upgrade the WiFi card. It's just like replacing a PCIe card on a desktop. You swap the hardware, then install drivers for the new hardware. I'd recommend a 802.11ac WiFi card, as that is more likely to be able to hit 150 Mbps than 802.11n. That 40 MHz wideband feature of 802.11n doesn't always work. And your Belkin router supports 802.11ac.

Ok. I'll see if I can install a 5 Ghz band compatible ac wifi card in this laptop. Thanks!

UPDATE:

It seems like this laptop is not compatible with dual band wifi cards. I'll have to settle for the gigabit Ethernet dongle.

Success! I'm now getting 150/150 speeds with the "Plugable USB 2.0 to Gigabit Ethernet Adapter". I might buy a high speed USB WiFi adapter later on. Thanks guys.
