Homebuilt PC getting 1/3 the internet speed of laptop

Troubleshooting

I have an internet connection of 150 mbps down.

My work laptop is getting about 140 mbps according to speedtests, but my homebuilt desktop is only getting 40-50.

They are right next to each other in the same room.

I'm using two different network adapters and getting the same results.

one of them is this

and the other is something along the lines of this I bought it several years ago.

Could anything other than my wifi adapter bottleneck my download speeds?

The laptop has the USB adapter, right? It's dual-band and has a lot more bandwidth than the 300Mbps PCIe one.

no the laptop has it's own built in wifi card.

The usb adapter is new and I was hoping it would solve the low DL speeds that I assumed were from the old PCIe card.

Maybe I worded this poorly.

The desktop has the old PCIe card and was getting low speeds so I bought the new USB adapter. it also gets the low speeds.

My laptop is completely separate and is about a year old and gets ~145 mbps.

I take it the 2.4GHz adapter is on your desktop? That's probably the problem. 2.4GHz is often extremely crowded, especially if you or anyone around you is using an overlapping channel.

the 2.4 ghz is an old adapter, I noticed the low dl speeds so I bought the new USB one that supposedly gets up to 600 mbps. I disabled the old pcie one and the usb one still gets the same results.

does just having the old PCIe one plugged in cause an issue?

What's your AP?

Oh boy, one of those pieces of shit.

It is dual band so assuming 5GHz penetrates to there, you should get something halfway decent.
