Wifi Speed Discrepancy on 2.4Ghz and 5Ghz

[phantom1421]

So I have Verizon FIOS 75 down and 75 up. I use verizon's newest router available, the quantum router with dual band wifi, and it has AC.

I have been testing my wifi on my desktop a floor above my router with both bands and have noticed the huge difference in speeds between 2.4Ghz and 5Ghz. I have a custom built PC with the TP-Link Archer T9. I was wondering if anyone has any helpful advice on how I can increase the speeds on the 2.4Ghz band, and good settings to put for router and or wifi card.

I also got my network card replaced and it same results overall.

What is the link speed showing as on your device for 2.4Ghz. You will always get better bandwidth if within range of 5Ghz. (2.4Ghz has better penetration than 5Ghz).

When i am on 2.4Ghz i get about 10mbps to 30 mbps for both down and upload, but when I'm on 5Ghz i get a full 75 to 80 mbps. And my router is just a floor below, my bedroom is above the kitchen with windows which hopefully gives a sense as to how close i am. Also i was thinking about getting antenna cables to extend with wires and place the antennas in different places, would it help?
