Extremely slow upload speeds

[ktaulbee]

My download speeds are 200+mbps, but upload is around .09 mbps. Essentially, nonexistant. If this is due to the number of people working from home during the pandemic, then it is what it is. But if there's something I can fix I would love to know. I am frequently driving to my office just to upload digital content for my job. 

I saw a thread where someone purchased a new modem and got a huge improvement, but my equipment is pretty new and decent quality. The upload speed has consistently been 5mbps (which is very slow) for years, but now it is useless. 

Modem: ARRIS Surfboard SB6190

Router: Netgear Nighthawk AC1750

Any suggestions would be greatly appreciated!

Is this with a WiFi connection ? If so, for a test, does a computer hardwired directly to the Nighthawk router with an ethernet cable have the same problem ?
