Not Getting My Full Upload Speed

According to my plan's Facts, I should be getting around 300MB upload, but I can only get about 40 MB upload.

I am on a desktop that is using ethernet. Ethernet is connected to the modem. The coax is connected to the modem directly with no splitters. I have tried resetting the modem.

Can someone help me get better upload speed?

It appears that my modem is too old to get the full upload speed. Xfinity support said I could buy a new one or they could send me a new one for free.

Modems that I was told should work would include: Hitron CODA56, Netgear CM3000, ARRIS G54, ARRIS S34, Ubiquiti UCI.
Also, there own routers: XB7 or XB8.
