I changed my internet 300 to 600 and it looks like just 300 plane.
Modem also change to XB6 and it work fine.
I don't have 3rd party hardware I just direct connect to my PC and Wifi for my family phones.
I'm using cat5e cable. Do I need change to cat6?
Anyone can help me?

That's definitely lower than we'd expect if you're testing a direct wired connection. Have you tried power cycling the modem? It's possible that it just needs to be refreshed to show the correct speeds. To do that you can simply unplug it for 30 seconds and then plug it back in. Once that's done, please try running another test. If you don't see any improvements then we'd suggest having our customer support team check the account to make sure the upgrade has gone through.
