My xfinity internet plan was recently upgraded from 200 DN/5 UP to 300 DN/10 UP. I didn't see any difference in speed tests, so I contacted xfinity support. The tech did some update on their end and had me disconnect the cable and restart the modem. My upload immediately doubled to a consistent 10-12. However, my download stayed at the previous normal range of 130 to 160. The tech said I should be seeing at least 230 to 240. He ran some tests and said everything was good on thier end, so the problem must be my router. I checked to verify that router was running latest firmware/driver. Not sure what to do next. Any suggestions?

I use the windows speed test app or the ookla website. Get same speeds either way. My laptop does not have a port for wired connection, so I am testing with the wireless connection. Was considering using another laptop to test with wired connection. Haven't had access to that yet. I just figured if the upload changed (doubled), I should have seen some difference in download.

My laptop is a Lenovo Ideapad 720S-13ARR. It is running on AMD Ryzen 5 2500U processor with 8 gb RAM. Is there a particular wireless network card that you would recommend as an upgrade?

The question of speed is answered. I did the wired test. Ran it three times. Over 360 mbps download each time. So xfinity is supplying on thier end. If I want more from my laptop, I'll have to do an upgrade. Thanks so much for all the information and advice. Take Care!!

My laptop is a thin 13 inch style. Am I correct in assuming that the network card is built into the motherboard? Therefore not replaceable or upgradable? I guess that would mean needing an external (usb) adapter to increase the speed.

how are you testing speeds?

What device, site, are you testing on?
Wired? wireless?

    test your wired connection.
    
    Many factors influence wireless speeds. LIke if your laptop has a simple 1x1 wireless card in it versus a 2x2 antenna setup. Or if theres wireless interference, etc.
    
    So first test wired to see if the device is getting its full speed.
    
    If it is, then try other devices.
    
    What actual wireless card is in your laptop?
