VERY slow speeds with a 300 Mbps connection

I have a 300 Mbps connection to my old HP Pavilion PC. With a usb wireless adapter, I get 200 Mbps, but with the USB3-E1000, I only get 20 or 30 Mbps. Any ideas on what to try? I just got it today, I’d hate to send it back already.

Hello Jim,

Thanks for contacting us! I apologize for any trouble you’ve had, and I am here to help! I’d like to take a look at how the adapter is interacting with your computer. If you would, please make sure the adapter is connected to the PC and run our diagnostic at the following link: A zipped folder with the results will be placed on your desktop after running the tool.

If you would, please respond to us directly at: with Ticket # 262419 in the subject line, and attach the diagnostic results for me to review. I look forward to hearing back from you soon.

Thank you,

Product Owner
