We will do some troubleshooting first:

1. What is the speed you can get from the TL-WR941HP by wired cable and wireless separately? You can run a speed test for 3 times with computer connected to it.

2. Meanwhile, please verify its wired/wireless negotiation speed as the instruction: https://www.tp-link.com/support/faq/2265/

Note: For wired negotiation speed, it is the same; while you need right click on local area connection or ethernet. 

3. Please ensure that the current firmware is up to date.

4. Besides, you can refer to the instruction below to narrow down the issue.

5. Try to change the wireless settings to optimize its performance, like wireless channel and channel width.

Thanks in advance, and have a nice day.
