When encountering slow internet speeds with the TL-WN881ND wireless adapter, there are a few additional steps you can take to troubleshoot the issue. Firstly, ensure that your computer's power management settings are not affecting the adapter's performance. Set the power management option for the wireless adapter to "Maximum Performance" to prevent it from entering power-saving modes. Additionally, try changing the wireless mode on your router to "802.11n" only, as this can optimize compatibility with the TL-WN881ND adapter. Lastly, if possible, try using the adapter on another computer to see if the issue persists, as it could be a compatibility issue with your specific system.
