Hi Collyire, For your case, may I know if all your devices can not get such a low speed? How many device is using the internet from TL-MR6400? If you run a ethernet cable and connect the yellow port from the back of MR6400 to your computer, what's the speed you can get? If only wireless speed is slow, you can try to change some wireless settings, such as channel and channel width. You can refer to the following link to get some help: https://www.tp-link.com/en/faq-2292.html Merry Christmas:)
