I am currently looking for a solution to internet speed problems.

I recently moved into a townhouse, and set up an internet connection with my ISP. I receive 300mbps, but in my office across the house and one floor up I only get 30mbps on a speed test. I believe the problem is that there are too many walls between myself and the router. I was wondering if getting the TP-Link Deco XE75 would solve my problem.

I don’t have a better place to move my current router to, and I would prefer to not run any ethernet if possible. Thanks for any help you guys will provide!
