Upgrade your Wi-Fi router
If you've exhausted all other options, it may be time to bite the bullet and upgrade your networking hardware itself. If you've got an ageing router that can't take advantages of new technologies and faster connection speeds, it could be holding your Wi-Fi back.
This is especially true if you're still using the default router supplied by your ISP. Newer models are slightly more capable, but older versions are likely to hamper your internet experience significantly.
