To add to aeribus's answer, replacing your router can definitely help. Depending on how your network is set up, if you currently have an ONT (Optical Network Terminal) set up, along with a wireless router, you may call your ISP to ask if they can replace your current wireless router with a wired router.
In case they cant provide you with a wired router, ask if you'd be able to buy your own wired router and have their technician set it up for you. I'm currently in the process of getting a wired router since routers are beneficial in that they provide your LAN with NAT - good for security.
Depending how far you'd want to go wireless, many enterprises have stringent rules regarding their wireless systems. Many go so far as to removing the WiFI cards from their computers.
A VPN would help keep your anonymity safe. Private Internet Access purportedly dont log their users data, and they have various servers around the world, albeit some slower than others.
