WPA2 PSK is used to encrypt packets to and from a router. All the members on the network have the wifi password, so theoritically if one of them is untrustable they could be able to capture and decrypt packets from my machine.

Is there anything to get around this or eliminate this security vulnerability? I guess the only solution would be to use a VPN? Is there any other solution to add another layer of encryption?

Please note that I need a solution for the home/presonal setting, on a limited budget.

  • I would suggest to use a VPN for your whole PC not only for your Browser. In WPA3 this problem will be solved so you could try to change it as soon as possible

  • What services/activity are you trying to protect and from who? Bank activity? Chats and emails? If your service's website uses HTTPS then your typical nosy housemate will not be able to see anything beyond the domain name of the sites you visit. If the site forces the browser to use the best encryption (TLS 1.3) then even a well funded professional can't decrypt the traffic. They can just see the domain you are connecting to and the volume of data you are transmitting... so perhaps they could deduce that you are streaming some video, but they won't know what specific video it is.

Use WPA2-Enterprise (which uses 802.1X). Not only does every user have their own credentials, but their connections are encrypted with different keys. Note that this requires additional infrastructure; a RADIUS server at a minimum.
