Disable your VPN
Although VPNs are important security tools, they can slow down your network connection.
Technically speaking, using a VPN doesn’t directly affect your Wi-Fi signal, but since it does force all your traffic through the VPN provider’s servers, your internet speed can definitely be impacted, especially if you’re using a cheaper VPN service that can’t keep up or you’re using an exit point in a country that may not have the best infrastructure on the other end.
So, try disabling your VPN if you’re using one. If you see a difference in performance and you’re uncomfortable not using a VPN, you can try working with your VPN provider to get a better connection or try a more premium VPN service.
