Using any VPN on this PC causes severe lag to entire network

Alex 20 Reputation points

It started 2 days ago. The second i open any website or a youtube video, or start any app that uses bandwidth, all computers and devices in my apartment, including PC im using it on, suffer extreme lag which basically disables everyone from using internet; The ping to google jumps from 25 to 300+, next second to 1000-3000+.
I tried 2 different VPNs, different locations, resetted my network settings, run CCleaner, reinstalled VPN, nothing helped.
Happens only when im using VPN from this one particular PC (win10) (tried on another, everything works fine).

My internet speed without VPN is 33 MBs ( 260+ Mbs) per second for downloads, and 3,3 MBs for uploads.

    They are using different protocols like OpenVPN, WireGuard , TCP, have you tried using different protocols and see if that make any different?

    Try open start and search for feedback and open the Feedback Hub app and report this issue.

    I advise you to contact the ProtonVPN support, have a look at:

    For Windscribe, you may contact:
