Bad internet quality, Don't know what else to do!

Your issue is caused by a routing or peering bottleneck between Videotron and your employer's server, which explains why local speed tests look fine while your workplace connection suffers from high latency and packet loss. To address this, try running a reputable VPN or Cloudflare WARP to force a different network path if latency drops, Videotron's default route to your company is degraded. Additionally, disable "Advanced Security" inside the Helix Fi app (as it can throttle PCoIP/UDP streams), switch to a standard Cat6 cable to avoid shielding issues with cheap Cat8 cables, and ask your company's IT team to aarp membership run a traceroute (tracert) to check if their gateway or firewall settings recently changed.
