Pingplotter is currently the best tool to investigate connection issues. Let me know if you have any issue with support so I could escalate it if needed.
When it comes to connection issues most players think that it's WG to blame for any disconnects but it's not that simple. The most important part is to understand where these issues occur. If that's your router or network settings - it should be fairly simple to resolve. If any issues on the server - we can reach out to the appropriate team. But very often problems appear on the ISP side and those are a little harder to deal with since ISP generally don't recognize these issues unless you provide them some proofs. Support is there to help you no matter where your connection issues appeared
