Poor connectivity making online gaming impossible
When my son tries to play Valorant on a Windows laptop, it struggles to connect to the Riot Games servers. Sometimes he gets connected and starts a game, then gets disconnected shortly afterwards. We see the same behaviour on 2 different laptops. We've applied all Windows patches and updates, changed DNS config, rebooted our Hub 3, and tried multiple other suggested fixes. All other broadband access is fine, we get download speeds of 300+Mbps. Only when gaming do we see connection issues.
Riot Games have been helpful, but after trying various things, their conclusion is that it's an ISP routing issue. Their route info is here: https://www.peeringdb.com/net/5918.
Not sure if posting here is the best way to progress this issue? Should I be raising a support case with VM? Is there more diagnostic info that I should provide? Thanks.
