I recently got this internet:
You would think life is good but there's one huge issue. Usually some time in the evening my ping goes to absolute shit. I suddenly get 150-200 ping on servers where I would usually get ~40 during the day. The thing is whenever I do a speedtest, the result is always the same as above. However games become completely unplayable. I've found that using a VPN fixes my ping issues but it's incredibly frustrating to deal with, costs money and can still net me a high ping depending on where the game server is hosted. My firewall is disabled, I don't use an anti virus, I've restarted my PC and router several times (this has been an issue for many weeks). What's going on here? I assume my ISP is doing something with my internet but I'm not sure.
Here's an example...
