Randomly a few days ago I started getting spikes from 40 ping to 150 every few seconds nonstop all day and can't play any games online. I've restarted my router a few times but it didn't fix it. I normally use an ethernet cable so I tried switching to WiFi and nothing changed. I called my ISP and they told me that my internet is fine and nothing is wrong. Is there something I can do on my end to fix it?
