this past week i have been getting lag spikes

Could you try the steps on the Connection Troubleshooting Guide? Let me know if anything helps.

same, it has only been this week though. but it doesn't say I have lag, my screen just gets all weird

Same-- my lag has been horrible. On my screen, it says my ping and fps are fine (they're my usual) but it feels like 1k ping. Everything happens 2 seconds late and I'm "attempting to reconnect" like every 3 seconds. I've tried everything-- disabling ip helper, disabling firewalls, flushing dns, resetting my router, but it isn't changing a thing. Not sure if this is an issue of Riot's end or mine.
