Frequent latency spikes

Honestly this happens to me every few patches or so. Nothing works, and support never really can help. You just have to wait for a new bug fix/patch and hope it fixes what messed it up for you.

Keeps happening to me, lag spikes every few seconds to 3-400ms... unplayable.

Have exactly the same problem, was fine yesterday at league start, today its unplayable.:(
Its not just 1 gateway, all of them randomly go up to 300-400ms for 1 or 2 seconds. My Internet Connection is fine, checked it. Must be Server side.

same thing happened to me.. restarting my wifi router helped.. i think it was something with my Killer wifi card vs. router..
