Ever since what seems to be the syndra patch I'm experiencing 160+ ms ranging from 160-300. It feels like this only happens PAST 7 PM eastern, which is just a trend I've been noticing. I have hardwired internet 100 mbps connection speed, here are my speedtest.net results

Please help, I have Leatrix latency fix, i have have all my firewalls off, I've forwarded ALL the league of legends ports, ive done everything in my power to fix this, and the worst part is that it is ONLY HAPPENING on league of legends, I also play dota 2 , LATENCY is FINE, i play WoW Latency is Fine, Gw2 Latency is Fine, Diablo 3, Latency is FINE.

This has been happening for too long and its really effecting my game play, playing with a 2 second delay REALLY hurts sometimes and I have reinstalled the client 2 times, i have reset my router every night when this happens (no change) ive blocked every other user on my router except for myself, ive put my priority on my router for my IP to high, ive set my routers firewall OFF, ive done literally EVERYTHING, please post back with any suggestions

If it helps, i have verizon fios and a brand new PC, 4.6GhZ processor

My computer isn't as good as yours but I never had lag spikes prior to that patch.

I think it is on Riot's side, not yours.

I myself have been having serious lag issues all month constant attempting to reconnect and ping as high as 200. i pay for 100/meg service with my isp so i know it isent me. my games have become unplayable and 5 second delays on all my actions. it very sad that i put alot of money into this game only to have it lag all the time at this rate i might as well find a new game to like smite. thier in beta and i dont lag one bit kinda funny i guess once u make all the money u need u quit careing about fixing ur games at all

Just fyi - Leatrix Latency Fix works by removing the need for TCP connections to wait for acknowledgement of receival before sending another one. The LoL game data uses UDP traffic which doesn't wait for this by design so that won't help you for LoL. For other games like WoW it does however.

Thanks. still doesnt help my problem tho

it depends on where you live as well.

Imagine a circle. The ISP provider routers are all in the center of the circle.
Imagine you and your friend.
Your friend is 5miles away from the center, while you're 30miles away from the center.

The result is you'll have a bad connection compare to your friend.

You think you've been getting high ping?

PSHH.

My normal ping is 45-55. Look at this screenshot of my most recent game today. Other people in the game were complaining that they were suffering from high ping in recent games too.

Ah, here's my speedtests.

Riot seems to be ignoring the issue. My ping normally hovers around 60-90 and now I get all the way up to 300. this has never even been the case and I have been a player since March 2011

I've been playing since the beta this is ****ing frustrating
