High ping and packet's loss EUNE

Hello guys :)
I'm writing to you, becouse I have problem with lags on EUNE.
With wtfast was ok, but now it's not free, so I'm looking for some program like wtfast or tip how to stop packet's loss on server(on west is ok, but I have my main acc on eune + my friends play there).
I hope you can help me.
Greetings :)

Try to repair the client first, also run the game as administrator. If this doesn't help, please reinstall the game.

Unfortunately I don't think that this is a client issue. It could be a problem on Riots side, but I can't tell it exactly, because I've never played on EUNE.

Solution!

Thank you, but repairing client didn't help.
Do you know guys something like wtfast, but free?

I got the same issue, this started around 24 hours ago, it's hard to play now the ping is stuck on double what it has been before, I tried logging on EUW and NA and the ping is just fine, I don't really know what RIOT did to EUNE.

btw, I tried something that fixed the ping for around 3 hours then it stopped working, try using a vpn.
