Sorry for late response I was helping run/shoutcasting a $3000 dota 2 trini tournament (sponsored by flow) over in the local dota group.Look out for nearby LoL events.
So you are having issues with league. . And it will be fixed eventually. For now however you have some options. These are the noted things that have worked thus far.
I will arrange based on threat level .
(Note if you are not tech savvy ask us to help. Remember we have a FLOW VIP GAMER TECH SUPPORT GROUP info below. ) Basic Lag and ping issues : Using wtfast
http://www.wtfast.com/promote.aspx?APID=2719(Choose League of Legends, choose a chicago or florida server for best results)
Minor connection issues ; Changing your DNS . You can use google dns or open dns. Some people have fixed all their issues doing this alone .
Major connections issues : Inability to login or load in after champ select
^ You need to use a decent vpn. Vyprvpn by golden frog works well but remember to turn off other programs is they will use up your free trial data.
Avast vpn also works well. 7 day premium free trial.
https://vyprvpn.com/refer?ar=2fsvbksgvc6nm_1 (use chicago server)
https://www.avast.com/en-us/secureline-vpn#pc (use Miami server)
^Also for some people logging in with avast is troublesome . If so start league of legends first, log in and then connect to avast.
https://www.hotspotshield.com/ is another vpn gaining some traction
(Thanks to Angelo Khan for suggesting )
