FOr over half a year, I have had problems with dc'ing in league. It is not, in any way, my fault, since every time it happens, only league dc's, but everything else works. It is not my computer either, I have had it sent to the manufacturer 3 times to be checked, and it comes back with no problems. I have reinstalled countless times, and repaired the client too. I have been asking for help everywhere, but Riot keeps ignoring me. Then I get banned when I try to play, though it is not my fault at all. I have just been banned for a week again. It seems as if Riot only likes to punish, not help. Plsplspls can someone respond to this post. I am getting sick and tired of this, and I am about to quit if no one helps me with this issue. Don't let me lose hope in you Riot. Pls help.
I have not seen this issue. Often there are router or modem settings that may interfere with connections to certain providers, and this is not at all the service provider's fault. Check for NAT redirection, and disable it. This causes many issues with internet gaming. Disable 'Filter Multicast' if this is an option. This can limit communications and cause connections to specific services to drop randomly. Also check

This is a great resource to help set up port forwarding.
Take a calm and collected approach to your troubleshooting issues, and you will find an effective resolution.
You should get banned if you haven't taken the measures required as set forth by RIOT

Some routers also have a DMZ option. While this is a great way to resolve many connection issues, it is not suggested as it makes your computer a beacon to hackers lurking on the net.
Port forwarding is a safer option as it only opens the ports that RIOT relies on.
Read closely the part where it says,"Each of these ports must be forwarded for League of Legends to operate properly."
Don't do just a part of the instructions, then freak out if it doesn't work.
