If you're getting server status undefined when the servers are up (they're up right now) what's happening is your game client is trying to send a request to the servers to check on their status but isn't able to get a reply.

This means that something on your local network or connection is completely cutting you off from LoL.

Most often this is a firewall or antivirus program. If that's not it for you, you'll need to figure out what else on your connection is causing the issue.

bump.../sigh

Same problem.

RADS couldn't connect....I tried all of the solutions. Even reinstalled twice. Can we actually get some answers, Riot?

Yep, same problem. Just started happening today. I'm considering a system restore and if that doesn't work I am gonna have to dig deep into my modem's/router's/computer's firewalls and see what is there. Funny thing is, not even Battlelog for Battlefield 3 is loading but every other page does.

SAME PROBLEM

and I seriously doubt it's local, since I disabled my firewall completely, fully updated windows, reinstalled the game, etc. ...and my girlfriend has the same problem. I played this morning and did nothing on my computer in between. WTF

having the same problem in installing zed patch,
stuck with rads.dll

yep, same condition
3 times reinstalled, fully updated windows, firewall no problem, turned off antivirus, 300+ hdd

but still, stuck with rads.dll

used the solutions provided by riot but still doesn't work

1. get the file reds_user_kernel.exe from a friend (it doesnt let me upload the file) the file can the found in computer/local disk/riot games/league of legends/RADS/system
2. put it in computer/local disk/riot games/league of legends/RADS/system
it will fix your problem (it fixed mine)
3. launch lol

***important: make sure that lol is close enen the processes

GOOD LUCK!!!
