Transcript of NA Server Issues/Patterns and Fixes

192.64.171.
LoL Server and Hubs
After looking through 250+ logs my findings are clear.

The NA server consists of 4 main server hubs them being:
192.64.170.
192.64.171.
216.133.234.
64.7.194.
192.64.170.
216.133.234.
After the Riot's 'Network Configuration' a few days ago this hub has become less common and is relatively free of issues.
If a user is connecting to this hub they
can expect :
Low/Medium Ping Spikes
Some Stalls
Low/Medium Packet Lose
EDIT: This server is experiencing massive failures...WINMTR logs suggested that a ISP routing problem has arisen...
Connection gets dropped after a certain point.. 'Hop 9-12'
64.7.194.
This hub has been the 'best' hub and is considered free of issues.
If a user is connecting to this hub they
can expect :
Low/Medium Ping Spikes
No stalls
Low/Medium Packet Lose
Server Patterns
The NA server will automatically reroute a player to a different server hub after a maximum of 2 attempts with communicating
with a 'Faulty' hub. However, it will prioritize servers that are common over servers that are not. Eg the server registers high ping, many stalls or high packet lose it will retry that hub 1st Afterwards, it will reroute to a different hub but it will keep trying to connect to 'common' hubs even if it is still having issues...
NA Server Issues
I am not Riot Staff
Use 'Left/Right' arrows below to navigate please :)

This particular hub has had the most
issues and is the most common hub
at this current point in time.
If a user is connecting to this hub they
can expect :
High Ping Spikes
Multiple Stalls
High Packet Lose
This particular hub has had some
issues and is the second most
common hub.
If a user is connecting to this hub they
can expect :
Medium/High Ping Spikes
Multiple Stalls
Medium/High Packet Lose
How do you check which hub your connected to?
You can check which hub you connected to in your previous
game/s by going into the 'Network Logs'
Default path below:
C:\Riot Games\League of Legends\Logs\Network Logs

These logs pull information about which server hub
you are connected to and your ping, stalls and packet lose
Its just a bunch of numbers !!!
What does it mean??
Luckily the log has a key that tells you what all the numbers
mean:
[time], [address], [incoming], [outgoing], [app_ctos], [app_stoc], [loss], [sent], [ping], [variance], [reliable delayed], [unreliable delayed], [app update delayed], [Time spent in critical section (frame)]

The numbers that are most important ones
are
[address]
,
[loss]
and
[ping]
.

Note, that a 'stall' is when you feel that champs are
'teleporting around', 'minions aren't dying' and 'delay on actions'.
Example
Please Note that I am not Riot Staff this is how things 'look' from Me and my testers viewpoint. Unfortunately, this software doesn't allow HTTP links so just google the links yourself.
Riot Morgageddon popped into the thread and has requested MTR logs for all recent server IP's. Please use the netlogs to find out which IP's to test using WINMTR and test the last 10 at least also attach those last 10 netlogs
to a forum post. In a post also state when issues started to occur and what you have tried to resolves them i.e the 'Phases' which will be discussed later.
If you haven't already submit a 'Support Ticket' with this information as well as he just suggested on the Forums.
Link to software: http://winmtr.net/
Riot Morgageddon
"If you see packet loss, abnormally high ping between nodes, or anything suspicious that's not directly at the last IP, it's an issue with routing between the ISPs, which I think is the likely cause of these issues.

If it's not, then this will help our network engineers to look at the base servers if we're having missing data there."

Server issues or ISP issues doesn't matter which run the tests regardless.

This will tell you how to interpret the WINMTR Logs

His Quote
The 'Phase' Fixes
For some testers the 'Phase Fixes' have decreased issues by 80-90% some even having strings of 'good games' with little issues... the fixes can't resolve ISP or Server Issues tho.
There, is no guarantee that issues will improve after doing the Phases but your welcome to try.

Phase 1
Ensure that you have essential programs and feature for running LoL installed and that they are working normally
Install ALL
Windows Updates
Some times not having Windows up to date can cause many issues with LoL. Please check for any updates, even optional ones, and install them all.

See Microsoft Help for instructions
http://windows.microsoft.com/en-au/windows-vista/install-windows-updates
Install/Repair
.NET Framework
.NET Framework is essential for things to run smoothly with LoL. If you have 3.5, 4.0 and 4.5 installed already repair them as the installation may be corrupted.

Link: http://www.microsoft.com/en-au/download/details.aspx?id=30653
Install Direct X Runtime
Direct X Runtime is essential for things to run smoothly with LoL. A corrupt version is commonly the cause of Graphical Glitches and FPS Drops, however try installing/repairing it anyways.


Link: http://www.microsoft.com/en-au/download/details.aspx?id=35
Phase 2
Uninstall conflicting or malicious software and LoL Part Programs
Uninstall ALL versions of Internet Explorer or Update IT
Internet Explorer has caused multiple issues with LoL in the past so its best to simply remove it. Consider a different Internet Browser like Firefox or Google Chrome.

Google:"Uninstalling All versions of
Internet Explorer" for instructions.
Alternatively you can Update it
Uninstall LoL Replay and LoL Matches
These part programs are simply malicious and can interfere with signals. If you are having a lot of crashes on loading screen Completely Uninstall these programs and any other part programs from your computer.

Link: http://windows.microsoft.com/en-au/windows/uninstall-change-program#uninstall-change-program=windows-7
Uninstall 'Custom Skin Creators'
Again another part program so it's best to uninstall it. In general LoL Part Programs are malicious.
Phase 3
TRY rerouting connection through a VPN like HotSpotShield (HSS).
In some cases it has improved issues in others it has complicated them.
Don't get tricked into buying the
'Elite Version' of HSS..
They might try to scam you.
Phase 4
Try the '8 things'

http://forums.na.leagueoflegends.com/board/showthread.php?t=3043730

Try as many as these as possible and see if it helps it has for some...
Phase 5
Update drivers for
network devices and install
its latest firmware if any
exists
Update drivers for
'Network Adapters'
Update drivers for
'Video Cards'
Update your hardware Router/Modem with the latest Firmware
Update your Video Card Drivers ~ Method below (Or do it from the manufacturers site)
--> Windows Key and Search for 'Device Manager' in the search bar
--> Click on the 'Device Manager' Application
--> Click on the sideways triangle to the left of 'Display Adapters'
--> Find and right click on your video card or do the following for all display adapters
--> In the Context Menu select 'Update Driver Software'
--> In this menu (make sure you have internet connection) click on 'Search Automatically for Updated Driver Software'
--> Follow the remaining dialogues if you need to update your video card driver
--> Restart your computer
Instructions
Update your Network Adapter Drivers ~ Method below (Or do it from the manufacturers site)
--> Windows Key and Search for 'Device Manager' in the search bar
--> Click on the 'Device Manager' Application
--> Click on the sideways triangle to the left of 'Network Adapters'
--> Find and right click on your network card or do the following for all network adapters
--> In the Context Menu select 'Update Driver Software'
--> In this menu (make sure you have internet connection) click on 'Search Automatically for Updated Driver Software'
--> Follow the remaining dialogues if you need to update your network adapter driver
--> Restart your computer
Instructions
I noticed in recent days that some modem/routers have manufacturers firmware updates that may resolve issues, although its untested you willing to google your devices model number and get the latest firmware.
Hardware Firmware
Reserved for more fixes.
Phase 6
Phase 7
Reconfiguring Modem/Router settings and resetting the signal path.
If your not sure about things Google your hardware model number.
Adding Firewall Exceptions
You will need admin rights to your hardware. If you are on a secure network and you have a Hardware Firewall please make sure that ALL server IP and hub variants (Over 1250 of them for NA servers) are listed as EXCEPTIONS and/or Trusted Connections. Link: https://support.leagueoflegends.com/entries/20749152-Server-IP-Addresses
"NA Complete Ranges"
Disabling Hardware Firewalls
If your not worried about not having hardware firewall simply disable them... (Google how to)
Wiping DNS Cache and Resetting devices
Some modems/router Cache DNS requests for further inquiry if yours' does wipe the cache clean in an attempt to make the LoL server 'forget' about you and reset rerouting patterns.
Resetting Hardware Devices
Sometime Hardware devices get overstressed and they misfire connections. Simply turn off both your Modem/Router for 5-10 min at the power point and then turn them back on again. Continue to the next step.
Restart Computer and 'Flush DNS'
After resetting modem/router restart your computer and afterwards run a 'Flush DNS' command prompt command . This will make the server reset rerouting if your 'stuck on a bad path'. Only do it once or twice not after every game.
