MTU: Helping to quicken your gameplay!

• shadowbuddy8 wrote on 2010-06-07 22:41
  i has teh solution.
  
  go to command prompt and type ipconfig /all
  look for something like (for wireless) ethernet adapter.... or Wireless LAN adapter.......
  whatever it says after that insert into your (netsh interface ipv4 set subinterface "Local Area Connection" mtu=xxxx store=persistent) string where it says local internet connection. for me it said Wireless LAN adapter Wireless Network Connection 2 so i put "Wireless Network Connection 2" in instead of just "Wireless Network Connection"

  btw, i didnt need to get a static IP either. i just set the MTU value and it worked

  Setting your Router MTU will damage your connection to the point where all other things become nearly useless.
  This is a fact and not an opinion.
  Why people want a lower MTU for lag purposes i cannot understand. My ping is 80-100 MS to the server and my MTU is set to the maximum of 1500 and i lag LESS than a resident in LA.
  And i live with a crappy internet connection that likes to bail on me and screw me over and i live in Wisconsin.
  Why you want to damage your internet for a game online... Mind boggling. That is my two cents. Heed them or choose to lower your MTU.
  
  TL;DR
  My name is Aubog007 and i am AGAINST MTU change.

  I kind of agree with Aubog, there's only a few differences and there are disadvantages too. You're more sensitive to server lag and that may cause you to D/C at times. What's annoying about it is that it will decrease your throughput so if you're going to download something while AFK on Mabi, you'll notice slower download speeds. Also there are times when summoning a pet takes a while and I noticed this a few times and thought my client frozed. I was still getting hit and could do nothing about it because the pet summoning message was still there. Overall, it's good for people that may lag a lot and this is their last resort. If you rarely lag at all, you don't really have to do this.

  Does the default "1500" value apply to all OS, namely XP?

  Ping of 80-100 is prety good,try playing with 250-300MS.Besides you can just change it back to 1500 after playing mabi,it only takes 10 seconds to chage it back,so i dont see whats the problem with changing the MTU.

  And, you can just make batch files to make it easier to switch back and forth between MTU settings. I have files for 128, 368, and 1500. Also, it isn't really even meant for really laggy people(imo). I find it better suited for people who base their gameplay around fast-paced combos, such as dueling and PvP. If you spam skills with a lower MTU, it is significantly faster than with default(1500). Plus, changing your MTU on your router doesn't really do much. It is basically the same as changing MTU through cmd or through the registry. It just fks up your connection more and creates the risk of not being able to return to the router page to reset your MTU.

  Bump since I added videos to really show how much of a difference a lower MTU could make. The connection I have is 30 megabit download by the way, so it doesn't just help low end internet connection users.

  I have my MTU at 386 and the only problem I have is that my download speed lowers a bit. But it's super easy to change back so it doesn't matter.

  It's easier if you make batch files to automate the change too.

  For easy MTU changing.
  
  As mentioned, it'll lower your throughput but for online gaming it can make a fairly substantial difference though it won't work for everyone. Some people won't see any difference between 1500 or 500.

  Type the command out in a new notepad file, and then when you save the file, change the save as part or w/e to "All Files". Put whatever.bat into the file name, and save it to wherever and it should be a batch file. Run them as administrator or they won't work though.

  MTU, or Maximum Transmission Unit, is the max amount of bytes you can accumulate before a packet of data is sent(?). Often, it helps your ping in an MMO decrease a lot due to you being able to send packets much quicker. This combined with disabling the Nagle Algorithm makes for an amazing lag killer.
  
  Honestly, this lag fix is often overlooked by many people. To me, it is VERY easy to do, and can be easily set back to factory default.
  
  Step 1) Run cmd.exe as an administrator.
  
  Step 2) type the command: netsh interface ipv4 set subinterface "Local Area Connection" mtu=xxxx store=persistent
  
  Note: If you use a wireless connection, you would type "Wireless Network Connection" rather than "Local ---"
  Note2: The value of the MTU can be anywhere from 48 to 1500(default value). Lower values decrease load time of content heavy pages and games, so a mid-range value is probably best. Also, the value of the MTU has to be a multiple of 4(?). (I set my MTU usually to 168, but 368 is a popular choice also. Content heavy games such as Aion would probably need an MTU of around 568 or so, etc. Whatever floats your boat, haha.)
  
  Step 3) Hit enter...(lol)
  
  If all goes well your MTU should have been changed. This method is only confirmed for Vista OS though, but it wouldn't hurt to try it with a different Windows OS.
  
  Kind criticism is appreciated, but don't flame meeeee D:
  
  Extra IMPORTANT-ish note! Please have a static IP address before trying to change your MTU to anything besides 1500. [GUIDE TO STATIC IP]

  If nothing works, I can try a TeamViewer session with you. This is a COMPLETE last resort though.
  
  
  Windows XP users:
  
  Step 1) Run Regedit
  
  Step 2) Browse to HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\Tcpip\Parameter s\Interfaces\
  
  Step 3) Similar to how you would disable Nagle, locate the folder which has info about your IP address
  
  Step 4) Within that folder, there might be a value named MTU. If there isn't, create a d-word value named MTU. Modify that value and change the number to what please you. You can use Hex:MTU ratio examples that I found such as 96:150, 146:326, and 500:1280
  
  Step 5) Reboot your computer and if a noticeable change is present, you probably changed your MTU! Congrats!

  You have to relog in mabi if you didn't. Trying to restart your system might change it too.
