The router in use may not support IP fragments, and the communication features of some games may be restricted?

9 replies 20584 views Edited Jul 23, 2011

Help, I use a modem and a router and i get this message on my ps3, I have tried many thing to get this message off so i can get NAT type 2 on my ps3. If a router does not support ip fragments, does that mean im stuck with NAT type 3 forever???

Please reply. I need help.

The IP fragments message means your MTU setting in your router is not correct. Insure the MTU setting on your PS3 is set to automatic and try to locate the MTU value in your router pages and note what it is. If it's 1500 it may need to be lower.

Go to this web site

http://help.expedient.com/broadband/mtu_ping_test.shtml

It will assist you in determining your correct MTU value.

Also, what make router is it?

i did find this while searching the message you put in. some said it helped - others said it didnt - you may want to try it

ok thanks, yea i think thats true, it only affects some games. I play cod online all the time with ease at finding games, but then i go on my assassins creed brotherhood and i can hardly ever find a match. my friend has NAT type 2 and he finds matches almost instantly every time.

Hey found the same issue with my service, Time warner cable, Ambit router/modem. I found a small program that automatically detects the best MTU for you without all the guess work. You can find it at http://qsextreme.com/mtutest/

My max MTU that doesn't fragment is 1024. Since I've changed it on my pc, router and in the network setup on my PS3 I've noticed that I can connect to online games and find more servers instantly. I still get the Router in use may not support IP fragments..... message but I've noticed a huge difference. Hope this helps
