Corris Veteran Posted December 21, 2008 Veteran Share Posted December 21, 2008 So to start, I know N and the whole draft business, and I didn't know at the time of purchase back in January either, it was a quick not really thinking purchase, I just needed a wireless router at the time. If this doesn't work out well, I am most probably just going to buy a new one in Jan. I also figured it was better asking in here since it seems to be more of a router problem than a Ps3 problem from what I can tell. Anyway, I have been having these problems for a few months, and I don't know why. After setting up the Ps3 and the N router, during a test I got "Your router may not support IP-fragments and communication features of some games may be restricted" Now I didn't know why, so I tinkered around a bit. I updated to the latest firmware, which I had to download myself as it wasn't being found by the router, I gave the Ps3 a static IP and set the same IP to the DMZ on the router which should sort out any port problems and connects all fine in every aspect besides the message still appears, and its quite annoying. I'm with Virgin Media if that helps. Apparently it might have something to do with the MTU size or something, but I can't seem to find any such field in any of the router options. Any help would be appreciated. Link to comment https://www.neowin.net/forum/topic/712014-belkin-n-wireless-ps3-problems/ Share on other sites More sharing options...
+BudMan MVC Posted December 21, 2008 MVC Share Posted December 21, 2008 What do you have the MTU set on your PS3? It should be automatic. Alos what is the model number of your belkin router? What MTU is it set too? You should contact your ISP on what MTU setting your router should be at.

The Ps3 is set to Automatic. The model number for the router is F5D8233-4v3, and it says version 3001uk, which I assume is the preloaded firmware. I don't know what the routers MTU is set to, I can't find it anywhere. But according to numerous websites the Virgin Media cable connection should be 1500.

Jeremy Kyle Posted December 21, 2008 Share Posted December 21, 2008 The MTU is fine for Virgin Media, I know that much. I unfortunately don't know that router so can't help you find the MTU. Does the router homepage have a help/search facility?

+BudMan MVC Posted December 21, 2008 MVC Share Posted December 21, 2008 Well If its the UK model, I show the latest firmware being http://www.belkin.com/uk/support/article/?...0288&scid=0 9/25/08 3.01.29 What is the make and model of your "modem" Its possible this is doing NAT as well and not just a modem? You do not have any other devices between your ps3 and the internet? The manual shows you can change the MTU when using PPPoE Maybe this router does not default to 1500? I would check this setting, can not hurt to change it.. If it does - just put it back ;) Link to comment https://www.neowin.net/forum/topic/712014-belkin-n-wireless-ps3-problems/#findComment-590298238 Share on other sites More sharing options...
Jeremy Kyle Posted December 21, 2008 Share Posted December 21, 2008 It's probably the standard Virgin Media modem he is using, so it won't be running NAT.

I found the menu in the PPPoE setting, which is where I hadn't looked since I use the dynamic connection and there are no settings when selected. I set it to 1500, and tested the connection and I didn't get the IP fragments message, at least not at first, but it appeared a bit afterwards, I think on my third test and stayed then. So I tried 1492, since I saw that mentioned somewhere, and that seems to be working better, but maybe its in my head, my friends list loads up pretty quickly now, faster than before form memory, but after a few tests through using it the issue is still there and the message has returned. As to the modem, its just an NTL modem we have had for ages. It says ntl home:200 on the bottom.

+BudMan MVC Posted December 22, 2008 MVC Share Posted December 22, 2008 Well if your hitting somwhere down the line that needs a smaller packet size, then you would need to lower the MTU not increase it. Try lowering it vs making it bigger. Was it set at 1454 like in the manual? Im not sure that setting has any effect anyway -- your not using PPPoE. Vs leaving it as auto on the PS3, lower it there to match what setting your using on the router. To find what MTU is required to get to a location without fragmentation, just do a ping -f -l size host example C:\>ping -f -l 1474 www.neowin.net Pinging neowin.net [209.124.63.219] with 1474 bytes of data: Packet needs to be fragmented but DF set. Packet needs to be fragmented but DF set. Packet needs to be fragmented but DF set. I used 1474 just to get the error you might see, that is too big.. Since you have to add 28 to the size in your overheard to find your maxmtu. As you can see if I ping it with 1472 +28 = 1500 C:\>ping -f -l 1472 www.neowin.net Pinging neowin.net [209.124.63.219] with 1472 bytes of data: Reply from 209.124.63.219: bytes=1472 time=42ms TTL=45 Reply from 209.124.63.219: bytes=1472 time=42ms TTL=45 You would want to ping the location your wanting to go to find the maxmtu to that location. Do you know the IP of where you test too? But it might just be that the Auto setting on the PS3 doesn't work quite right since your behind a NAT, and your local network MTU would be higher than external. Try lowering it on the PS3 to see if you can make the error go away. Here is some info on what the MTU is http://en.wikipedia.org/wiki/Maximum_transmission_unit edit: also you never stated, I just assumed your wired from the ps3 to the router -- are you wireless?

Corris Veteran Posted December 22, 2008 Author Veteran Share Posted December 22, 2008 To start I am wireless, the modem and router are downstairs, and the Ps3 is upstairs in my room, and signal strength is always high. And I pinged Neowin since I don't know about the location or IP that is tested too, as whatever it is seems to be a problem between the router and the Ps3. so I pinged Neowin and 1472 was the highest it was going to, so using what you said my MTU should be 1500. And the Ps3 has been set to Automatic detect the MTU and I have also set it to use 1500, problem is still there either way. And I doubt whatever is the Ps3's fault, a few times a year me and friends go to a house in the middle of no where, and it works perfectly there. Though that is with Sky and a Sky supplied router. Could it just be that the router doesn't support IP Fragments or something, though randomly assuming I would guess this is whole this sin't new and should be in every router anyway? Though telling you its wireless could mean its something else though? And thanks for helping so far, your the only one who has given any advice. :D Link to comment https://www.neowin.net/forum/topic/712014-belkin-n-wireless-ps3-problems/#findComment-590304020 Share on other sites More sharing options...
+BudMan MVC Posted December 23, 2008 MVC Share Posted December 23, 2008 I thought I was pretty clear on the having to go down in size.. Going to neowin is not really a valid test of the MTU size to where you would be going when you test your ps3 or when playing its games. But setting your PS3 to manual 1500 or Auto is not a very good test. I only used neowin as an example, so I could show you the error, etc. I would suggest you LOWER it on the PS3... Go as low as it will go, and then go up from there. Or just drop it to 1492 or 1472, if those do not work then try the lowest setting, if the error is gone -- then you can go up from there.

Corris Veteran Posted December 23, 2008 Author Veteran Share Posted December 23, 2008 The lowest it will go on the Ps3 is 576. That still produced the ip fragment error, so going higher wont help? but I tried a couple different ones and it was the same. Setting it back to automatic made the error disappear for about 2 minutes, then returned.

+BudMan MVC Posted December 23, 2008 MVC Share Posted December 23, 2008 Well if your getting it on 576 I would say its bogus error, and something else is causing it. I would suggest trying it wired to your router, if still has problems then connect it directly to the modem, take the router out of the picture. When you connect it to the modem, you would have to reboot the modem once you connected the ps3 vs your router.

Ineedaname Posted January 13, 2009 Share Posted January 13, 2009 Having had this problem and having another I was looking for a solution to my other problem and stumbled on this. The simple solution is to add your PS3 to the DMZ and it makes the NAT type down to 2 making it work without the problems =) Link to comment https://www.neowin.net/forum/topic/712014-belkin-n-wireless-ps3-problems/#findComment-590414664 Share on other sites More sharing options...
Vhero Posted May 11, 2009 Share Posted May 11, 2009 I too have this router and went to pppoe page but it wont let me change the MTU value as I need a name and password?? I have had nothing but problems with this router and wouldn't advise it to any ps3 owner.

Just so you know, back when this thread was made I do not even think Corris was even on staff yet. Also because of the abrupt way it ended, with no resolution, I do not think it is a matter of no one wants to help you, I think it is a matter of no one ever figured out what the problem was. My point being if someone can help you here they indeed will, has nothing to do with being staff or post count.
