XBOX LIVE FAILED: insufficient MTU value . . . though mine is set at 1492 . . . hmm

Hey Xboys,

Firstly any help is greatly appreciated. Thank you.

Here is some info to help you help me . . .


- I live in Sydney, Australia

- My modem/router brand & model number is NETGEAR Wireless-N ADSL2+ Modem Router Model DGN2000

- Network Connection Type: Wireless with the black two antenna external Xbox Wireless Network Adapter

- My wireless encryption type is WEP (keeping it simple)

- UPnP is Enabled

- For NAT and TCP/UPN stuff . . . my routers firewall settings are roughly this . . . Outbound nothings blocked . . . but inbound is block always . . . this might be the problem i don't understand port forwarding as much as I should . . . or really much at all . . .

- The error code I keep getting is the your MTU value is not high enough . . . however my MTU value is set to 1492 . . . which is all good in the hood . . . so its not that . . .

I have ADSL2+ Broadband internet . . . and im pretty far from the tower so its not as fast as it could be . . .

My internet service provider is TPG . . . nice and cheap and slow . . .


I've been able to download updates and it notifies me of my online friends but when I test the xbox live connection it gives me the TEST FAILED . . . your network doesn't have a suffiecient MTU setting. Xbox LIVE requires a minimum MTU setting of 1364 . . . .

I have also just gone over my download limit so my internet is a bit slow . . .

I also can't connect my laptop to xbox to play movies through vuze or connect360 . . .

any help would be great thank you for your time

If your MTU setting is set correctly, but you're not getting a sufficient MTU value, then it may be your ISP causing the problem. Can you contact them and see if they can help?

I can connect by connecting my xbox straight to my modem . . . and i can also use vuze through that . . . which means it's probably something to do with my wireless router setting . . .

Try setting your MTU on the router to 1364. High isn't always better. Do you have a Smart Phone? Or PC with a WiFi card. You may want to run a WiFi analyzer to see what wireless networks are available around your area. You may have to switch your routers channel to one that's not in use or as heavily used. Since you're able to connect to Live when using the routers Ethernet ports I suspect you may be on a channel that's over loaded. If you set your MTU too high and your wireless network is unable to transmit packets that large without lots of drops and fragmentation you will run into issues.

1. I would try and download a WiFi analyzer on your Smartphone or PC and see what channels all the wifi networks around you are using. Find a channel that's not heavily used and switch your router to that channel. Try testing again.

2. Lower your MTU to 1364 if your unable to connect on a different channel. If you have success then you can try raising the MTU (personally I would just leave it at 1364 if it's working)

I've read mixer reviews on this router. If possible you may want to return it for a different make if you continue to have issues.

I know this isn't relevant and nor am I female but that is kind of sexists (On the first line);

Unfortunately you don't have PM(s) on therefore I'm can't say nothing however please modify the first line.

It's just since these forums are for both genders and you are addressing just one gender.

My friend had this problem, all we had to do was move the Xbox console closer to the router and it fixed itself.
