The dsl is red and when it turn green i still can connect to xbox live, but when i try to connect my xbox says i need a higher mtu is that possible to change from a laptop

Once you have all the wireless settings of the router, you are ready to connect the play station or the x-box to the wireless network.


On the x-box you will need to connect to the wireless network now.
Open the main Interface of the X-Box.

1. In the Xbox Dashboard, go to My Xbox and open System Settings.

2. Select Network Settings, Configure Network.

3. On the Basic Settings tab, select your wireless settings.

4. Select the name (SSID) of your wireless network. If your router isn't broadcasting your network's name, select Specify Unlisted Network and enter the name.

5. If your network has wireless security, enter your WEP or WPA key.

6. Try to connect to Xbox LIVE again.

Trouble connecting to the internet on X-box ,Play station or WII ?

You can try to reduce the MTU settings on the router. if the MTU on the router is set to 1500 then change the MTU to 1365. Also you will need to open the ports on the router.

For X-box port numbers are - 53, 80-88, 3074 .

I have a 2Wire modem and i need to Change my Mtu settings how will i do this?

A computer's MTU or maximum transmission unit is a measure of the amount of data that can be sent over a specific network protocol at one time. Because the various network protocols on your computer all have to communicate with one another the MTU of your system can have detrimental effects if improperly set. The MTU most often referenced when talking about PCs is the TCPIP MTU. This is the MTU value used for all internet communication on your computer.
  1. tep 1 Launch DrTCP and select the proper network adapter from the "Adapter Settings" pull down list box at the bottom of the program. The adapter you choose should be the one physically connected to your modem or router for internet accessmag-glass_10x10.gif via an ethernet cable. You can find proper hardware name of the adaptor by going to the windows control panel and clicking on "Network Places" to see which adaptor handles your internet connection.
  2. Step 2 Enter a numerical value between 1400 and 1500 in the text box labeled "MTU". This numerical value is transmitted to every remote server you request data from to be used as a common size of data to be sent with every packet of data sent to your computer. It is advised you start at 1500 and move down in increments of 10 until a satisfactory result is found. Usually MTU problems are not a result of your hardware or the remote server. The problem almost always is ISP hardware not supporting frames as large as you and the remote server have agreed upon sending. Lowering your MTU value in increments allows you to find the largest size possible without having packets dropped due to being too large.
  3. Step 3 Click "Save" and exit the program by clicking "Exit" or clicking the "X" button in the upper right corner of the windowsmag-glass_10x10.gif form.
  4. Step 4 Restart your computer for the changes to take effect and check to see if the changed MTU has increased system network performance. This process of trial and error may require several attempts to find a setting that is optimal depending on your specific network configuration. If you are unable to find an MTU setting that works a quick call to your ISP to ask what their recommended MTU setting should resolve things.

It is possible that my router is blocking some sites

It is quite possible. You may have to access the user interface of your 2wire 1800 gh and then enable secured site access. You may have to open port 443 or lower your MTU to about 1400 or 1300. Please PM if you need further information

Log on to the routers interface and look for MTU size. Once you get there, reduce it to 1492. This will help.

Router blocks MSN and https: secure sites

I had exactly the same problem. Check your mtu settings on the 2wire. I think the modem is set at 1450 (or there abouts) An article (sorry can't find a link) suggested raising it to 1500 this didnt work for me so I started reducing it instead. Once i set it at 1400 mtu I was able to log on to secure sites again. Hope this helps.
