Why do you want to change the mtu value? That setting will be standardised and auto set on the setup when you connect to your internet provider, kit should only be changed if they have said it needs to be changed. Changing it can result in loss of connection and data errors while connected.

To reset the D-Link back to the default settings, press and hold the RESET button on the back of the router and power up the router, hold the RESET button for 5 secs until the LEDs flash at the same time then release the RESET button.
The default login = admin
The default PW = blank (just press Enter)

360 mtu test keeps failing


Access the routers setup page by typing 192.168.1.1 (ip address of the router) on the address bar on IE.

then on basic setup page at the bottom part of the page you will see MTU normally its on auto,
to change the value set it to manual. ask your isp what is their prefferred value for the mtu you can go as high as 1300 to 1500.

Needs to know more about MTU size changes


Changing the MTU size to any "small" value is a bad idea -- compare it to running to the corner store every time that you need to take anything (milk, ice-cube) out of your refrigerator -- the "time" to go back-and-forth to the store (or the Internet) will be excessive, and "slow" down your productivity.

Tell your son to change the MTU settings on the router, especially if you have DSL.

Changing MTU on router

Step 1.
Log into your router by open your Internet browser (e.g. Internet Explorer), enter the IP address of your router (e.g. 192.168.0.1) and press Enter. Specify username (admin) and password to log into the router.

Step 2. Click on the Home tab and click on WAN on the left side.

Step 3. Look for the MTU field (note that it may not be available in some router models). The default MTU value is 1500, change it to lower number, e.g. 1200.

Step 4. Test your ability to connect to those specific sites youre having trouble with. If changing the MTU rate to 1200 does not resolve the problem, start lowering it in increments of ten until the problem is resolved (you may need to go as low as 600 depending on your DSL connection).
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

First I will need to know the type of ISP service you have, T1 - DSL - ADSL - CABLE - etc. And the connection type, STATIC IP - DYNAMIC IP - PPPOE - etc. BPCS

MTU


MTU, Partial Loss of Internet Connection, and Performance MTU (Maximum Transmission Unit) is the largest packet a network device transmits. The best MTU setting for NETGEAR equipment is often just the default value. MTU is sometimes presented as something that can be easily changed to improve performance, but in practice this may cause problems. Leave MTU unchanged unless one of these situations applies: 1. You have problems connecting to your ISP or other Internet service, and their technical support (or NETGEAR's) recommends changing MTU. For example, these services may require an MTU change: * Yahoo email * MSN * AOL's DSL service 2. You use VPN, and have severe performance problems. 3. You used a program to "optimize" MTU for performance reasons, and now you have connectivity or performance problems. * An easy solution to most problems is to change MTU to 1400. * If you are willing to experiment, gradually reduce MTU as described in "Details of MTU", below. How to Change a Computer's MTU Size Note: If you change MTU on one computer, it is likely you will want to change it on your other computers, switches, and routers, as well. Instructions for changing MTU on other NETGEAR devices is found in the Reference Manuals. The third party Dr. TCP software can be used to change the MTU setting. 1. Download it from this link, choosing the zip file or the exe file at the top of the page. 2. Run the utility. 3. In the Adapter Settings pull down, select the Ethernet driver and adapter used to connect with the network. 4. In the MTU box, type the MTU size you are trying. 5. Click in any other box, without changing the data there. 6. Click Save. 7. Click Exit. 8. Restart the computer. Details About MTU A packet sent to a device larger than its MTU is broken into pieces. Ideally, MTU would be set to the same ? large ? value on all your computers, routers and switches, as well as on all the parts of the Internet that you access. But you cannot control the MTU on the Internet, and in practice the optimum MTU size on your LAN is related to your hardware, software, wireless interference, etc. * Tweaking MTU size may work well in one situation, but cause performance and connection problems in others. * When network devices with different MTU settings communicate, packets are fragmented to accommodate the one with the smallest MTU. * Windows XP sets MTU automatically, that is, it optimizes computer MTU for you. This Microsoft article explains resolving lack of connection to a broadband ISP using Windows XP: http://www.microsoft.com/windowsxp/using/networking/learnmore/ppoe.mspx * Once a network device fragments a packet, the data stays fragmented until arriving at the destination computer. Setting MTU size is a process of trial-and-error: start with the maximum value of 1500, then reduce the size until the problem goes away. Using one of these values is likely to solve problems caused by MTU size: * 1500. The largest Ethernet packet size; it is also the default value. This is the typical setting for non-PPPoE, non-VPN connections. The default value for NETGEAR routers, adapters and switches. * 1492. The size PPPoE prefers. * 1472. Maximum size to use for pinging. (Bigger packets are fragmented.) * 1468. The size DHCP prefers. * 1460. Usable by AOL if you don't have large email attachments, etc. * 1430. The size VPN and PPTP prefer. * 1400. Maximum size for AOL DSL. * 576. Typical value to connect to dial-up ISPs.
