Internet speed I recently upgraded to 1.5 from 750 with my ISP. However when I tested the speed it was still 750. I was told to change the MTU setting but it doesn't seem to change. Do you know the exact MTU it should be or is there another setting I need to change. Thanks, Shlomo [email protected]

The default size for MTU (Maximum Transmission Unit) works. Do not change it, unless your ISP tells you to do so.

What internet are u getting ? is it a DSL or a fiber connection or a Wifi ? and yes it is very good to have same UL/DL speed. but still what actually are u using and how much bandwidth . Thanks

There is no such thing as MTU For a cable ISP in routers !
However this error occur occur in gaming consoles mostly because there is something that is blocking the connection in the router .. Try the following Steps .. it might be helpful


You will have to open the following ports in your modem /router ( Contact your router manufacturer to do this )
Make sure the firewall is disabled in the Modem /Router
Make sure that UPnP is Enabled

Playstation Network Required Ports

TCP 80
TCP 443
TCP 5223
UDP 3478
UDP 3479
UDP 3658

You can use http://whatsmyip.org/ports/ to test if the ports are open.

Reduce the MTU settings on the router. You will need to open the set up page of the router. On the set up page , you will find the MTU set to Auto. Change it to manual and change the size to 1400. save the settings.
Also upgrade the firmware of the router.
Do you have any computer connected to the router ? If not then connect the computer to the router. download the firmware of the router.
Upgrade the firmware.
After upgrading the firmware , you will need to reset the router.
Once you reset the router, it will lose all the settings and you will need to reconfigure the router.

If you connect the computer to the modem, you are able to download the files.
But if you connect it through the router, it is not working.
the problem is with the router. Cogeco is a cable ISP.
you can reduce the MTU settings on the router. If MTU on the router is 1500 then Make it 1300.
Under security settings, disable the firewall on the router and disable the Block internet request.
If it doesn't work then try to upgrade the Firmware of the router.

MTU Adjustment

1. Access the web-based utility of the router.

a. Please open any web browser like Internet Explorer or Netscape Navigator.
b. Connect to the router by typing http://routerlogin.com/basicsetting.htm or http://192.168.1.1 in the address field and click Enter or Return key.
c. A window will prompt for a user name and password. The default username is "admin" and the default password is "password".

Note: If it does not take password as the password, you might have changed it when you have run the NETGEAR Setup CD so please try other passwords. If you cannot remember the password, you need to reset the router and run the Setup CD to reconfigure it.

2. Adjust the MTU setting.

a. Click on the WAN Setup under Advanced tab.
b. Lower down the MTU size to 1492, 1400, 1358 or 1300.
c. Click on the Apply button.

Note: You may verify from your ISP the recommended MTU size you can use.

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.

Try to access the router's setup page and change the MTU settings. The default address for the Befsr41 is 192.168.1.1. Here are instructions:

1) Use a computer wired to the router.
2) Launch a browser and type in 192.168.1.1, leave the username blank and the password is admin or the password you have set when you first configured the router.
3) Click on the Advanced tab then click on the Filters tab. On the bottom part you have MTU.
4) Enable that option and set MTU to 1500, 1400, 1300 (for cable ISP connection) and 1492 (for DSL connection) and check if it will work.
4) If that does not work, you can try upgrading the firmware of your router.

I personally have never known that changing the MTU setting can speed up your connection, as the MTU is the maximum transmition units that is sent to your pc from each web site and if the MTU setting is incorrect then some web sites will not load on your explorer page, the speed at which you download the page will not make any difference.

If you are supposed to get 20MB speed then you must be on cable and not ADSL as ADSL is a max of 8MB, so i would ring up Virgin or whoever and check the speed you should really be getting.

See these details posted on the netgear site, and you'll notice there is no mention of speed:-

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: How-To Configure Broadband Connections Using PPPoE.
• 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.

Have look in the router settings for the actual internet connection speeds, as these are a more true reading than the speed check as the speeds can vary at different times of the day and 2 or 3 speed checks can bring different results. your actual connection speed that is showing in the routers settings is the connection you are getting from your ISP. If you are with BT they usually recommend using their latest routers, why i'm not sure, as the only thing i have noted is that the MTU is set at 1500 (Maximum Transmition Units)and in other routers the MTU is automatically set at 1493, so look for the MTU setting and up it if necassary, but not above 1500, also double check all the settings, even put the bt router back in and see if speeds improve, if, you know the BT router is set up purposly for faster connection speeds. Also try checking your speed at a speed test site at a quieter time of day, you will also see different speed check sites give you different speed results.
