Changing the MTU size in Mac OS X 10

Sometimes a computer may struggle to reliably receive and transmit data - resulting in slow speeds or interrupted access to some sites and Internet services. Altering the MTU size can help resolve these problems. This guide shows you how for Mac OS X versions 10.6, 10.7, 10.8 and 10.9. Setting the MTU Size: Click the Apple menu icon To set the best MTU value and optimize Internet speed, please perform the following steps: 1 Open Terminal. 2 Type the command below and hit enter.. ping -c 3 -D -s 1500 google.com . If the reply you get is ping: sendto: Message too long, then you have to try a lower MTU value.Keep decreasing the value by 10, i.e. 1490, 1480, 1470 until you get a successful reply

Fix WiFi on OS X by tweaking the MTU // A fractal spectrum

Le MTU est un paramètre de vos interfaces réseaux qui définit la taille des paquets. Selon le mode de connexion, notamment si vous utilisez un VPN, vous pouvez être amené à réduire le MTU. En effet, les VPN apportent une surcouche et réduire le MTU peut aider à rendre la connexion plus fluide Helpful hint: One way to verify whether if it is an MTU problem is to try and access the application or website via dial up access.Since dial up uses a default MTU of 576 bytes you will not have the same problems as broadband. If you have problems with both broadband and dial up access then the problem is probably something else

L'unité de transmission maximale (MTU) est le plus grand paquet transmis par un périphérique réseau. Pour un équipement NETGEAR, il est souvent recommandé de configurer la MTU sur la valeur par défaut. La MTU est parfois présentée comme une valeur facilement modifiable afin d'améliorer les performances On my WiFi AP, I can set the RTS threshold with a value of 0-2346 bytes (I guess it's MTU + the MAC/PHY header ?) Where does this 7981 bytes come from, and can we have a definite answer on the 802.11 MTU size ? Is it 2304 bytes ? If MTU = 2304 bytes, what is the total frame size of a WPA2 packet (assuming the MTU is fully saturated) ? mtu. share | improve this question | follow | asked Jul 9. REMARQUE: Une fois que vous obtenez une réponse, prenez 1452 et ajoutez 28 à elle pour que vous obteniez la taille correcte MTU. Dans l'exemple donné ci-dessus, 1452 est la valeur correcte, et la bonne taille MTU doit être de 1480 pour le réseau que vous travaillez avec.

Ethernet's MTU of 1500 bytes limits the size of packets that traverse it. Sending a packet that is larger than the maximum transmission window for Ethernet is called jabbering. If unaddressed, jabbering can disrupt a network. Usually, jabber is detected by repeater hubs or network switches. The simplest way to prevent jabber is to set the maximum size of a TCP packet to no more than 1500 bytes MAC/Layer-2/L2 MTU; Full frame MTU; Full frame MTU. Full frame MTU represents the actual size of the frame that is sent by a particular interface. The value cannot be monitored and it is not configurable through RouterOS.

It basically sets up how much data you can transfer at a time at the lowest level. So, having a higher MTU means you can transfer more data at once and thus, have higher speeds. However, the MTU size is heavily dependent on the network equipment that is directly connected and the standard is usually 1500. Lower or higher than that, chances are you'll have.

If an IP interface's MTU value is different than a datalink's MTU value, IP packets are limited to the MTU value of the IP interface. For example, if a datalink has an MTU value of 9000 bytes and an IP interface as an MTU value of 1500 bytes, IP packets are limited to 1500 bytes. However, other Layer 3 protocols that are using the underlying Layer 2 protocol can send packets up to 9000 bytes Mac WiFi Problems are one of the common issues for Mac users.

MTU is short for maximum transmission unit. An MTU value determines the maximum number of bytes each time a sender can send. If the size of packets exceeds the MTU supported by a transit node or a receiver, the transit node or receiver fragments the packets or even discards them, aggravating the network transmission load.
