Mtu packet size windows

Though when following the steps, and the similar steps you see in web articles, i receive the following response. So i have did a little bit of digging around, and found how you can change the MTU Settings by using your mouse instead of headache responses via command prompt or powershell.

Type the following with out "" "View Network Connections" Then click to open. Next a window will open showing all of your network adapters, Both wireless and lan if you have more than 1 network adapter. In this case my Ethernet adapter i will be using is labeled "Ethernet 2", Your network adapter name may be different. After clicking the Configure button circled in red, another small window will open up.

Humans of IT. Green Tech. MVP Award Program. Video Hub Azure. Microsoft Business. MTU Size Matters. Joel Vickery. Published Nov 21 PM The Problem "The internet is down! My teenage son, who plays virtually every game known to mankind, could not join the majority of game servers for his favorite game.

There were a handful that connected with no problems but naturally those were not the ones that his friends were on. As you can imagine, a travesty of justice of this magnitude does not sit well with a teenager who is being deprived of the "highly educational" banter of his friends as they defend the world from zombies or mindlessly run goats around a city.

Don't get me wrong, I am thankful for their service and realize that we would be up to our eyeballs in zombie goats without them. Troubleshooting After checking all the usual suspects in troubleshooting permissions issues, UAC, local and network firewall, proxy I was drawing a blank. I was not surprised by that since most issues at those levels are binary, either blocking or not with no in-between.

I finally decided to run a network capture to see if I could get any information that I was not seeing in any of the the computer's logs. We ran a network capture of the session connection in both a good connection to an online server, and a failed connection attempt. Gratuitous Free Product Plug To view the network capture, I loaded the them into Microsoft Message Analyzer, which to this day, I am amazed at how few people know about and use this program. It is the next generation of analysis tool, replacing NetMon and is much more than a network protocol analyzer.

I highly recommend checking it out and getting to know it's capabilities. It's free, it's awesome, download it! By comparing the two captures side-by-side, I was able to find an ICMP packet that looked out of place and was only present in the bad capture that was the key to solving this problem. Take some time and learn the filtering syntax.

In this case, the filter that we want to show packets that would indicate a fragmentation issue would be: icmp.

Also note that the packet length was only , which seemed excessively small. MTU or Maximum Transmission Unit is a setting that basically tells your computer how much data to put in a packet to send over the network. This method affects packets sent to all destinations. Most of the time, the performance will be at acceptable levels with a packet size of In the Value data box, type 0, and then click OK.

If you set the MTU size for a network interface manually, this setting overrides the default MTU for the network interface.

The MTU size is the maximum packet size in bytes that the transport will transmit over the underlying network. This method affects packets sent to all destinations and may significantly affect the performance, depending on the MTU size that you set.

To set the MTU size for the network interface, follow these steps:. For more information, click the following article number to view the article in the Microsoft Knowledge Base:. Need more help? Expand your skills. Get new features first. Was this information helpful? Yes No.
