![]() Change your MTU under Vista, Windows 7 or Windows 8 richard- slater. October 2. 3, 2. 00. I have been updating this blog post over the years since I first discovered the issue with my computer in Windows Vista, now I am on Windows 8 and also on FTTC broadband; Path MTU Discovery seems to just work. I have tested the process so the approach and the commands still work in Windows 8, I however no longer need to use this process personally. For some reason that has escaped me Path MTU Discovery (PMTUD) in Windows just doesn’t seem to figure out the MTU for a given path (something to do with routers being poorly configured to not respond to ICMP requests). So Windows uses the default. For the most part this doesn’t affect anyone, however if it does affect you, it really annoys you. Failure of PMTUD will result in some websites not loading correctly, having trouble connecting to normally reliable online services and general Internet weirdness. The resolution is to set your default MTU to one lower than the Ethernet default of 1. Here is how: Step 1: Find your MTUFrom an elevated Command Prompt in Vista/Windows 7 or the same elevated Command Prompt in Windows 8 enter the following command: netsh interface ipv. You should get something like this. MTU Media. Sense. State Bytes In Bytes Out Interface. Loopback Pseudo- Interface 1. Local Area Connection. If you are using Ethernet cable you will be looking for “Local Area Connection” or “Ethernet”. If you are using Wireless you will be looking for “Wireless Network Connection”. The MTU is in the first column. Step 2: Find out what it should be. In the Command Prompt type: ping www. The host name should be a site you can not reach, - f marks the packet as one that should not be fragmented the - l 1. Ethernet Default MTU – Packet Header, where the Ethernet Default MTU is 1. Packet Header is 2. If the packet can’t be sent because it would need to be fragmented you will get something similar to this: Packet needs to be fragmented but DF set. Keep trying lower packet sizes by 1. Raise your packet sizes by one until you get a “Packet needs to be fragmented but DF set.”. The last successful value plus 2. MTU value. In my case a packet size of 1. Step 3: Set your MTUNow you have identified the interface you need to change and the ideal MTU for you, now it is time to make the change. Again from an elevated Command Prompt type the following replacing my MTU of 1. ![]() ![]() ![]() 165 Responses to “Change your MTU under Vista, Windows 7 or Windows 8” hi man my problem is : my win is 8.1 I follow your steps and raised my packet size till.
