PharmDawgg Posted March 18 Share Posted March 18 Do you recommend entering a value here or just leaving it blank? I know the best MTU for my setup is 1500. Just wanted to verify. Thanks. Link to comment Share on other sites More sharing options...

DARKNESS Posted March 18 Share Posted March 18 @PharmDawggThat really all depends on your own network some are not optimized for 1500 so you just have to test it. It not too complicated just check the mtu using command prompt and find the one that doesn't give you packet loss and add 28 to it after you find the optimal one and that about settles it. You can leave it blank as your ISP will give you the highest one that there capable of automatically though as stated doesn't mean it optimized.

I'll give an example - I found my MTU manually. I started from 1500, everything required packet fragmentation until I reached 1472. That was ideal. Now if I add those 28 to that 1472, what do I get? Again 1500 and packet fragmentation!? Thnx Link to comment Share on other sites More sharing options...

The modem from my ISP is now in bridge mode. Someone told me that Netduma R3 gives less lag if the modem/router from my ISP are set to bridge mode, so the router works better, is that true?

DARKNESS Posted April 30 Share Posted April 30 @ZliYes that would be it...the reason why you get fragmentation when you ping your max mtu is because it exceeds the limit of what it able to fragment. As for the bridge it depends how the device handles it but typically bridge is better as it just using the modem mode only. Link to comment Share on other sites More sharing options...
Fuzy Posted April 30 Share Posted April 30 The standard: MTU TCP/IP Ethernet: 1500 bytes PPPoE: 1492 bytes ADSL: 1468 bytes For information, online games use the UDP protocol.

Well it ensures all devices are being controlled by the R3 so yes it would work better in that scenario Link to comment Share on other sites More sharing options...
