Hello how are you? I have a problem with changing the MTU of the Router, by default the MTU of my PPPoE Client comes in “1480” and the LAN and WAN in “1500” What I want to do is put my MTU in “1492” But I can’t change it in The PPPoE Client, When I try not let me modify it, how is it possible? Thank you
You can not set max MTU?
If you create a new PPPoE client, before saving, can you type in the max MTU field?
When I tilt my head far far enough I see as interface Modem and may have other rules as a ether interface.
Exactly I do that but in windows it still shows me an MTU of 1480 and not 1492
Max MTU and MRU apply in 1492: http://prntscr.com/prp17k
I lose packages the same way. http://prntscr.com/prp0tu
I don’t understand…!
As i can see your MTU is changed to 1492… so?
Yes in the Mikrotik yes but on my PC I still get 1480
I already tried all the truth and I don’t know what else to try, I know that my ISP handles 1492, if I use another router I have 1492 but with Mikrotik I have 1480 … I don’t know what else to do and about this there is very little information on google .
What do you mean you have 1480? How do you test that?
Where is the PPPoE server? Your ISP?
If you ping CMD, it tells you the MTU that the router has, in this case I have 1480 and I need 1492, and the default PPPoE of my ISP is 1492
Since your MikroTik shows 1492 Byte of MTU, then the only reason you cant pass more than 1480 should be your ISP…
But that is impossible as I said, if it were my ISP I should not have 1492 in the modem that they place and with my previous TP-LINK router I had 1492 my ISP is not the problem.
I have seen that actual MTU is coming for some of my customers are getting 1480 and 1452.
I’m confused
You can set the PPPoE MTU, but you don’t type it in where it says “Actual MTU” you type 1492 into “Max MTU” and “Max MRU”
The way MikroTik works with its PPPoE clients, if it can’t successfully carry the requested size (or you don’t enter one) it will drop back to 1480.
Even if the line can carry 1492, it will still drop back to 1480 unless you manually type it in
I could already change the MTU, the problem was that when I reset the router it loaded the initial configuration and did not leave it at 0, I did a reset and the first time I opened it I put in removing configuration and then I changed the MTU, Thank you all for answer.
Honestly i understood nothing…
When I restarted the factory router, I loaded the initial configuration and did not press where it said “Delete initial configuration”. Then I created rules and other things in the Firmware automatically and that didn’t allow me to change the MTU, I’m sorry to use a translator.
I had to press there at the beginning.
If it worked after a reset with remove configuration then it is obvious there was something wrong with your previous configuration…
