hello
i use RB951-2n with latest routeros (6.11) as a dialup pppoe client for dsl connection and i have some connection issues and dropouts with periodic pattern (every n=12-15 seconds at which connection e.g.downloads pauses and pings times out). this lasts for 2-3 seconds then everything ok again. i use default configuration for pppoe-out with default mtu (1480) etc. i believe it has to do with mtu but i tried different values (1500-1460-1492) with no improvement. the port mtu (ether1) is default set to 1600 and i did try and set it to 1598 but no luck. any ideas???
As far as the MTU, I would verify with the ISP what it should be set to. Have you tried replacing the MikroTik with some other devices to test the Internet connection ans verify that it is being delivered without any problems?
actually ur right…the problem is the shitty OEM modem equipment from ISP changed SOLVED thanxs…
