Hello

I hope i'm writing in the right section.

I'm having trouble using netlix. if i want to use the website oftentimes it won't load. Just say that the it timeouted, when i refresh couple of times then it will load.
Problems also with using app. if i'm watching series oftentimes it takes some time to start playing then when it finishes it doesn' go clean to next but only the timer runs out and after some time it starts playing on...

i tried with Wifi and same problem. i know that something must be with the router.. i tested my computer by using hotspot from my phone and worked normaly.
i also saw, that there ware some topic about it.

My router:
RB4011iGS+5HacQ2HnD-IN
Current FW: 6.47.4
Factory FW: 6.45.8

Can anyone please tell me what could be the cause of that?

Hi,

I'm using Netflix with a Miktrotik router without any issues.

When all other websites work on your device properly, it is apparently a Netflix-only issue. Try to use a different browser (e.g. Firefox) in this case.

I hope that helps, Hannes

No known issues with using Netflix that I am aware of????

MSS problem, try to use "clamp-to-pmtu" to fix it, or manually lower your MTU

Default router config should work fine.
Try remove Router and connect PC directly to ISP and then see if it works fine to rule out Router problems.

I can also confirm that this is happening

Normaly my MTU on PPPoE interface is 1480 and then Netflix doesn't load

if I manually change MTU(on PPPoE client) to 1500 (like I have on ethernet interfaces (ether2 for example) then netflix works but who.is: https://who.is/
doesn't


when I change it back to auto, netflix doesn't work but who.is does

I also have clamp-to-pmtu rule applied but it doesn't help at all

We tried to set MTU max and MRU max to 1500 and for few hours it seemed to work but not for long i also noticed that if it was set to max 1500 i couldn't open mikrotik forum or cablemod website.

We know that there is some setting wrong/missing or something in the router.. done some troubleshooting.

As always, first things first: Update software to latest long term release and also update firmware to same release in system/routerboard

Try to decrease MTU, not increase. My MTU is 1480, I have IPv6 enabled, Netflix failed to load, what I did is set MTU in IPv6 to 1440 and Netflix works again. I end up settle in keep original 1480 MTU and use clamp-to-pmtu, now everything works

I also have IPv6 enabled.
Tried lowering to 1400, no result, same for 1300.
1200 little resault.
at 1100 netflix started to work normaly and other websites. i'll leave it at that and monitor the situation.

My MTU is 1480 and I don't have any issues.

I also have IPv6 enabled.

What exactly are you using?

search the forum a little, doesn't hurt:

Sometimes it depends on your ISP

I see that i'll need to reserch a bit more. Found out, that while most websites work normal... one game doesn't .. if MTU and MRU are on 1100 Overwatch doesn't connect... i'll have to experiment a bit more...

If those websites/games are IPv6 aware, your LAN IPv6 MTU is dictated (as stated in the topic mentioned above) by IPv6/ND, which by default is 1500, messing with your WAN is useless at this point.
As (again) stated in the above topic or the one mentioned in there, you either set the proper MTU in IPv6/ND or clamp mss to pmtu. https://www.reddit.com/r/mikrotik/comme ... o_clients/

Tried setting MTU in IPv6 to 1480 seems to work. did not find webs site or game that has problems now :)

What brings you here with such a request after two years, @Jotne?
