Hi, all,

I have an issue with my Mikrotik.
When watching video online, the streaming will lag.

What's the setting I need to set ?

Thanks.

What Mikrotik? What video? What provider? WiFi or LAN? What speedtest result? What's your config?

I had a similar prob once. It was due to too many Mangle rules in Firewall. Maybe that's your prob too.

Mikrotik - hAP ac RB962UiGS-5HacT2HnT

Video - Facebook, MI Box

Povider - Unifi 30 Advanced, when watching MI Box LAN, when watching video at Facebook, wifi

Speed test - download 30++mbps, upload 9++ mbps

What's your config - Just normal setup for Unifi, I had changed the port at Miktortik for MiBox to 100mbps, uncheck the 1000mbps still same.


One more issue i facing is, I can connect to office VPN but Microsoft Outlook not able to connect to exchange server. But I able to connect to the exchange server when use the hotspot from my phone.

chongky Speedtest is good means not the router's problem already. Something wrong with TM (routes, congestion, sharks, etc...). I'm facing slow iTunes downloads. Let me try FB and see if I have the same prob. Sorry, no idea about Outlook/Exchange.

FB for me seems OK (videos and all)
iTunes going at 1-2mbps (small b)
Steam OK
Torrent OK
Battle.net OK

Guys, the usb port can support 2 usb modem? Or have to use powered usb hub?

guys,I have been trying to configure(using soonwai's and klseet's guide) my Mikrotik for ipv6 using Unifi but it keeps saying that the status is searching.Some help would really be appreciated

wanttotree, I'm doing the same thing. I only pulled 1 cable during renovation and was using HomePlugs for HyppTV. That was before I discovered Mikrotik routers. Got rid of the homeplugs and trunked vlan 1 & 600 from my RB upstairs (my modem is upstairs) to my RB downstairs. I was just wondering how you are doing the vlan trunking. Are you using vlans and bridges? I'm using this method. Or are you doing it in the switch config on the RB.

To be honest, I'm not sure if I'm doing the right way but it works so far.

Are you requesting both address and prefix? If so just prefix will do. If that doesn't help, post your config so we can have a look. Also confirm that ipv6 is already available in your area?

Hard to say but probably not for 2 modems. It really depends on how much power they need and how much the RB supplies. I don't think Mikrotik publishes this data but if they follow USB 2.0 specs then it should 500mA. At 5V, thats 2.5w.

Thanks soonwai,

I've put my web fig settings below but am really scratching my head on where I went wrong here.I played around with the prefix bit but still nothing successful

OK, let me try. Based on your screenshots:
1. For DHCPv6 Client, request only Prefix. (Try this and check ipv6 address and see if you get anything)


2. What's this screenshot? I'm using 6.38.1 so things might look different.

3. Disable the DHCPv6 server, Mikrotik's DHCPv6 Server only hands out prefixes and not addresses so it's of no use to the PCs in your lan. Your devices will get their IPv6 address via RA.

4. For ND, Neighbour Discovery, no need for "Interfaces: All", just your bridge-local is enough. And enable Advertise DNS.

Do #1 first and see that you are assigned a Prefix from TM before going further.

yeap im doing vlan and bridge. i also am not sure that its the absolute right way to do it. but so far it works flawlessly. so i am not complaining. if there is better way i can try, please suggest here, i would be grateful for any recommendation.

Couldn't find any info how much do the devices draw the voltage either. Am asking because my multi plugs on the wall sockets are so full, and voltage regulator is on the multi plug, and few more multi plugs on the regulator. All fully occupied currently. I seriously worry about short circuit.

sikentut your modem support ipv6? Like mine, old adsl modem doesn't support, so no ipv6 for me.

I am on Unifi and have been using IPv6 since using Asus RT-N56U. Havent been able to figure out IPv6 on Mikrotik

It shouldn't be this difficult. One more thing to check. Your UniFi PPPoE Client's Profile should have "Use IPv6: Yes". Or maybe post a "/export compact" then we can have a look. Don't forget to remove any credentials from the export.

I know what you mean. Same thing here. My daughter says I'm playing Minecraft with all the power blocks.

Thinking about this, the modem shouldn't matter right? I mean it's just a bridge.

1.Am back to square one

Requesting merely prefix doesnt make it work



2.Am using 6.39rc25.Screen looks a bit different as its webfig

3.Have removed the the server but its still searching



4.Have changed the interface but still cant get a request in

Your UniFi PPPoE Client's Profile have "Use IPv6: Yes"?

Turn on logging for DHCP and see if there're any useful messages.

Always possible that it's a prob with 6.39 RC, maybe you found a bug.

My client profile has IPv6 enabled



I have placed my settings at https://zerobin.net/?4010e0fb244dac68#vYnqT...uzmfdhvTLis4is=

Just had a quick look and looks OK to me.

In /ipv6 address. do you get a local-link address for your pppoe client interface (Unifi in your case)?

Like this:


I didn't check the firewall rules. You have a lot of them. Could be something in there. Try disabling all filters for ipv4 and ipv6 and see what happens.

If that doesn't help, I'm out of ideas.

sikentut Ignore my previous post and try this. Add this rule in /ipv6 firewall filter. Make sure it's before the Drop Input rule that you already have.

Thank you Soonwai.It works perfectly!

No problem. Glad it worked.

For those who might be interested, the above rule accepts traffic to port 546 which is the DHCP client port. Without that rule, traffic to the input chain is dropped by the catch-all input chain drop rule and the dhcpv6-client never sees any reply.
