Hex RB750Gr3 Switch issue

Fri May 18, 2018 3:16 pm

Hi Guys,

New here and new to the world of Mikrotik and RouterOS. Been wanting to take a dive for a few years and finally done it. Bought my first Hex and a Hap Lite to have a play around with and replace my RT-N66U loaded with tomato.

Basically I have been having problems with my new IPTV Box (Youview) that uses multicast to stream, it has been drowning my current router and causing problems due to high cpu load and dropping wireless connections or restarting altogether.

I have been trying to set up multicast on the Hex but found it not as straight forward with the obviously steeper learning curve on rOS, I did find a great idea on this forum which involved forwarding all the traffic at switch level from the port that the IPTV is on directly to the port the ISP is on. See link here - viewtopic.php?t=86582
After trying this it appears my router's switch is not cabable of this as described here https://wiki.mikrotik.com/wiki/Manual:S ... p_Features under the MT7621A.

Is there another clever way of doing this? My modem is a Draytek Vigor 130 running in bridged mode and the router connects using PPPOE so a PPP interface.

Also I am wondering if anyone has any valuable sources i.e books or udemy type services where I can learn in my own time about advanced networking and MikroTik. I have tried udemy but not found it very resourceful.

Many Thanks
Mike

Thanks CZFan,

I had already tried those pointers a couple of times but couldn't get it to work. But I didn't give up, I decided to properly mess around, after many reset to default config's...

I managed to get it working after playing around, I used the same method as you linked however my traffic was not coming from ether5 (even though my STB is connected to ether5) the traffic was coming from "bridge" as the default configuration has all LAN ports bridged. I tried this without bridge but got lost. Once I changed ether5 to bridge traffic started flowing.

The other thing I was missing was I didn't realise you could move firewall rules around to prioritise them, my connections kept getting blocked as the allow rules were below in the order list.

After much messing around I have the IPTV working, I will be monitoring how this affects the RouterBoard because this similar setup was destroying my old trusty Asus and don't want to end up in the same situation. If anyone has any better solutions, would be greatly appreciated.

Another option I set was "IGMP Snooping" on the bridge.

I hope that having the LAN ports bridged doesn't mean that the other ports are going to be flooded, but I don't know, is there any way to monitor?

Thanks
Mik

Good morning chaps and chapattes.

Just to update on the issue I was having above with IPTV, the issues are fully resolved and everything is working great. The guides posted above just need a bit of tweaking as per your own situation.

There has been another problem however I don't think these are linked ( but they could be ).

My second router (WAP Lite) which is configured using capsman, after a few weeks of flawless operation seems to be losing it's security configuration. I cannot seem to pinpoint yet when or why this is happening exactly. The devices when connecting get greeted with an incorrect password error.

As a temporary measure until I get time to properly investigate it, I have set up a daily reboot at 3am as a reboot seems to fix it.

Thanks
Mike

Are these devices greeted with incorrect password by any chance Apple devices? If so, what happens when you go closer to the wAP device?

They are indeed, heavily Apple dominated household here. Moving closer makes no difference, I was testing whilst next to it with my iPhone and MacBook Pro.

it's the hAP Lite as well sorry, RBRB941-2ND, not a wAP.

Is there a common issue on Apple devices currently?

Thanks
Mike

There are always issues with Apple, Apple is common ;-)

I experienced same symptoms with my Apple devices, i had to actually go to literally centimeters away from my Wifi router with my iPhone, only then it would connect again and accept user and password

Moved to Android phones, no more problems

That is the most ridiculous piece of advice I have heard today (I just woke up).
If mikrotik wifi doesnt work with apple phones, I am returning all this junk!!!
Android phones are a haven for malware and crap.................... ewwwww I feel infected just thinking of android phones.

Lots of issues with Apple wireless especially with older generation gear ..... newer generation Apple wireless [AC] work much better after they switched to Qualcomm based chips. .... FYI Ubiquiti forums full of people complaining about older gen apple wireless gear --- nightmarish proportions

Agree that Android is malware paradise ...... but wireless works great :D

You can take it or leave it, no skin of my nose

Wakeup call, it is not just with Mikrotik this problem, same issue with many other products

Interestingly, another similar thread with no resolution here viewtopic.php?p=627225

My iPhone is an iPhone SE, two years old now, however discover the same issue on my MBP which is 2017 model. My AP isn't using AC however, my AP is set to b/g/n 20mhz.

CZ, What AP do you use that you had issues with? Also do you have multicast traffic on your network?

Thanks
Mike
