Hello everyone.
I present myself, I'm Jordi, and I've logged in to your forum so I have a problem. I am usually using products of your brand to make my networks.
They work almost always very well.
When networks require linking, however, they almost always use Ubiquiti material.
This is where I found a dysfunction, which I did not know if it was Mikrotik or Ubiquiti.
I found out that a client and network user had problems with Skype communications. Every minute had a small loss of communication.
I was watching it could be, as the installation was new and the internet provider too. Until then, this user had an ADSL connection with very little capacity (2Mbps) but had never had this problem.
Now, I have contracted an optical fiber and have a 100Mbps symmetrical connection.
In the attached diagram you can see the entire network, where we found the problem.
As you can see there are two final customers that use the same fiber. Customers' routers (HAP AC lite) receive the internet signal for a VLAN generated by another RB750 r3 router, and collect a public IP for dhcp delivered by the provider.
The problem is that exactly every 60 seconds, 2 ping between the HAP and the RB750 are lost.
After many tests I have verified that this does not happen if the ubiquiti antenna that makes BSU has a certain firmware. And so I've let them know the brand's technicians.
One of the other tests I have done is to replace a HAP router for a PC and in this case whoever is the ubiquitous antenna firmware, there is no loss of ping.
I understand that the problem is an incompatibility between the two brands, which is why I also show the problem to you. As I have done with the other company.
I think that is not the only time someone has commented on this kind of problem, just look at google "loss 3% ping mikrotik" to see that on other occasions someone has encountered similar problems.
Could it be a routers configuration problem?
