I have a 1gbps network speed from an ISP. After configuring the CRS112-8G-4S-IN router, I will only measure about 30mbps at https://www.speedtest.net/. At intervals of about 3 minutes, the connection drops and starts up again in a moment. Where could be the problem?

I made the configuration based on this video: https://www.youtube.com/watch?v=rvsAlWxANoQ

According to this video, it worked on my other CCR routers without any problems.

The CRS112-8G-4S-IN won't be able to handel the Routing of ISP-Speeds of 1Gpbs
If you take a look at the Mikrotik-Webpage (https://mikrotik.com/product/CRS112-8G- ... estresults)
I wouldn't expect more then 32.8Mbps with this device / configuration

So you got 1gbps network speed from an ISP.
And you watching youtube videos how to set it up?
I'm assuming that you are you are not going to deliver internet to the customers
