Mikrotik

When you see an fcs error it is almost always the cabling on the radio at the other end of the link from where you see the FCS errors.

You can change cables over and over again on the side where the FCS occur and have minimal results.

It can be a bad cable from media converter to Mikrotik, bad media converter, the problem with fiber optic cable between 2 media converters, port on neighbor device and of course port on Mikrotik.

Mikrotik Fetch Tool is one of the tools on the console/terminal Mikrotik RouterOS that works to copy (copy) files through FTP, HTTP, and https protocol. This Fetch tool can copy files from other devices to Mikrotik Router (download) or copy files from Mikrotik Router to other devices (upload). So its use is similar like wget on linux, with the different command.

Until RouterOS version 6.38.1, Mikrotik fetch tool still no fetch menu in its Winbox GUI. So to use this fetch tool we still have to type the command on Mikrotik terminal. It does not matter because the use of his command will be discussed one by one in this Mikrotik Tutorial until easy to understand.

If you are in the informatics sector, it is impossible for you to come to a point where the Mikrotik router does not come.

There are two important points here.

1 – Bridge behind a Mikrotik modem (Username password is defined in Mikrotik)

2 – It is accessible from the outside as a DMZ / NAT behind a Mikrotik modem.

In both methods, a WAN IP belonging to the Mikrotik device (this is the local IP in option 2.) I also assume that there is a LAN IP (Local, camera, office IP, etc).

If users in the company use facebook, youtube, Instagram, log out from a different modem.
The internet used for the business to log out from another modem.

To perform this operation, you need to create a scenario in a few steps.

1- We need to determine our target ip addresses. On this side, version 6.3x started to accept the Mikrotik domain input together with it. We can specify a domain name in the address list, and these domains automatically resolve the strings.

One of the most widely used areas of mikrotik is the use of hotspots. In some cases, hotspot users may need to be shut down automatically or automatically.
For these cases, let’s make a statement with the examples below.
First of all, it is necessary to make sure that the date and time of our mikrotik device are up to date and constantly updated. This plays an important role in the timing of the rule.
