Mikrotik router's ability to aggregate speed is real? , does not mean fail-over or load balance. It means two or more different Internet inputs from one ISP or several ISPs, for example, two 50 Mbps internets can be aggregated together and 100 Mbps internet speed can be provided to people through wireless or LAN?? We have done many tests and it failed with every configuration and unfortunately it is like this that it divides the speed of incoming internets by the number of them! And there is no increase in speed and it decreases and there is no solution!! what is your opinion??

with the default settings or any settings we made so that we even connected only one Internet input to the router !! and did not need to increase the speed or fill-over or load balance!!!!! it reduces the internet speed by 50% and offers both wireless and cable!

Routers do not aggregate speed. They can provide increased throughput available to all users and provide redundancy in case one ISP is not available.
Any single session cannot be more than the highest 'speed' of any one ISP connection. You are thinking of bonding etc......
Suggest your sources that told you it could, are NOT real.

Internet isn't like water pressure or electricity current.

The best you can do is load-balance between the uplinks.

Which is good as otherwise new MIkrotik users by now would have been already all dead (either drowned or electrocuted).
