Hello, I'd like to receive some thoughts about a mikrotik p2p link for high distance. What I need is a REAL 100mbit throughput with the help of the mikrotik routerboards. The distance is about 22-25 km. Is that possible? If someone has a setup that matches what I need , please share.

you can check in wifi part of the forum on what should/can be done to make such a link. Use wifi calculator to plot the link, check the area for interference.
