The donation came as the company was pleased with previous cooperation with the university's donation fund - in late 2015 Mikrotikls donated €424,000, used by the university to support 12 projects in IT, medicine and natural sciences.
"The donation gives a sense of great responsibility and provides an impetus and energy to seek broader horizons, so that we can one day be proud with Nobel Prize-worthy scientists and their discoveries," said Laila Kundziņa-Zvejniece, the executive of the fund.
Altogether Mikrotikls has donated €1.5m to the University of Latvia, making it one of the largest donors ever.
Mikrotikls is a Latvian IT company known for its wireless routers. Most of its production is exported.
Previously Mikrotikls donated €1m to a children's hospital.
