Airtel Uganda 5G Internet box very slow

Airtel Uganda provides the 5G internet box but in one of the cities of Uganda, Mbarara city, there is no coverage for 5G. This is in the middle of the Business Center. The internet is extremely unstable and unreliable that you have to always reboot everytime it is not working. On an event of after a successful reboot, internet can do a max of 16 - 17Mbps and in a few, it will be back to default, 3 - 5Mbps. This internet is extremely unreliable and 5G is a scam in Mbarara city.
