Hello,
RUTX09 is capable to achieve LTE speeds of up to 300 Mbps.
However, according to your speed test results, it seems that your mobile ISP might not be able to supply 300 Mbps speeds in that particular location, since your devices caps slightly above 200 Mbps. If you will be receiving similar speeds with your RUTX09 in that particular location, you might want to try testing your devices in different location, where mobile ISP provides faster internet.
