I had always the 200er version with data throughputs of 10-40 Mbps. My experiment with the 500 variant to achieve better results failed. It was even worse: max 20 Mbit - many crashes.
Now I have tested the 650+ version and was pleasantly surprised: Right away 70 MBit, which has then stabilized at around 85.
-> Who like me has a failure-prone environment, it should even let it a try.
