M200 Slow Upload speed

For last several days I'm experiencing slow upload speed. It is in range 1.2Mbps-2.5Mbps . With 200Mbps connection I'm expecting about 20Mbps.
I'm runing speed tests both on Wi-Fi and Ethernet connection and result is the same. And obviously exuipment been reseted between tests and it make no difference.
Heres required data from Hub 3.0

Re: M200 Slow Upload speed

Your upstream channels are out of spec, which explains the slow upload speed:

Upstream bonded channels

Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID

1537000003.846512016 qam10
2393998613.725512016 qam12
3462001613.775512016 qam11
4603000003.7512016 qam9

 

The highlighted values should be 64 QAM.
