Upload speeds halved (M350)

Hi,

I am consistently struggling to get over 15Mbits/sec upload, where previously was consistently getting 35-38Mbits/sec.

Upstream power levels look a little high, at least..

Stats following reboot:

Re: Upload speeds halved (M350)

This is still an issue.  Upload speed down to 3.9Mbps this evening, and upstream channels down to 16 / 32 qam and power levels on the high side:
