if i remember correctly this is a software bug but I thought they had fixed it. Although it is reporting qpsk in the upstream tab, when you look at the upstream burst tab you can see it is 16QAM. Normally qpsk is nothing to worry about and your modem will default to it when there is noise on the network because qpsk is more noise tollerant. Some people moan about a decrease in speed but the two times I noticed it when I was on 50mbit I was still able to get my max upload speed so it isnt anything to worry about.
