those sort of errors should result in loss of a connection, not it slowing down. Anyways, the only thing I would say about your power levels is that your downstream power is a tad high but if you are achieving full speed on it then it is probs ok. I get my full speed most of the time although it drops to 35mbit in the evenings and normally 20 ish over the weekend. It doesnt mean anything is wrong, it is just that the network is busy. You may be in an even more over subscribed area than me which is why you are noticing more of a significant decrease in speed. If you had any probs with your connection, especially your power levels, it would affect you all the time and not just during peak periods
