The same has happened to me since I've started playing. My internet was just peachy until then too, and I've tried all the steps to no avail. Apparently the problem is that this will happen during peak hours. If I play outside these hours (Usually 11:00 AM to about 6:00 PM, PST) I am fine, but that's still the greater chunk of my waking day. Hopefully this is fixed before they start charging us monthly.
