Hello, i have EXACTLY the same problem. I only switched to infinity today and for the past month, evening download speed has been slow as 3 mb/s (i have 16mb/s for the past 2 years every day). Funny thing is, upload is remaining fine.
Please HELP me as well!
What are your speeds like this evening?
I've been on Infinity for a couple of months now, and while I only check from time to time or if I notice something amiss, I've only had a couple of ocassions when it's been slow.
Just checked at 7pm, and I get my usual 37mb download?
