High latency + packet loss (Luton)
 

Hi there,

I've recently started experiencing problems with my connection which is making it impossible to play games or stream media during peak hours. I have already posted on the newsgroups but I wanted to see if any of you guys could offer some advice, I've attached my modem info and some tests below.

The lag has only hit recently, so I do not think my hardware is to blame. If I run a pingtest in the morning (7:30am) the connection is perfect and is rated an A with 0% packet loss.
