My contract is nearly up with zen and I thought I would start looking around for other company's to see what deals are available. I went to the zen homepage and input my phone number to see what sync speed I would roughly expect nowadays and it was a big difference in what I am actually syncing at. Currently I'm syncing at 47.9 Mbps when the checker says I should be more in the region of 63.3Mbps. Now I understand that this is a ballpark figure and that over time crosstalk would play a part but not quite to that extent.
My ping time has also nearly doubled in the 2 years which to me is far more important. I checked my ping graph and noticed I have been getting weird lag spikes for around the last 6 weeks http://www.thinkbroadband.com/ping/share/d2478e3d792...
Would this also be cause by cross talk?
I have router stats available and can see lots of errors but apart from that I really dont know what they mean.
Looking for some advice about what the possible issues are.
