Maybe, I'm reluctant to blame crosstalk because the drop occured overnight, during which there was downtime for several hours due to "network maintenance and upgrades" in my area. Since then the speed has returned and then gone back down again.
It's too much of a coincidence for my likeing, if it was crosstalk I would of thought the speed drop would be gradual and interleaving be applied first followed by a speed drop if necessary. Or is that not how it works?
Edit, also wouldn't the attainable UL speed drop aswell if it was crosstalk or are only the DL frequencys effected by crosstalk?
