I've wondered about upgrading to a faster plan when speeds are less than expected. It sounds like you upgraded and still aren't getting speeds indicated for the plan you have. But, did upgrading your plan improve your speed from what it was before the upgrade or did it remain basically the same? I'm wondering how Cox allocates available bandwidth.
A. Does Cox pro-rate available bandwidth based upon a percentage of each person's plan? Or, B. Does Cox try to give everyone the full speed intended for their respective plan?
If it's option A, then upgrading to a faster plan should result in some incremental increase in speed, albeit not to what the plan indicates. If it's option B, an upgrade to a new plan wouldn't improve performance since Cox was already unable to provide the lower plan's expected speed. An upgraded plan would just produce the same result as before at a higher cost.
