Congestion and slowness during Community Peak, Cox blames modem, tries to rent new one.
Before everyone had Stay-At-Home orders for Lakewood Ohio, I was working remotely and paying for 150 down bandwidth. That was my typical experience too, that bandwidth matched what I paid for it.
Increasingly over the past days and weeks, my bandwidth has been decreasing. Multiple conversations with Cox technicians have resulted in a recommended change of modem. This doesn't make sense, because the congestion is happening during peak hours and not at off peak. For example at 11PM and 4AM I don't have challenges. I'm somewhat knowledgeable about networking and have QOS priorities set in my house. I observe and limit devices that connect to my home network. I've been very careful and attentive to narrow down this problem.
This is a network congestion problem starting outside of my house and largely dependent on time of day. Yet, I'm asked to upgrade my modem because it is 'unhealthy'. My modem is on the approved list for DOCSIS 3.0 and appropriate for my service bandwidth. The modem works fine in off peak hours, and my demands on it are not changing (in fact my demands might increase because I use more bandwidth and devices at night for work).
I repeatedly asked if there are bandwidth guarantees I could pay for and the technician ignored those questions. I don't know why, since my other questions were answered.
I decreased my service to starter plan 10 down 1 up because that's what I'm averaging during the day, the technician said there was no price difference between the 10 down and 30 down plans, both are 49.99 in my area. So I'm considering cancelling and just tethering off my phone since it provides better bandwidth.
